This simple visit, lasting from 1:30 to 2:00, consists of the descent of the well of Clairlieu (38 m) equipped every 3 m of bearings connected to each other by fixed ladders, followed by a round trip in the gallery. The presence of water and the spacing of the ladder bars limit the age of the visitors.

From the age of 12.
The visit is quite sporty (good physical condition necessary) and rather aquatic.
In addition, a crossing is also planned with a descent on rope through a 65 m well.
