Consdorf, where the Mullerthal's rocks open into tunnels

On the map Consdorf is just a quiet village ringed by forest. What earns it a place on a Mullerthal itinerary is hidden a short walk from the houses, and visitluxembourg counts it among the region’s main hiking bases for one reason. Here you don’t only look at the rocks, you walk through them.

Seven localities on the edge of the rock country

Consdorf’s 2,093 residents in January 2026, as STATEC counts them, live in seven localities, Consdorf, Breidweiler, Colbette, Marscherwald, Michelshof, Scheidgen and Wolper. Walkers will hear most about Scheidgen, because Route 2 of the Mullerthal Trail goes right through the village and the Trail website suggests it as a base with accommodation.

Why the Kuelscheier is worth a detour

It’s a corridor about 100 m long that opened up when blocks of sandstone split away from the cliff along cracks. The roof is rock, the inside is dark, and some sections are so tight that only one-way traffic works. Below the rocks a spring rises exactly where porous sandstone sits on clay-rich marl, which is the geological secret of the whole Mullerthal. The name means coal barn, since visitluxembourg says coal from the area was probably kept here for a while. It has its own page, the Kuelscheier, with how to get there and what to bring.

The Rittergang and the Déiwepëtz are two more squeezes nearby. The Trail website warns that neither can be bypassed, which is worth knowing before you set off with anyone who hates confined spaces.

Walking to the Schiessentümpel

Consdorf’s local circuit, 9.3 km and around four hours, links two old mills, the Konsdrëfermillen in Consdorf and the Heringer Millen in Müllerthal. On the way it passes rocks named from legends, such as Goldkaul, Goldfralee, Eilebuerg, Schelmelee and Ramelee, and the Schiessentümpel waterfall, whose bridge marks the boundary with Waldbillig. If the Kuelscheier is all you want, path C2 covers it in 4.2 km.

I’d walk it from Consdorf towards Müllerthal and stop for lunch at the Heringer Millen at the far end.

There’s one corner of the commune few people place in Consdorf. The Kallektuffquell, the limestone tufa spring of the Black Ernz valley, lies within Breidweiler, and you reach it on the timber boardwalk of Trail Route 3 or along path W7 from the Heringer Millen. If you’ve had lunch there, it makes the best end to the afternoon in my view.

With children

This is one of the more family-minded corners of the region. visitluxembourg lists a guided children’s hike to the Kuelscheier and a family discovery trail at the same spot, and there’s a crazy golf course beside the tourist office. For primary-age kids a torchlit trip through the Kuelscheier is a proper adventure that doesn’t take long, and path C2 is short enough to end without complaints.

Getting there and staying

You can reach Consdorf from the capital, or from Findel airport, on buses that charge no fare. The tourist office is at 33 rue Burgkapp, beside La Pinède campsite. STATEC counted one hotel and two campsites in 2025. For more choice, Berdorf is next door on Route 2, and for a gentler, more farmland side of the Mullerthal, look at Bech.
