&lt;a href="https://en.wikipedia.org/wiki/Wanderlust"&gt;wanderlust&lt;/a&gt;, I searched for another
trail. This time, I wanted a shorter one as I was planning to do it as an
after-work excursion in the late evening. It should be close to home, easy, and
feasible in about an hour. The choice was quickly made. I decided to do a
trail in the small town of Lasauvage called &lt;em&gt;"Sentier de la Crosnière"&lt;/em&gt;.&lt;/p&gt;
&lt;h3 id="from-a-wild-woman-to-herons"&gt;From a wild woman to herons&lt;/h3&gt;&lt;p&gt;&lt;a href="https://en.wikipedia.org/wiki/Lasauvage"&gt;Lasauvage&lt;/a&gt;, known as &lt;em&gt;"Zowaasch"&lt;/em&gt; in
Luxembourgish, is a small town in the south-west of Luxembourg. It is one of
the few French-speaking towns in southern Luxembourg, many of which have a
long history with the local steel industry. The local ironworks in Lasauvage
were the first in the country to use &lt;a href="https://en.wikipedia.org/wiki/Minette_%28ore%29"&gt;minette
ore&lt;/a&gt;, for which Luxembourg is
renowned and on which much of its wealth was built.&lt;/p&gt;
&lt;p&gt;There is an oral tradition (German: &lt;em&gt;"Sage"&lt;/em&gt;) that explains the town's name. I
have copied it here verbatim, including the old spelling with the long s (ſ)
and &lt;em&gt;"eszett"&lt;/em&gt; (ß).&lt;/p&gt;

  &lt;h4&gt;120. Die wilde Frau zu La Sauvage&lt;/h4&gt;
  &lt;p&gt;
    Vor Errichtung des Hüttenwerkes zu La Sauvage, zu Ende des erſten Viertels
    des &lt;i&gt;XVII.&lt;/i&gt; Jahrhunderts, war dieſes romantiſche Thal unbewohnt und
    führte des Namen &lt;i&gt;Val de la sauvage femme&lt;/i&gt;. Dieſen Namen hatte es
    erhalten von einer wilden Frau, die ihre Wohnung in einer der Höhlungen des
    Felſens &lt;i&gt;La Cronnière&lt;/i&gt; hatte. Nach der Ueberliferung nähre ſich die
    wilde Frau von rohem Fleiſche; ein dichtes Haupthaar, das ſie umhüllte und
    bis zu den Füßen herabhing, diente ihr ſtatt aller Kleidung. Ihre rot
    umränderten Augen, dicht an der Wurzel des Haupthaares, ſchienen glühende
    Kohlen zu ſein; ihre Stimme tönte wie unheimliches Eulengeſchrei, und ihre
    Finger waren mit ſcharfen Krallen bewaffnet, womit ſie das im Laufe erjagte
    Wild oder die auf den Feldern erbeuteten Schafe zerriß.
  &lt;/p&gt;
  &lt;p&gt;
    Als die wilde Frau zum Sterben kam, ſoll ſie in der Hölle keine Aufnahme
    gefunden haben, da man ſie für das Weibchen eines wilden Tieres hielt. So
    war ſie wieder zur Erde heraufzuſteigen genötigt, zum Entſetzen der ganzen
    Umgegend, die ſie nächtlich als ſchreckliches Geſpenſt durchſtreifte, bis
    endlich ein frommer Einſiedler aus dem Walde Selomon den Geiſt der wilden
    Frau jenſeits des Meeres bannte. Er that es unter Anrufung des hl. Donatus
    und Unſerer Lieben Frau zu Luxemburg, deren heilige Bilder zum Andenken an
    die wunderbare Befreiung in dem Felſen &lt;i&gt;La Cronnière&lt;/i&gt; aufgeſtellt
    wurden.

&lt;p&gt;The passage above recounts the legend from which Lasauvage is said to have
taken its name. Before the ironworks were constructed in the early seventeenth
century, the valley was supposedly uninhabited except for a wild woman who
lived in a cave in the &lt;em&gt;"La Cronnière"&lt;/em&gt; rock formation. According to the story,
she ate raw meat, wore only her long hair and had glowing eyes, an owl-like
voice and sharp claws. After her death, when she was denied entrance to Hell,
her ghost reportedly haunted the area until a hermit banished it by invoking
&lt;em&gt;"Saint Donatus"&lt;/em&gt; and &lt;em&gt;"Our Lady of Luxembourg"&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The passage refers to the valley as the &lt;em&gt;"Val de la Sauvage Femme"&lt;/em&gt;, meaning
&lt;em&gt;"Valley of the Wild Woman"&lt;/em&gt;. This name was eventually shortened and
transformed into &lt;em&gt;"Lasauvage"&lt;/em&gt;. The Luxembourgish name &lt;em&gt;"Zowaasch"&lt;/em&gt; is actually
just a phonetic borrowing of the French name. If you say the French word
&lt;em&gt;"sauvage"&lt;/em&gt; and write it down as you hear it in Luxembourgish, you will
probably end up with something very close to &lt;em&gt;"Zowaasch"&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;A small stream flows through the town. Its official French name is the
&lt;a href="https://fr.wikipedia.org/wiki/Ru_de_la_C%C3%B4te_Rouge"&gt;&lt;em&gt;"Ruisseau de la Côte
Rouge"&lt;/em&gt;&lt;/a&gt;, but it is
also sometimes called the &lt;em&gt;"Crosnière"&lt;/em&gt;. It is this stream that gives the trail
its name. I find the coincidence with the name of the cave remarkable. In fact,
the two names are sometimes interchanged, as can be seen in &lt;a href="https://viewer.eluxemburgensia.lu/ark:70795/c3ncwbkv8k/pages/11/articles/DIVL191?search=La%2520cronni%25C3%25A8re"&gt;this news
article&lt;/a&gt;
from 1973. In Luxembourgish, this stream is called &lt;em&gt;"Réierbaach"&lt;/em&gt;. &lt;em&gt;"Baach"&lt;/em&gt; is
simply Luxembourgish for &lt;em&gt;"stream"&lt;/em&gt;, and &lt;em&gt;"Réier"&lt;/em&gt; is Luxembourgish for
&lt;em&gt;"Heron"&lt;/em&gt;.&lt;/p&gt;

