The dive

This is a very aquatic 'caving' route: between the sumps there is an active stream, a large meander and a 4 m pitch. S2 can be bypassed via a higher level.

S1 is a bedding plane whose length changes with the water level; after rain it floods completely (EFPS, May 2008). Temporary resurgence: do not dive during or after rain.
Profile and sections

This is a very aquatic 'caving' route: between the sumps there is an active stream, a large meander and a 4 m pitch. S2 can be bypassed via a higher level. S3 is clayey with boulders, S5 comfortable with a sandy floor. Bones of large animals were found in S3.

The Event des Espeluches is a temporary resurgence (flows in wet periods) of the same system as Bourbouillet, Reméjadou and Ranc du Bœuf; upstream of S7 there are two connections with Ranc du Bœuf. Explored by J.-P. Baudu (2000–2001).

Depth and profile
S1 bedding plane (length varies with water level) · S2 20 m / -3 · S3 160 m / -2 · S4 25 m (low roof) · S5 230 m / -39 · S6 10–15 m · S7 terminal sump (boulder choke). Total >1,100 m, of which 510 m underwater; +10 / -40 m.
Configuration
Small sidemount or small cylinders: an EFPS course (2008) used twin 7 l or twin 10 l for the first sumps. S5 (230 m, -39 m) needs adequate gas. Backmount will not fit the bedding plane (estimate).
DPV: Not DPV-suitable (estimate)
Bedding planes, low roofs, short sumps and dry sections with a pitch: no scooter.

How to get there

From Saint-Alban-Auriolles take the D208 towards Chandolas, then right onto the D246 towards Lablachère. After 2 km, past a bridge, take the 800 m track towards the Domaine du Bourbouillet; at a small pond on the left, turn left down into a ravine and up the other side. Leave the cars at the top, walk down the path and follow the stream up to the entrance. Everything has to be carried down into the valley and back up.

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).
