Rivière souterraine de Saint Christophe Sur Roc

Underground river circuit 4.3 km long, accessible via the Chiloup well at La Chapelle Bâton with abseiling and exit at Lavoir de la Roche in ST-CHRISTOPHE-SUR-ROC. It was discovered in 1975. This river is located in a triangle: ST-CHRISTOPHE-SUR-ROC/LA CHAPELLE BATON/SAINT PROJET and is fed on the one hand by rainwater infiltrating the limestone layers and on the other hand by runoff water flowing into the chasms. In summer, most of these chasms look like dry sinkholes. In winter, however, their extensive sealing often transforms them into ponds or bodies of water Comfortable sportswear with (old) boots or sneakers + a change of full gear.
