Gouffre Berger, Pit cave system in Engins, France
Gouffre Berger is a limestone cave system with eleven entrances distributed across the Vercors Plateau in the French Alps. The passages extend downward through the mountain, connecting different underground chambers and channels.
The cave system was discovered in 1953 by Joseph Berger and his team, holding the title of the world's deepest cave until 1964. Its connection to another cave system in 1990 transformed it into a far more extensive underground network.
The cave network attracts international speleologists and researchers who document its geological formations and conduct scientific studies throughout the year.
Exploring this cave system requires advanced caving skills and specialized equipment due to the challenging nature of the passages. Water levels can rise rapidly, so checking weather conditions and safety guidance before visiting is essential.
The connection with Scialet de la Fromagère in 1990 extended the cave system to a depth of 1,271 meters beneath the surface.
