Best for intermediate divers, 30-39m, shore entry.
Lac de Laffrey is a freshwater Alpine lake offering shore diving at depths between 30 and 39 metres. This site is suited for intermediate divers comfortable with deep-water environments and limited visibility, which typically averages 5 metres. The lake features a reef structure and lacks significant currents, making descents manageable. The primary hazard is the consistently cold water, which requires appropriate thermal protection such as a drysuit or thick wetsuit throughout the year. The lake freezes during January and February. On-site facilities include parking and toilets, with boat charter services available for those wishing to reach deeper sections of the lake away from the shore entry point.
