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.

The hiking route initially leads from the starting point to the right towards Camping Nommerlayen. Before the campsite, the path leads left uphill. After about 300 meters, turn left where a longer ascent awaits. After crossing the road to Larochette, you reach the highest point of the hiking route. Afterwards, it goes downhill again on a forest path back to the starting point. Part of the hike follows the route of the former Jhangli narrow-gauge railway, which was used from 1882-1948.
