I recently started hiking some local trails. It all started with the recent
[heatwave](https://en.wikipedia.org/wiki/2026_European_heatwaves#Luxembourg).
To cool down a bit, I started going outside in the evening. I had my old [GPS
handheld](https://www.garmin.com/en-US/p/156873/) 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 [Garmin eTrex
Touch](https://www.garmin.com/fr-FR/p/1326077/).
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.
# Finding a trail without app lock-in
As I would like to be [more digitally
independent](/blog/2026/06/back-to-blogging/), one of my requirements is the
ability to download a [GPX](https://en.wikipedia.org/wiki/GPS_Exchange_Format)
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
[Komoot](https://www.komoot.com/) or [Wikiloc](https://www.wikiloc.com/) are
out of the question.
For geographical data in Luxembourg, my go-to place is [the national geoportal
of the Grand-Duchy of Luxembourg](https://www.geoportail.lu/en/), also known as
_"Geoportail"_. Yes, it has details on all [hiking
trails](https://map.geoportail.lu/theme/tourisme?version=3&lang=fr&X=667917&Y=6394482&zoom=9&rotation=0&features&map_id=9b7d8e482adb422ba491ecde4f845e2f&layers=2811-667&opacities=1-1&time=--&bgLayer=topomap).
The only disadvantage is that I cannot filter them by length or difficulty.
This prompted me to do some more research, which led me to [Wanderweeër
Lëtzebuerg (WWL)](https://wwl.lu/index.php/en/wwl-homepage), an independent
project run by a Luxembourgish hiking enthusiast.
[Here](https://wwl.lu/index.php/en/hiking-trails), we can filter trails by
keyword, category, distance and difficulty. I looked around to find an easy,
short local hike and found the _"Circuit Korspronk"_.

# Why I chose _"Circuit Korspronk"_
The [Visit Luxembourg
website](https://www.visitluxembourg.com/tour/local-hiking-trail-df-1-circuit-korspronk-differdange)
presents _"Circuit Korspronk"_ 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.
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.
# Elevation is not everything
:::figure w33 left
The wooden sign pointing towards the source of the _"Kor"_ bears the name
"Déifferdenger Geschichtsfrënn" (literally the "Friends of Differdange History")
and the year 2008.
:::
The trail begins near the [Aalt Stadhaus](https://www.stadhaus.lu/), 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 [due to construction defects and
structural
problems](https://infos.rtl.lu/news/luxembourg/la-mairie-de-differdange-devait-etre-renovee-elle-va-etre-rasee-1177784037)
and will need to be rebuilt.
From there, the trail goes up _"Rue Metzkimmert"_, 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.
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 [Chiers](https://en.wikipedia.org/wiki/Chiers),
or in Luxembourgish _"Kor"_.

# What the information panels taught me
:::figure w25 right
The information panel next to the spring.
:::
A nearby metal panel provides information about the _"Kor"_. According to the
information panel, the source lies 352 metres above sea level and the river
is 122 kilometres long. From Differdange, the _"Kor"_ flows through the
_"Kordall"_ valley before continuing through Belgium and France and eventually
joining the [Meuse](https://en.wikipedia.org/wiki/Meuse) in
[Sedan](https://en.wikipedia.org/wiki/Sedan,_Ardennes), a commune in France.
I actually learnt something new here! There are four towns that contain the
river's Luxembourgish name:
[_"Uewerkuer"_](https://en.wikipedia.org/wiki/Oberkorn),
[_"Niederkuer"_](https://en.wikipedia.org/wiki/Niederkorn),
[_"Nidderkäerjeng"_](https://en.wikipedia.org/wiki/Bascharage), and
[_"Uewerkäerjeng"_](https://en.wikipedia.org/wiki/Hautcharage). More
information about the names can be found on a later information board. The
board proposes that the name _"Kor"_ derives from _"Kar"_, a pre-Celtic word
associated with water, streams or marshland. It also connects the later French
name _"Chiers"_ with _"cher"_ and the Latin word
[_"carus"_](https://en.wiktionary.org/wiki/carus). 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.
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.
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
_"Uewerkuer"_, passing under the train station and some allotment gardens,
before reaching the cemetery of Differdange and arriving back at the start of
the trail.
# A question about hiking gear
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 [CamelBak
Crux](https://www.asadventure.com/en/p/camelbak-hydration-reservoir-crux-1-5l-reservoir-2323C70002.html?colour=2374),
or an [adapter](https://www.hydrolid.com/) that adds a drinking tube to an
ordinary bottle.
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
[Mastodon](https://social.dennisfink.me/@me) or email me—you will find my
email address in the footer of this blog.
# The beginning of a new habit
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 _"Uewerkuer"_ and past the cemetery of Differdange was not very interesting.
This trail really ignited my
[wanderlust](https://en.wikipedia.org/wiki/Wanderlust). 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.
