The dive

A spring at Cénevières. After a small entrance comes a wide, elliptical passage (~2 × 5 m) with plenty of sand, scalloped rock and air bells.

Profile and sections

A spring at Cénevières. After a small entrance comes a wide, elliptical passage (~2 × 5 m) with plenty of sand, scalloped rock and air bells. The first part is often shallower (6–15 m).

The spring is fed by a sink about 10 km away. The system is about 2.9 km long, 1.9 km of it underwater in several sumps, down to -30 m.

Practical: the logistics are heavy, with scrambling with caving bags at high water. At low water the cave is often undiveable.

Depth and profile
Plan for -30 m: one source gives sumps down to that depth. Per the FFESSM topo, eight sumps: S1 95 m, S2 265 m and S3 10 m (all -5 m), S4 350 m (-10 m), S5 8 m (-2 m), S6 200 m (-14 m), S7 17 m (-4 m), S8 462 m (-23 m); explored to 1,767 m in 1977.
Configuration
Backmount fine; sidemount handy for carrying
DPV: DPV possible
Shallow; a small scooter has been used, but low/narrow stretches, air bells and carries limit the gain
Who can dive where
  • CaveAt least Full cave
  • Whole caveConfigurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
  • Whole caveGoes down to 30 m (trimix or deco may be needed) · doesn't decide who may dive
Dry sections / haulingDepends on water level or swell

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.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Based on personal notes; page numbers refer to Stefan Schiemann's Cave Diving Guide. Certification requirements are estimates — no substitute for local knowledge. Drive times: from Marcilhac taken from the guide, elsewhere calculated by road (OSRM, OpenStreetMap). The Doux de Coly and six springs that are closed to divers come from public sources (plongeesout/FFS, the CDS46 list of springs with access rules, Sept 2026). The pins of 14 of the 16 sites listed by The Cave To Be (Gramat) on its website come from there (Oct 2026); the Pou-Meyssen pin comes from The Hidden River Project, and the Marchepied pin was checked and kept. Access, sumps, history and hazards of many sites were added in November 2026 from public sources: the FFS site sheets (plongeesout), Spelunca, FFESSM magazines, the CDS46 and Grotto Map; the pins of Meyraguet, Goul Naou and the Oeil de la Doue come from the FFS. In November 2026 the CDS du Lot named by e-mail the 16 springs that divers may visit; the other springs in the Lot are marked closed.
