Trail of the three rocks

" Immersion in the heart of an ocean of forest, an exotic hike to discover impressive sandstone rocks and superb panoramas. "

The geological movements of the deformation of the Vosges caused the separation of whole sandstone compartments, creating faults and diaclases, zones of weakness in which the water of infiltration infiltrates, which enlarges these cracks and causes the detachment of whole sections of rocks that run down the slopes. The sandstone compartments remaining in place form beautiful ruiniform pitons with vertical or overhanging walls with a slab of conglomerates at their summits.