&lt;h3 id="the-little-town-of-lasauvage"&gt;The little town of Lasauvage&lt;/h3&gt;&lt;p&gt;To reach the parking spot, I drove from my hometown along some country roads
and through a few winding turns down into the valley. Then, after crossing a
small tunnel bridge, I entered the small, peaceful and somewhat secluded town
of Lasauvage.&lt;/p&gt;
&lt;p&gt;The trail starts near the &lt;a href="https://differdange.lu/en/discover/auberge/"&gt;&lt;em&gt;"Auberge an der
Schoul"&lt;/em&gt;&lt;/a&gt;, a hostel where you can
book a stay, which is located in Lasauvage's primary school. The school still
houses the &lt;em&gt;"Lasauvage School"&lt;/em&gt;, the &lt;em&gt;"Nature School"&lt;/em&gt; and a &lt;em&gt;"puppet
theatre"&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;From there, I passed the first information panel on the trail, which you can
see below. It discusses how the stream was used as a source of energy for the
first blast furnace in Lasauvage by damming it at various points. However,
sometimes there was not enough water, and on those days, the workers were sent
home without pay. In the 1870s, the steelworks in Lasauvage were closed, as the
hydropower could not compete with the newly emerging types of energy, such as
electricity and steam. However, the mines continued to operate and the ore was
smelted in Rodange or Differdange.&lt;/p&gt;

      &lt;h5&gt;Die Corsnière - Wasserkraft für die frühere Eisenproduktion&lt;/h5&gt;
      &lt;p&gt; 
        Ab 1623 lieferte das Wasser der Crosnière die Kraft für den ersten
        Hochofen von Lasauvage: Pochwerk, Blasebälge und Feinschmiede wurden
        von großen Wasserrädern angetrieben. Dafür musste das Wasser an
        verschiedenen Stellen gestaut werden und so entstanden die ersten
        Weiher in Lasauvage. Verschiedene Kanäle wurden angelegt um das Wasser
        an zu liefern und dem Bach wieder zu zu führen.
      &lt;/p&gt;
      &lt;p&gt;
        War nicht genügend Wasser vorhanden, so mussten die Arbeiten in den
        Pochwerken eingestellt werden. Die Arbeiter wurden nach Hause geschickt
        und verdienten an diesen Tagen kein Geld.
      &lt;/p&gt;
      &lt;p&gt;
        Die Aktivitäten des Hüttenwerkes in Lasauvage wurden eingestellt, als
        die Steinkohle die Holzkohle ersetzte und die Kraft des Wassers mit
        anderen Energien nicht mehr konkurrieren konnte. (1870er Jahre) Im 20.
        Jahrhundert wurden noch Eisenerz im Tal von Lasauvage abgebaut aber in
        den Hütten von Rodange (via Dhoil und Seilbahn) und Differdingen (via
        Dhoil, Fond de Gras, Petingen) verhüttet.
      &lt;/p&gt;
    &lt;/section&gt;
    &lt;section lang="fr"&gt;
      &lt;h5&gt;La Crosnière fournissait l'énergie hydraulique à la forge de Lasauvage&lt;/h5&gt;
      &lt;p&gt;
        Dès 1623, le premier haut-fourneau de Lasauvage fonctionnait grâce à
        l'énergie hydraulique de la Crosnière: de grandes roues hydrauliques
        actionnaient les marteaux à soulèvement et les soufflets. Les premiers
        étangs de Lasauvage voyaient le jour, parce que l'eau devait être
        retenue en divers endroits. Plusieurs canaux acheminaient l'eau vers
        les roues et le rendaient au ruisseau, une fois son travail accompli.
      &lt;/p&gt;
      &lt;p&gt;
        Malgré les bassins de retenue, il pouvait y avoir pénurie d'eau, ce qui
        rendait le travail dans la forge impossible. Les ouvriers étaient
        renvoyés à la maison et ne gagnaient pas d'argent.
      &lt;/p&gt;
      &lt;p&gt;
        La forge de Lasauvage ferma ses potes dans les années 1870, lorsque la
        houille et les nouvelles énergies (la vapeur et l'électricité)
        rendaient obsolètes le charbon de bois et l'énergie hydraulique.
      &lt;/p&gt;
      &lt;p&gt;
        L'activité minière prend un grand essor au 20ième siècle et la minette
        exploitée dans la vallée de Lasauvage est fondue dans les usines de
        Rodange (via le Dhoil supérieur et le funiculaire) et de Differdange
        (via le Dhoil inférieur, le Fond de Gras et Pétange).

has different paths that can be followed, each marked with a different type of
animal. I chose to follow a mixture of them, starting with the heron-marked one
(orange on the map) and then following the bat-marked one (black on the map).
From there, I followed the stag-marked trail (green on the map) until point F,
then the boar-marked trail (yellow on the map) until point G, and then again
the stag-marked trail.&lt;/p&gt;

&lt;p&gt;The orientation map at Lasauvage was a useful reference point before heading
onto the trail.&lt;/p&gt;
&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;p&gt;From there, the trail leads through the park and over the border into France.
It continues onto a wooden pier which is built around the pond known as
&lt;em&gt;"Kiercheweier"&lt;/em&gt;, meaning &lt;em&gt;"church pond"&lt;/em&gt; in Luxembourgish. This is
explained by its location near the church named &lt;a href="https://www.stadhaus.lu/espaces/eglise-sainte-barbe"&gt;&lt;em&gt;"Église
Saint-Barbe"&lt;/em&gt;&lt;/a&gt;. The church
itself was desacralised in 2018 but is now used as an event venue by the &lt;a href="https://www.stadhaus.lu/"&gt;Aalt
Stadhaus&lt;/a&gt;, Differdange's cultural centre, where my 
&lt;a href="/blog/2026/07/hiking-log-1-circuit-korspronk/"&gt;previous trail&lt;/a&gt; started.&lt;/p&gt;
&lt;p&gt;There is also an information board which is not actually an official part of
the trail, but I took a photo anyway. It discusses the flora of the pond, the
plants you will find here, and their importance to the surrounding fauna.&lt;/p&gt;

