Gouffre de la Cornelle de la Bauche

The entrance is Un P5 that opens against a rocky barrier. a 10-metre pit follows, then a room of 7m x 5m. The P5 and P14 follow one another. The start of the P30 is moderately narrow (helmet sideways). The P48 offers a very fine 45 m length. What follows is Un P10 that allows reaching the former selective squeeze, bypassed by blasting in 2024, before a series of pits leading to the salle des Merveilles.

At the base of the P30, washed by water in wet weather, you must pass under the calcite flow to reach the head of the P48.

The route is fairly obvious; take the simplest way. What follows heads off to the left (NW). You must then progress by going back up while always staying in the large volumes. You then arrive in a room of 7m x 5m; what follows is on the left. At the base of the P14, you must climb into the meander to go and find the head of the 30-metre pit. The P30 is broken into 2 points. At its base, you must pass under the calcite flow to reach the head of the P48 (handline). The latter is rigged with only 2 points.
