The Rocher du Chalice, located not far from the Plan Incliné in the charming town of Saint-Louis, is a natural spectacle not to be missed. Nestled in the middle of the forest, this fascinating rock is a living witness to the natural erosion that has shaped the territory over the years. Its particular shape invites visitors to give free rein to their imagination, discovering various shapes, animals, faces and engravings sculpted by natural elements.
To discover it, a walk is essential. From the Luge du Plan Incliné car park, follow the yellow dot markings for a distance of 1.2 km towards the Rocher du Chalice. The approach is via a path then a steep path, offering a little adventure before even reaching the rock. And the exploration doesn't stop there. You can extend your hike through several unusual underground passages, then via the Vallée des Éclusiers and Hofmuhl, before returning to the starting point, for a total circuit of 11.4 km.