        &lt;h5&gt;Les eaux - habitat naturel des végétaux&lt;/h5&gt;
        &lt;p&gt;
          Les eaux constituent un habitat naturel très particulier qui se
          distingue notamment par une flore typique. Selon la zone aquatique
          (étendue d'eau, marais ou zone riveraine), nous retrouvons des
          plantes qui se sont adaptées aux conditions spécifiques du milieu.
          Étant donné ce zonage, la végétation à proximité des eaux est souvent
          très riches en espèces.
        &lt;/p&gt;
        &lt;p&gt;
          La variété des espèces n'est pas seulement intéressante du point de
          vue botanique, elle offre au-delà un habitat naturel à de nombreuses
          espèces d'animaux.

          &lt;h5&gt;Végétation des marais&lt;/h5&gt;
          &lt;p&gt;&lt;strong&gt;Une riche végétation riveraine aux expèces typiques&lt;/strong&gt;&lt;/p&gt;
        &lt;/hgroup&gt;
        &lt;p&gt;
          Le «Kiercheweier» est entouré d'une luxuriante végétation, même du
          côté du ponton. Aménagée en partie après la création de l'étang, la
          végétation provient en grande partie d'une implantation naturelle.
          Les espèces typiques des rives d'eau, roselières et mégaphorbiaies,
          dominent. Elles sont adaptées aux milieux humides et souvent riches
          en éléments nutritifs et atteignent par conséquent une hauteur assez
          importante. En font partie des expèces comme: le Rubanier d'eau, la
          Massette à feuilles larges, l'Iris des marais, l'Eupatoire chanvrine,
          l'Épilobe à grandes fleurs, la Salicaire commune et la
          reine-des-prés.
        &lt;/p&gt;
      &lt;/section&gt;
      &lt;section&gt;
        &lt;hgroup&gt;
          &lt;h5&gt;Plantation semi-naturelle&lt;/h5&gt;
          &lt;p&gt;&lt;strong&gt;Les plantes ornementales mettent la végétation naturelle en valeur&lt;/strong&gt;&lt;/p&gt;
        &lt;/hgroup&gt;
        &lt;p&gt;
          La végétation riveraine est en majeure partie naturelle. Pour la
          mettre encore davantage en valeur, des vivaces décoratives,
          non-indigènes, ont été ajoutées. Il s'agit notamment du Jonc fleuri
          et de l'Aloès d'eau, qui sont des espèces européennes, ne poussant
          pas dans la nature luxembourgeoise. Des espèces comme la Grande aunée
          (Asie centrale) ou l'Oeil de boeuf (Europe du sud-est) sond de
          provenance éloignée et ont été introduites chez nous commes plantes
          vivaces de jardin. Toutes ces espèces nécessitent des sols humides à
          mouillés et prospèrent dans des conditions idéales près du
          «Kiercheweier». Tous végétaux confondus, non moins de 196 espèces
          peuplent l'étang. la plupart étant des variétés indigènes. Cette
          richesse végétale est un énomre point d'attrait pour de nombreuses
          espèces animales, sur-tout pollinisatrices.
        &lt;/p&gt;
        &lt;/section&gt;
      &lt;section&gt;
        &lt;hgroup&gt;
          &lt;h5&gt;La vie des insectes&lt;/h5&gt;
          &lt;p&gt;&lt;strong&gt;Une offre florale riche pour les papillons, les abeilles et autre pollinisateurs&lt;/strong&gt;&lt;/p&gt;
        &lt;/hgroup&gt;
        &lt;p&gt;
          Avec ses nombreuses espèces, la végétation riveraine luxuriante offre
          à longueur d'année des fleur où les pollinisateurs, comme les
          papillons, les abeilles (abeille à miel ou abeilles sauvages) ou
          autres groupes (p. ex. les syrphides) peuvent se régaler. A la
          recherche de nourriture faite de pollen ou de nectar, ils pollinisent
          les plantes et veillent ainsi à leur reproduction. Cette dépendance
          mutuelle constitue un facteur écologique important, qui joue
          également un rôle crucial dans l'alimentation de l'homme. La
          production de bon nombre d'aliments végétaux dans le monde entier
          dépend des pollinisateurs. Voilà pourquoi le déclin de nombreuses
          espèces - abeilles, papillons - doit nous alerter, dû à la
          disparition des pollinisateurs. Des plantations abondantes et variées
          dans les espaces verts privés et publiques, constituent un moyen
          idéal et simple pour lutter contre ce phénomène et faire en sorte que
          les pollinateurs trouvent à manger.
        &lt;/p&gt;
      &lt;/section&gt;

