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).
