Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from public sources: the FFS site plongeesout (site sheets, reports, chamber list), Spelunca, Vercors Plongée, Visites Nature Vercors, Wikipedia, grottomap, DREAL Auvergne-Rhône-Alpes, CDS 38, Vercors Vertical, gouffre-berger.com, Vercors-Drôme tourism, plongeur.com, altituderando and decathlon-outdoor (September 2026). Much of the dive data comes from exploration reports (1997–2010) and sometimes differs between sources.