      &lt;/hgroup&gt;
      &lt;section&gt;
        &lt;h5&gt;Gewässer als Lebensraum für Pflanzen&lt;/h5&gt;
        &lt;p&gt; 
          Gewässer stellen einen ganz speziellen Lebensraum dar, der sich unter
          anderem durch eine typische Flora auszeichnet. Je nach Gewässerzone
          (Wasserbereich, Sumpfzone oder Ufer) findet man Pflanzenarten, die
          sich an die spezifischen Bedingungen angepasst ahben. Aufgrund dieser
          Zonierung findet man an Gewässern daher nicht selten eine besonders
          artenreiche Vegetation.
        &lt;/p&gt;
        &lt;p&gt;
          Diese Artenvielfat ist nicht nur aus botanischer Sicht interessant,
          sondern bietet auch gleichzeitig vielen Tierarten Lebensraum.
        &lt;/p&gt;
      &lt;/section&gt;
      &lt;section&gt;
        &lt;hgroup&gt;
          &lt;h5&gt;Sumpfvegetation:&lt;/h5&gt;
          &lt;p&gt;&lt;strong&gt;Eine artenreiche Ufervegetation mit typischen Arten&lt;/strong&gt;&lt;/p&gt;
        &lt;/hgroup&gt;
        &lt;p&gt;
          Der "Kiercheweiher" ist von einer üppigen Ufervegetation umgeben,
          selbst zur Seite des Steges. Diese wurde nach der Anlage des Weihers
          teilweise angepflanzt, hat sich aber auch zu einem großen Teil selber
          angesiedelt. Sie wird von den typischen Arten der Röhrichte und
          Hochstaudensäume längs von Gewässern geprägt. Diese sind an feuchte
          und meist nährstoffreiche Lebensbedingungen angepasst und werden oft
          relativ hochwüchsig. Hierzu gehören Arten wie Ästiger Igelkolben,
          Breitblättriger Rohrkolben, Sumpf-Schwertlilie, Wasserdost, Zottiges
          Weidenröschen, Blutweiderich und Mädesüß.
        &lt;/p&gt;
        &lt;/section&gt;
      &lt;section&gt;
        &lt;hgroup&gt;
          &lt;h5&gt;Naturnahe Bepflanzung&lt;/h5&gt;
          &lt;p&gt;&lt;strong&gt;Zierstauden werten die natürliche Vegetation optisch auf&lt;/strong&gt;&lt;/p&gt;
        &lt;/hgroup&gt;
        &lt;p&gt;
          Die Ufervegetation ist weitgehend naturnah. Um sie optisch
          aufzuwerten, wurden allerdings einige auffallende Stauden
          angepflanzt, die nicht zu unserer einheimischen Flora gehören. Hierzu
          zählen etwa Schwanenblume und Krebsschere, die zwar europäische Arten
          sind, aber natürlicherweise nicht in Luxemburg vorkommen. Arten, wie
          der Echte Alant (aus Zentralasien) oder die Große Telekie (aus
          Südosteuropa) kommen aus weiter entfernten Gegenden und werden bei
          uns als Gartenstauden angebaut. All diese Arten sind ebenfalls an
          feuchte bis nasse Standortbedingungen angepasst und gedeihen gut am
          "Kiercheweiher". Zusammen mit den einheimischen Arten konnten
          insgesamt 196 Pflanzenarten am Weiher gezählt werden, wobei die weit
          überwiegende Zahl einheimisch ist. Dieser Artenreichtum an Pflanzen
          ist auch für viele Tierarten attraktiv, insbesondere für Bestäuber.
        &lt;/p&gt;
      &lt;/section&gt;
      &lt;section&gt;
        &lt;hgroup&gt;
          &lt;h5&gt;Insektenleben&lt;/h5&gt;
          &lt;p&gt;&lt;strong&gt;Ein reiches Blütenangebot für Schmetterlinge, Bienen und andere Bestäuber&lt;/strong&gt;&lt;/p&gt;
        &lt;/hgroup&gt;
        &lt;p&gt;
          Die üppige Ufervegetation mit ihren vielen Arten, bietet über lange
          Zeiträume ein reiches Blütenangebot, das von Bestäubern, wie
          Schmetterlingen, Hausbiene, vielen Wildbienenarten, aber auch
          weiteren Gruppen wie Schwebfliegen, gerne angenommen wird. Auf der
          Suche nach Pollen oder Nektar für die eigene Ernährung bestäuben sie
          gleichzeitig die Pflanzen und sorgen so für deren Fortpflanzung.
          Diese gegenseite Abhängigkeit ist ein wichtiger ökologischer Faktor,
          der auch für alle Ernährung des Menschen eine zentrale Rolle spielt.
          Denn die Produktion vieler pflanzlicher Nahrungsmittel weltweit ist
          von Bestäubern abhängig. In diesem Zusammenhang ist der Rückgang
          vieler dieser Arten, etwa von Wildbienen, Schmetterlingen, aber auch
          der Hausbiene sehr bedenklich. Eine Rolle spielt dabei vielerorts der
          Nahrungsmangel. Üppige Pflanzenbestände auch in Gärten und
          öffentlichen Grünanlage, können dem entgegenwirken.
        &lt;/p&gt;
      &lt;/section&gt;

&lt;p&gt;As I walked along the pier, I noticed some ducks and geese, which I, of course, photographed. We will encounter the geese again later.&lt;/p&gt;

&lt;p&gt;A few steps later, I came to a second information board, which is part of the
trail, discussing the stream and its fauna. The stream's source is 400 metres
west of a place called &lt;em&gt;"Baache Jang"&lt;/em&gt;; from there, it flows into the Chiers —
you may remember this from my &lt;a href="/blog/2026/07/hiking-log-1-circuit-korspronk/"&gt;previous hiking
log&lt;/a&gt;. Apparently, before 2005,
Lasauvage's wastewater entered the Crosnière unfiltered.&lt;/p&gt;

