The dive

The entrance zone is impressive, with dripstone and partly snow-white calcite.

The entrance is a sink: in a storm you can get trapped inside. Check the weather carefully beforehand and only go when it is dry, with no rain or storms in the area in the week before.
Profile and sections

The entrance zone is impressive, with dripstone and partly snow-white calcite.

This is a sink (goule) of the Claysse near the hamlet of Sauvas (Saint-Paul-le-Jeune): water flows into the cave here instead of out of it, as at the Foussoubie. According to the guide it resurfaces in the Grotte de la Cotepatière; the Claysse as a whole resurfaces ~6 km further on at the Moulin de Pichegru (Peyraou du Moulin). The cave is part of the Sauvas–Cocalière system (14.5 km), between the Chadouillet and Baume de Chazelle systems, with which it is probably connected. Per Clerc (2009) two passages formed along two perpendicular fractures meet here; in 1999 a junction with the Évent de Peyrejal was still 50–200 m short.

Depth and profile
Depth unknown. Dry at first: the entrance zone has pools that you pass on a ledge along the wall, and after ~100 m a rope helps you on. Further into the kilometre-long system several sumps have been explored, with passages beyond.
Configuration
The gear has to go through a dry cave with pools and a rope section to the sumps: light kit, sidemount or small cylinders (estimate). No backmount.
DPV: Not DPV-suitable (estimate)
A dry cave with pools and a rope section before the sumps: no scooter.

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.

How to get there

From Sauvas take the D901 towards Chadouillet. After a sharp right-left-right series of bends the road crosses a bridge: park right after it and take the path down to the bed of the Claysse. Follow it to the left to the impressive, chasm-like entrance, 30–40 m on.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Sept 2026) and the guide (2024 edition): CDS 07 and CDS 30, plongeesout.ffspeleo.fr, Spelunca, Grottocenter, foussoubie.fr, club reports and news. Page numbers refer to Stefan Schiemann's Cave Diving Guide Ardèche, Gard & Vaucluse. Map pins come from the GPS coordinates in the guide, from Grottocenter/OpenStreetMap or were converted from Lambert grid references (may be 50–100 m off). For some caves the data is thin or old: check it in the guide and locally. Certification requirements are estimates. Drive times are calculated by road for each stay (OSRM, OpenStreetMap).
