The dive

'Peyrol' (also 'pléoux') is the local name for a vauclusian spring. Recent data is lacking: the guide relies on a 1972 report by French divers and a 1994 profile.

Unstable restriction right after the entrance, with limited visibility. The data is old (1972/1994): only dive here with experience of unknown caves.
Down to -59 m: plan your gas and your turn depth for that.
Profile and sections

'Peyrol' (also 'pléoux') is the local name for a vauclusian spring. Recent data is lacking: the guide relies on a 1972 report by French divers and a 1994 profile. It matches the Peyrol (Pléoux) des Rouveyrols: a resurgence at 140 m altitude, about 50 m deep, with up to 6 m³/s at high water (Clerc 2009).

Depth and profile
Entrance shaft of ~20 m that is full to the rim in the wet season: the water level varies by ~22 m between winter and summer. Profile (D. Lorain 1994, in the guide): a basin 24 m across, an unstable restriction and a slope down to -59 m. 1972 description: a narrow, unstable passage down a shaft, a small chamber, a gallery of at most 2 × 3 m sloping at 20–25°, a larger chamber at -30 m (10 m up to a ceiling), and on the far side at ~-38 m a continuation possibly blocked by sand.
Configuration
Narrow, unstable passage right after the entrance: sidemount (estimate). In dry periods the gear has to go down the last ledge on a rope or ladder; down by the water there is enough room.
DPV: Not DPV-suitable (estimate)
An unstable restriction right after the entrance, then a passage of at most 2 × 3 m to a chamber at -30 m: too tight and too short for a scooter.

How to get there

From Saint-André-de-Cruzières take the D225 towards Beaulieu. In Pléoux take the first road on the left, to a small bridge; just before it turn left onto a track to an open area. From there (in summer along the dry stream bed) a path leads to the impressive entrance doline.

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).
