The main shaft, a 100-metre vertical drop, leads to the underground Sorgue, which can be followed upstream and downstream, with parallel rigged shafts offering a view of the great shaft.
Description
Morphology
The main shaft is a 100-metre vertical drop. Parallel rigged shafts (P21, R5, P12, R6, P9, P33) also allow descent and, via balconies, give a fine view of the atmosphere of the great shaft.
Hydrology
At the bottom of the main shaft flows the underground Sorgue. The river can be followed for a few tens of metres upstream and downstream.
Progression
One can descend via the parallel rigged shafts (P21, R5, P12, R6, P9, P33). If 2 teams are formed, one can descend via the small shafts and ascend via the P100, or vice versa; in this case, bring the equipment to rig the parallel shafts.
