The dive

S2 descends at about 45° over gravel. At -25 m there is a squeeze, then a small passage to -33 and back up to -27.

S2 has tight squeezes at -25 m and at -51 m: deep and tight, for experienced sidemount divers only.
S2 goes to -43 m and on to the squeeze at -51 m: plan your gas and your turn point for that.
Profile and sections

S2 descends at about 45° over gravel. At -25 m there is a squeeze, then a small passage to -33 and back up to -27. Next come 20 m of narrow, chaotic passage, a 3 m drop and a slope to the squeeze at -51 m, beyond which it continues.

The cave is probably fed only by the area around Aubenas aerodrome. Explored in 1936 (Rabany); S1 was first passed in 1963 and -51 m was reached in 1995 (G. Lorente).

Depth and profile
S1 25 m / -3 (dries out at very low water) · small shaft + 200 m low wet passage (1 x 1.5 m) · S2 120 m / -43, then on to a squeeze at -51 m (1995) · development 575 m, range +12/-51
Configuration
Small sidemount only: low passage between S1 and S2 and squeezes in S2 at -25 and -51 m. Backmount not suitable (estimate).
DPV: Not DPV-suitable (estimate)
Short S1, low passage and tight S2: no scooter.

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).
