Beneath your feet is one of the largest subterranean networks of the Vercors, that of the Gouffre Berger. His discovery in 1953 by J. Berger led to a formidable human adventure which led in 1956 to the crossing of the coast -1000 meters, the first of the world speleology. The adventure is not over because the connection with the Cuves of Sassenage is always actively sought!