    &lt;/hgroup&gt;
    &lt;section lang="de"&gt;
      &lt;h5&gt;Die Crosnière - ein lebendiger Bach&lt;/h5&gt;
      &lt;p&gt;
        Die Crosinère (Réierbaach) entspringt etwa 400 m westlich von Baache
        Jang und ergießt sich in die Chiers, um danach in die Maas (Meuse) zu
        fließen. Als Quellbach ist die Crosnière ein ziemlich sauberes
        Gewässer. Ab dem Jahr 2005 werden die Abwässer von Lasauvage, die
        vorher ungesäubert in den Bach flossen, geklärt. Leider findet man
        Rückstande einiger Abfallhalden im Oberlauf des Baches.
      &lt;/p&gt;
      &lt;p&gt;
        Die Tierwelt in und um die Crosnière zeigt sich mit der Wasserqualität
        zufrieden. Insbesondere Kleinlebewesen (Eintagsfliegen, Röcherfliegen,
        Bachflohkrebs, ...) die das ganze Jahr im Bach leben, sowie Fische und
        Vögel, die von diesen Insekten leben, deuten darauf hin, dass der
        Oberlauf des Baches in einem naturnahen Zustand ist.
      &lt;/p&gt;
      &lt;p&gt;
        Der Eisvogel lebt zum großen Teil von kleinen Fischen, die Wasseramsel
        spaziert Minuten lang unter Wasser, um Larven unter den Steinen heraus
        zu picken, die Gebirgsstelze fängt Wasserinsekten in allen Stadien.
        Alle drei Arten bleiben im Winter bei uns, weichen erst nach Süden aus,
        wenn die Gewässer zu frieren.
      &lt;/p&gt;
    &lt;/section&gt;
    &lt;section lang="fr"&gt;
      &lt;h5&gt;La Crosnière - un ruisseau vivant&lt;/h5&gt;
      &lt;p&gt;
        La source de la Crosnière (Réierbaach) se trouve près de Baache Jang.
        La Crosnière est un affluent de la Chiers qui se jette dans la Meuse.
        La Crosnière est un ruisseau assez propre, d'autant plus que les eaux
        résiduelles de Lasauvage sont décantées depuis 2005. Malheureusement
        les résidus de quelques décharges se mélangent aux eaux près de la
        source.
      &lt;/p&gt;
      &lt;p&gt;
        Ce qui n'empêche pas les animaux vivant à l'intérieur et à l'extérieur
        de l'eau de s'y sentir très bien. Le cours supérieur du ruisseau se
        trouve dans un état très près de l'idéal: En témoignent les
        micro-organismes tels les éphémères, les phryganes, les gammares qui y
        pullulent durant toute l'année ainsi que les poissons et les oiseaux
        qui en vivent.
      &lt;/p&gt;
      &lt;p&gt;
        Le martin-pêcheur se nourrit en grande partie des petits poissons, le
        cincle plongeur se promène pendant plusieurs minutes sous l'eau pour
        piquer des larves en-dessous des pierres, la bergeronnette attrape des
        insectes aquatiques dans tous les stades de développement. Ces trois
        espèces hivernent chez nous et ne partent vers les régions moins
        froides qu'au cas où la surface de l'eau gèle.

&lt;figcaption&gt;
&lt;p&gt;Here the trail enters the Kiemerchen – Scheiergronn – Groussebësch protected area.&lt;/p&gt;
&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;p&gt;The trail follows the stream until it reaches the entrance to the forest, which
is marked by a sign indicating that it is a designated nature reserve named
&lt;em&gt;"Kiemerchen - Scheiergronn - Groussebësch"&lt;/em&gt;. As soon as I entered the forest, I
loved the cooling sensation on my skin and the refreshing air.&lt;/p&gt;
&lt;p&gt;The path then leads past an information board about floodplain forests. As the
Crosnière is very narrow, only a small part of the surrounding forest is
considered a floodplain forest. The board also discusses the types of trees
that can be seen here and describes how the &lt;a href="https://en.wikipedia.org/wiki/Salix_viminalis"&gt;basket
willow&lt;/a&gt; has been shaped by human
cultivation.&lt;/p&gt;
&lt;p&gt;The trail then leads past a ruin. From the outside, it is impossible to tell
what the building was originally used for, but according to OpenStreetMap, it
used to be a power station. Not far away, I also saw the entrance to the old
Lasauvage mine.&lt;/p&gt;

      &lt;h5&gt;Der Auenwald&lt;/h5&gt;
      &lt;p&gt;
        Auenwälder entstehen an Bächen und im Überflutungsbereich der Gewässer.
        Das Tal der Crosnière ist sehr eng und der Auenbereich beschränkt sich
        somit auf die beiden Randstreifen des Baches. Typische Bäume des
        Auenwaldes sind: Erlen, Eschen, Ulmen (Harthhölzer), Weiden,
        Zitterpappeln (Weichhölzer).
      &lt;/p&gt;
      &lt;p&gt;
        Weiden finden wir an den verschiedenen Abschnitten des Tales:
        Korbweide, Silberweide, Bruchweide, Salweide, Purpurweide&lt;br&gt; Die
        Korbweide ist eine Schnittform der verschiedenen Weiden, die der Mensch
        gestaltet hat. Viele kleinere Pflanzen fühlen sich woch am Bachrand:
        Milzkraut, Wasserminze, Bittersüsser Nachtschatten, Gilbweiderich ...
      &lt;/p&gt;
      &lt;p&gt;
        Begleitvegetation an Bächen ist wichtig für die Befestigung der Ufer,
        die Beschattung des Bachess, Niststätte für Tiere, die Gestaltung des
        Landschaftsbildes. Der Grund des Baches ist mitbestimmend für die
        Vegetation, aber auch für die Laichmöglichkeiten der Fische und die
        Entwicklung von Kleinstlebewesen (z.B. Eintagsfliegen, Köcherfliegen,
        Bachflohkrebse)
      &lt;/p&gt;
    &lt;/section&gt;
    &lt;section lang="fr"&gt;
      &lt;h5&gt;La forêt riveraine&lt;/h5&gt;
      &lt;p&gt;
        Les bordures et les zones d'inondation des ruisseaux donnent naissance
        aux forêts riveraines. Comme la vallée de la Crosnière est très
        étroite, la forêt riveraine se limite aux seules bandes de la rive.
      &lt;/p&gt;
      &lt;p&gt;
        Les aulnes, les frênes, les ormes au bois dur ainsi que les saules et
        les trembles au bois tendre sont les arbres typiques de la forêt
        riveraine. On peut voir différentes espèces de saules le long du cours
        d'eau: le saule blanc, le saule fragile, le saule marsault, le saule
        pourpre.&lt;br&gt; En croisant différentes espèces des saules, l'homme a créé
        l'osier (seule têtard).
      &lt;/p&gt;
      &lt;p&gt;
        Beaucoup de petites plantes aiment les bandes de rive: le dorine, la
        menthe aquatique, la douce-amère, la lysimaque commune...&lt;br&gt; Toutes
        ces plantes jouent un rôle important. Elles retiennent la rive,
        ombragent le ruisseau, façonnent le paysage et fournissent des nichoirs
        aux animaux.
      &lt;/p&gt;
      &lt;p&gt;
        La végétation, le frai des poissons, le développement des
        micro-organismes comme les larves d'éphémères, larves de phrygane et
        les gammares dépendent en grande partie du fond du ruisseau, de la
        propreté et de la teneur en oxygène de l'eau.
      &lt;/p&gt;

