About this spot
Tunnel de Planne sits within the Réserve naturelle de l'archipel de Riou, a marine protected area near Île Calseraigne in Marseille. The site draws divers to explore its namesake tunnel formation and the diverse marine habitat it creates. Year-round access means you can plan a trip whenever your schedule allows. Being inside a strict marine reserve means the site sees less pressure than many Mediterranean dives. The protected status supports healthy fish populations and stable ecosystems. The location benefits from Marseille's position on the French Riviera, with decent infrastructure for dive logistics. Species observations have been documented at 12 distinct points around the site, and community videos show what to expect underwater. This gives you a real preview before you go. The Riou archipelago is known for rocky terrain, kelp forests, and small reef structures typical of Provence diving. Divers should respect reserve rules: stay on marked routes, avoid touching bottom, and keep distance from wildlife. Local dive shops familiar with the reserve can brief you on current conditions and access procedures.
