Description

This cave is characterised by big chambers, between 30 and 50m high. This enormous chambers are the reason why it contains the characteristic  Palm Trunc Stalagmites. This enormous cave system has a natural entrance, a deep pit close to the village Orgnac, called le trou du Bertras (the hole of Bertras). So it is easy to understand, why the cave later was called Aven d'Orgnac (Abyss of Orgnac).

The cave is a major tourist attraction of the area and has an enormous amount of visitors (100.000 per years). The whole entrance area is designed to allow further visits and informations. There is the regional Musée Régional de Préhistoire (Regional prehistoric museum) and a geologic exhibition, a pedagogic center for visiting school classes, and of course a cafe and a shop.

The cave development was a bit difficult, as the cave is originally a deep pit. The paths are at the floor of the cave, at a level up to 121m below surface. The cave is entered through a long tunnel leading down to the floor of the Entrance Hall. The tours descend step by step by walking from chamber to chamber to a depth of 121m. Finally an elevator brings visitors back to the surface in less than a minute.

The tour starts in the entrance hall at the foot of the cave wall, where the tunel ends. In front is a huge pile of debris, which connsists of rocks and animal bones. The rocks are eroded from the entrance shaft above, especially by frost, and the animals entered the cave involuntarly by accident. The animals included deer....

The path leads clockwise around the hall to the other end, through typical stalagmites formed like piles of pancakes. Of course, the French call them piles of crepes. This form is a kind of  Palm Trunc Stalagmite. It is a result of the height of the ceiling, soo with changing height of the ceiling the form of the stalagmites changes too. The central stalagmite is called Pine Cone, 20 meters high with petal like layers.