    &lt;/p&gt;
  &lt;/blockquote&gt;
&lt;/details&gt;&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;h3 id="taking-a-wrong-turn-and-obstacles-in-the-way"&gt;Taking a wrong turn and obstacles in the way&lt;/h3&gt;&lt;p&gt;After passing the mine, the trail began to ascend, which I could also tell from
my increasing heart rate. At the point marked F on the map, I remembered that
the &lt;a href="https://www.visitluxembourg.com/tour/local-trail-sentier-de-la-crosniere"&gt;VisitLuxembourg
website&lt;/a&gt;
said to follow the stag sign. However, when I looked at my GPS, I realised that
I had gone off the trail. Fortunately, I hadn't gone too far, so I backtracked
to point F and then followed the trail as marked on my GPS.&lt;/p&gt;
&lt;p&gt;Looking at it again, I notice that the official trail on the website is a
mixture of the paths I described earlier rather than following a single animal
marker.&lt;/p&gt;
&lt;p&gt;Upon reaching the summit of the trail, I continued along it, which led to some
obstacles. There was a fallen tree on the trail, so I stopped for a few seconds
to analyse the situation and decide on the best way to tackle it without
hurting myself. At this point, I wished I had already bought some hiking shoes,
as this would have made the adventure a little less risky.&lt;/p&gt;
&lt;p&gt;As luck would have it, a few dozen metres after the first fallen tree, I came
to a second one, which was smaller and easier to get over. I have, of course,
already informed the local forester, and I hope that the fallen trees have been
cleared away and the trail made safe again.&lt;/p&gt;

&lt;h3 id="the-return-of-the-geese"&gt;The return of the geese&lt;/h3&gt;&lt;p&gt;I then started the descent of the trail very carefully, despite not wearing
hiking shoes. I passed a small pond again and continued along the same path out
of the forest. When I arrived at the &lt;em&gt;"Kiercheweier"&lt;/em&gt;, my friends the geese had
made their way into the park. They did not seem to be afraid of me, so I took
some photos of them as they came quite close before heading back into the pond.&lt;/p&gt;

&lt;h3 id="looking-back-at-the-trail"&gt;Looking back at the trail&lt;/h3&gt;&lt;p&gt;I found this trail well suited to an evening walk, except for the unforeseen
obstacles in the way. I especially liked the section around the
&lt;em&gt;"Kiercheweier"&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Would I recommend coming to Lasauvage just to do this trail? No, but if you're
in the Lasauvage area, for example visiting the &lt;a href="https://www.visitluxembourg.com/place/eugene-pesch-museum-lasauvage"&gt;Eugène Pesch
Museum&lt;/a&gt; or
near the &lt;a href="https://www.visitluxembourg.com/place/minett-park-fond-de-gras"&gt;Minett Park
Fond-de-Gras&lt;/a&gt;,
you could fit it in. Or, if you're staying in the &lt;a href="https://www.visitluxembourg.com/hostel-and-rental/kabaischen-la-sauvage"&gt;Kabaisercher: La
Sauvage&lt;/a&gt;
and want to go for an evening walk, then yes, you should do it.&lt;/p&gt;
&lt;p&gt;All in all, my Wanderlust was sated for the evening. But knowing Wanderlust,
probably not for long.&lt;/p&gt;

It all started with the recent
&lt;a href="https://en.wikipedia.org/wiki/2026_European_heatwaves#Luxembourg"&gt;heatwave&lt;/a&gt;.
To cool down a bit, I started going outside in the evening. I had my old &lt;a href="https://www.garmin.com/en-US/p/156873/"&gt;GPS
handheld&lt;/a&gt; lying around, so I thought
I'd use it again to track my walks. As luck would have it, the rubber on the
power button deteriorated after a few days of use, making the device impossible
to power on or off and thus unusable. I tried to find a replacement, but none
were available. This prompted me to buy a new device: the &lt;a href="https://www.garmin.com/fr-FR/p/1326077/"&gt;Garmin eTrex
Touch&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;After exploring my new town by going on some impromptu walks and getting to
know my new device a little better, I thought: what better way to spend the day
than doing some short local hikes? As I knew nothing about them, I asked
myself where I could find some information.&lt;/p&gt;
&lt;h3 id="finding-a-trail-without-app-lock-in"&gt;Finding a trail without app lock-in&lt;/h3&gt;&lt;p&gt;As I would like to be &lt;a href="/blog/2026/06/back-to-blogging/"&gt;more digitally
independent&lt;/a&gt;, one of my requirements is the
ability to download a &lt;a href="https://en.wikipedia.org/wiki/GPS_Exchange_Format"&gt;GPX&lt;/a&gt;
or similar track. Secondly, I don't want to be bound to an app or service
provider. I therefore wanted to avoid making a particular app or online service
an essential part of finding and following a trail. Apps such as
&lt;a href="https://www.komoot.com/"&gt;Komoot&lt;/a&gt; or &lt;a href="https://www.wikiloc.com/"&gt;Wikiloc&lt;/a&gt; are
out of the question.&lt;/p&gt;
&lt;p&gt;For geographical data in Luxembourg, my go-to place is &lt;a href="https://www.geoportail.lu/en/"&gt;the national geoportal
of the Grand-Duchy of Luxembourg&lt;/a&gt;, also known as
&lt;em&gt;"Geoportail"&lt;/em&gt;. Yes, it has details on all &lt;a href="https://map.geoportail.lu/theme/tourisme?version=3&amp;amp;lang=fr&amp;amp;X=667917&amp;amp;Y=6394482&amp;amp;zoom=9&amp;amp;rotation=0&amp;amp;features&amp;amp;map_id=9b7d8e482adb422ba491ecde4f845e2f&amp;amp;layers=2811-667&amp;amp;opacities=1-1&amp;amp;time=--&amp;amp;bgLayer=topomap"&gt;hiking
trails&lt;/a&gt;.
The only disadvantage is that I cannot filter them by length or difficulty.&lt;/p&gt;
&lt;p&gt;This prompted me to do some more research, which led me to &lt;a href="https://wwl.lu/index.php/en/wwl-homepage"&gt;Wanderweeër
Lëtzebuerg (WWL)&lt;/a&gt;, an independent
project run by a Luxembourgish hiking enthusiast.
&lt;a href="https://wwl.lu/index.php/en/hiking-trails"&gt;Here&lt;/a&gt;, we can filter trails by
keyword, category, distance and difficulty. I looked around to find an easy,
short local hike and found the &lt;em&gt;"Circuit Korspronk"&lt;/em&gt;.&lt;/p&gt;

