About this spot
Grotta di San Francesco is a cave dive site nestled within the Sanctuaire Pelagos marine protected area in Italy. The grotto offers a unique underwater exploration experience in one of the Mediterranean's most carefully managed waters. The site draws divers seeking the technical and aesthetic challenges of cave diving in a protected environment. The dive takes place within a designated marine sanctuary, meaning access follows strict conservation rules. This protection ensures the site remains pristine and biodiverse. Twelve species have been documented at the location, giving divers a solid sense of what marine life to expect. The grotto itself provides dramatic rock formations and the geological interest that makes cave diving compelling. Year-round conditions mean planning can be flexible. Three community videos are available online, offering real footage of the site and conditions. These videos help new divers understand the layout and prepare for the experience. The protected status means you'll share the water with a site that's actively managed for ecological health. Before diving, check current access requirements and any permit needs specific to the Sanctuaire Pelagos. Equipment and skills for cave diving are essential—this is not an entry-level dive. Local dive operators familiar with the site and sanctuary regulations should guide your visit.
