Acet'eau - Rivière souterraine de St-Christophe/Roc

Circuit of the underground river, 4,3 km long, accessible by the well of Chiloup at La Chapelle Bâton with abseiling and exit at the Lavoir de la Roche at 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. On the other hand, in winter, their important clogging often transforms them into ponds or bodies of water.
Comfortable sportswear with boots or sneakers (old) + a change of clothes.