&lt;h3 id="why-i-chose-circuit-korspronk"&gt;Why I chose &lt;em&gt;"Circuit Korspronk"&lt;/em&gt;&lt;/h3&gt;&lt;p&gt;The &lt;a href="https://www.visitluxembourg.com/tour/local-hiking-trail-df-1-circuit-korspronk-differdange"&gt;Visit Luxembourg
website&lt;/a&gt;
presents &lt;em&gt;"Circuit Korspronk"&lt;/em&gt; as a journey to the modest beginning of a much
longer river. Starting near the centre of Differdange, the circular trail
climbs through fields and shaded woodlands to the source of the Kor, the local
name for the Chiers, which flows on through Belgium and France. The combination
of nature, local history, and its manageable length made it seem like an ideal
choice for my first local hike.&lt;/p&gt;
&lt;p&gt;Bearing this in mind, I loaded the trail and parking POI onto my GPS handheld,
packed some water and fruit, and set off on a sunny Friday afternoon to
complete my first local hike.&lt;/p&gt;
&lt;h3 id="elevation-is-not-everything"&gt;Elevation is not everything&lt;/h3&gt;&lt;figure class="w33 left"&gt;
&lt;img src="/blog/2026/07/hiking-log-1-circuit-korspronk/wooden-post-korspronk.jpg" alt="A wooden signpost stands in a leafy forest, pointing to the right towards &amp;quot;Korspronk&amp;quot;, with &amp;quot;Déifferdenger Geschichtsfrënn 2008&amp;quot; written below."&gt;
&lt;figcaption&gt;
&lt;p&gt;The wooden sign pointing towards the source of the &lt;em&gt;"Kor"&lt;/em&gt; bears the name
"Déifferdenger Geschichtsfrënn" (literally the "Friends of Differdange History")
and the year 2008.&lt;/p&gt;
&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;p&gt;The trail begins near the &lt;a href="https://www.stadhaus.lu/"&gt;Aalt Stadhaus&lt;/a&gt;, the former
city hall which is now a cultural centre. It also houses the local library and
music school and functions as a local theatre. Very close by is the
current city hall, which is being demolished &lt;a href="https://infos.rtl.lu/news/luxembourg/la-mairie-de-differdange-devait-etre-renovee-elle-va-etre-rasee-1177784037"&gt;due to construction defects and
structural
problems&lt;/a&gt;
and will need to be rebuilt.&lt;/p&gt;
&lt;p&gt;From there, the trail goes up &lt;em&gt;"Rue Metzkimmert"&lt;/em&gt;, which was quite an ordeal
for an untrained hiker like me — I could really feel it in my heart rate! This
showed me that elevation is not everything; the slope clearly plays a role
too. After this steep ascent, the trail enters the shady woods, where the
air felt noticeably cooler than the air in town. The change was immediately
refreshing.&lt;/p&gt;
&lt;p&gt;I followed the trail to an open area with a picnic table, then passed the
shooting range in Oberkorn before returning to the woods. Continuing, I
arrived at a set of wooden stairs and the main attraction and namesake of this
trail: the source of the river &lt;a href="https://en.wikipedia.org/wiki/Chiers"&gt;Chiers&lt;/a&gt;,
or in Luxembourgish &lt;em&gt;"Kor"&lt;/em&gt;.&lt;/p&gt;
&lt;div class="clear"&gt;&lt;/div&gt;&lt;h3 id="what-the-information-panels-taught-me"&gt;What the information panels taught me&lt;/h3&gt;&lt;figure class="w25 right"&gt;
&lt;img src="/blog/2026/07/hiking-log-1-circuit-korspronk/metal-plate-haaptquell-vun-der-kor.jpg" alt="A weathered metal information panel at Korspronk with a painted map showing the rivers Chiers, Meuse, Othain and Crusnes above Luxembourgish text."&gt;
&lt;figcaption&gt;
&lt;p&gt;The information panel next to the spring.&lt;/p&gt;
&lt;/figcaption&gt;
&lt;/figure&gt;
&lt;p&gt;A nearby metal panel provides information about the &lt;em&gt;"Kor"&lt;/em&gt;. According to the
information panel, the source lies 352 metres above sea level and the river
is 122 kilometres long. From Differdange, the &lt;em&gt;"Kor"&lt;/em&gt; flows through the
&lt;em&gt;"Kordall"&lt;/em&gt; valley before continuing through Belgium and France and eventually
joining the &lt;a href="https://en.wikipedia.org/wiki/Meuse"&gt;Meuse&lt;/a&gt; in
&lt;a href="https://en.wikipedia.org/wiki/Sedan,_Ardennes"&gt;Sedan&lt;/a&gt;, a commune in France.&lt;/p&gt;
&lt;p&gt;I actually learnt something new here! There are four towns that contain the
river's Luxembourgish name:
&lt;a href="https://en.wikipedia.org/wiki/Oberkorn"&gt;&lt;em&gt;"Uewerkuer"&lt;/em&gt;&lt;/a&gt;,
&lt;a href="https://en.wikipedia.org/wiki/Niederkorn"&gt;&lt;em&gt;"Niederkuer"&lt;/em&gt;&lt;/a&gt;,
&lt;a href="https://en.wikipedia.org/wiki/Bascharage"&gt;&lt;em&gt;"Nidderkäerjeng"&lt;/em&gt;&lt;/a&gt;, and
&lt;a href="https://en.wikipedia.org/wiki/Hautcharage"&gt;&lt;em&gt;"Uewerkäerjeng"&lt;/em&gt;&lt;/a&gt;. More
information about the names can be found on a later information board. The
board proposes that the name &lt;em&gt;"Kor"&lt;/em&gt; derives from &lt;em&gt;"Kar"&lt;/em&gt;, a pre-Celtic word
associated with water, streams or marshland. It also connects the later French
name &lt;em&gt;"Chiers"&lt;/em&gt; with &lt;em&gt;"cher"&lt;/em&gt; and the Latin word
&lt;a href="https://en.wiktionary.org/wiki/carus"&gt;&lt;em&gt;"carus"&lt;/em&gt;&lt;/a&gt;. I have not been able to
verify this proposed etymology independently, but it is an intriguing example
of how local place names can preserve older layers of language.&lt;/p&gt;
&lt;p&gt;Interestingly, the spring is located halfway along the trail. It is surrounded
by concrete, so I could only see where the water flows out. There is also a
bench here. It's a nice place to relax. Unfortunately, I forgot to take a good
photo.&lt;/p&gt;
&lt;p&gt;Continuing along the trail, I left the woods behind me and walked alongside
some fields, crossing a bridge over the train tracks. I then entered the town of
&lt;em&gt;"Uewerkuer"&lt;/em&gt;, passing under the train station and some allotment gardens,
before reaching the cemetery of Differdange and arriving back at the start of
the trail.&lt;/p&gt;
&lt;h3 id="a-question-about-hiking-gear"&gt;A question about hiking gear&lt;/h3&gt;&lt;p&gt;At the moment, I carry a water bottle in my backpack. Taking the backpack off
every time I want a drink is inconvenient, especially when my back is already
warm and sweaty. I am therefore considering either a hydration reservoir, such
as the &lt;a href="https://www.asadventure.com/en/p/camelbak-hydration-reservoir-crux-1-5l-reservoir-2323C70002.html?colour=2374"&gt;CamelBak
Crux&lt;/a&gt;,
or an &lt;a href="https://www.hydrolid.com/"&gt;adapter&lt;/a&gt; that adds a drinking tube to an
ordinary bottle.&lt;/p&gt;
&lt;p&gt;This is where you come in! I'd love to hear your opinions, suggestions or ideas
on this. You can simply write to me on
&lt;a href="https://social.dennisfink.me/@me"&gt;Mastodon&lt;/a&gt; or email me—you will find my
email address in the footer of this blog.&lt;/p&gt;
&lt;h3 id="the-beginning-of-a-new-habit"&gt;The beginning of a new habit&lt;/h3&gt;&lt;p&gt;In my opinion, this trail has its ups and downs. The beginning can be quite
exhausting if one is not fit, but as soon as I entered the woods, I felt as though I had
left urban life far behind me. The source of the river is
a very pleasant place and definitely the highlight of the trail. The final section was less memorable; in particular, the walk through the town
of &lt;em&gt;"Uewerkuer"&lt;/em&gt; and past the cemetery of Differdange was not very interesting.&lt;/p&gt;
&lt;p&gt;This trail really ignited my
&lt;a href="https://en.wikipedia.org/wiki/Wanderlust"&gt;wanderlust&lt;/a&gt;. Since then, I have done
several others, which I will document in the future. I already feel that hiking
helps me to switch off for a few moments by simply taking in the fresh air and
paying attention to the beautiful, intricate, and sometimes mysterious natural world
around me.&lt;/p&gt;

