The dive

A shaft entrance (aven) near the hamlet of Lacroix: a 40 m rope descent leads to two sets of sumps, a short, shallow one to the south and one to the north reaching -42 m at 480 m.

Check the rope anchor carefully: it is often damaged.
Profile and sections

A shaft entrance (aven) near the hamlet of Lacroix: a 40 m rope descent leads to two sets of sumps, a short, shallow one to the south and one to the north reaching -42 m at 480 m. Watch out for snakes and frogs in the shaft while abseiling.

Depth and profile
40 m shaft, over 3 m wide. At the bottom you can go two ways. South: two successive sumps (30 m / -3 and 15 m / -6) to a restriction. North: an elliptical passage, a 100 m sump to a junction at -14 m. Straight on at the same depth a roomy 2 × 2 m tube that ends abruptly at a restriction 290 m from the entrance. The other branch drops into a 2 × 1 m passage to -38 m (400 m from the start of the sump), rises to -30 m and then descends in steps to a restriction at -42 m, 480 m from the entrance.
Configuration
All gear has to go down a 40 m shaft and back up, and the north branch narrows to 2 × 1 m: sidemount (estimate). No backmount.
DPV: Not DPV-suitable (estimate)
All gear goes down a 40 m shaft, and the passages are 2 × 2 and 2 × 1 m with restrictions: no scooter.

How to get there

From Saint-André-de-Cruzières take the D225 towards Beaulieu and turn right to Lacroix (La Croix) on the way. Go through the hamlet, past the sign 'La Manaudière' (holiday home). After the last house the road, unpaved by now, crosses a small dry stream bed (44°19.310'N 4°13.803'E). At the next junction turn right and immediately left, after 150 m right again and then follow the path to the left. 50 m on, a hollow on the right holds the shaft entrance, almost completely hidden by a fig tree growing out of it.

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).
