Getting to Nommern by public transport

On this short hiking trail, you reach one of the geological highlights of the region: the rock formation called Champignon. It is a free-standing rock block shaped like a mushroom. This shape was naturally created by weathering processes. The trail initially leads through the forest with slight ascents and descents. The final section goes over open land back to the starting point. The route is not stroller-friendly, as there are some stairs going down in the first half.

The hiking trail leads from the starting point to the right towards Rue de l’Eau. There is an approximately 1.2 km long ascent that ends on a forest path. Along the way, you can admire the typical sandstone rock formations of the Noumerleeën. At the top, the path turns left to a chapel with a beautiful statue of the Virgin Mary. From there, it continues down a narrow forest path through a small canyon back to the starting point.

Explore the Mullerthal – Luxembourg’s Little Switzerland – by bike, using the regional bicycle hire scheme, RentaBike Mëllerdall. Bicycles are available from partners in the tourism industry, ranging from local authorities and shops to campsites. They can be hired out from, and returned to, any partner, regardless of where you collected them from. The hire cost includes a free repair service.

The probably largest mushroom in Luxembourg's Little Switzerland, is indeed not edible, but it is even more impressive: The "Champignon" is a standalone block of Luxembourg sandstone. The rock owes its shape to the various properties of individual sandstone layers that make it up: a solid, less eroded sandstone layer forms the hat, the foot consists of layers that are easier to remove. It is a weathering remnant of the sandstone layer that was deposited in the time of the Lias about 200 million years ago and originally extended further north. Today you have a fantastic view of the upstream, hilly Mergellandschaft in this direction whose rocks were formed in the Keuper period 210 to 230 million years ago. In the surroundings of the "Champignon" there are sandstone blocks with traces of human use. These include well visible grinding grooves created by people grinding their stone tools on the sandstone. It is disputed whether some of the signs and hollows served mythical purposes. The flora around the rock is also a very special: The thin nutrient-poor and dry sand cover of the soil is the rare habitat of a sandy dry grass, which is interspersed with heather. The champignon can be hiked from Nommern on the 5.2 km long local hiking trail N4. Closest bus stop: Aechelbur (500m) Closest parking lot: on site Hike: N4 (5,2 km)