Yes, it's time to get back to basics again. But why
now? There are several reasons for this, which I may discuss in more detail in
future posts. For now, let me recap on two things.&lt;/p&gt;
&lt;p&gt;Firstly, the recent rise of the &lt;a href="https://di.day/en"&gt;"Digital Independence Day"&lt;/a&gt;
events in Germany, has inspired me to become even more digitally independent.
Since joining the &lt;a href="https://c3l.lu"&gt;local Chaos Computer Club&lt;/a&gt; over 15 years
ago, I have been on a mission to leave big tech behind. This has led me to
self-host most of my digital tools and start blogging again.&lt;/p&gt;
&lt;p&gt;The main reason, though, is that the web is fundamentally about sharing
information, not just consuming it. At a time when content generated by LLMs
seems to dominate the web, it's more important than ever to have content
written by humans. This is my attempt to contribute to this. I may blog about
my views on AI in the future.&lt;/p&gt;
&lt;p&gt;What can you find here? As I write on the &lt;a href="/about/"&gt;"About" page&lt;/a&gt;:&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;This blog is my place to capture my thoughts before they disappear. It'll most
likely include little things from my day-to-day life, things I've been reading
about and recurring ideas, as well as the occasional rabbit hole I've fallen
down. There won't be a theme or a schedule, but it will be a space where I can
collect all the things that I find interesting and share them with you.&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;Thank you for reading my blog, and I hope to see you again soon! You might want to subscribe to the &lt;a href="/blog/latest.xml"&gt;Atom feed&lt;/a&gt;!&lt;/p&gt;
