La grotte sans fond
Protected Area
Iles Marseillaises - Cassidaigne
Why dive here
With 157+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and mobula rays (devil rays) - La grotte sans fond offers some of Marseille & Calanques's richest cave diving. Water ranges 14-25°C, warmest July, August, September.
La grotte sans fond offers a true cave diving experience in the Calanques. You’ll navigate through tight passages and larger chambers, often in low light conditions, so good buoyancy and a calm demeanor are essential. We recommend this one for experienced cave divers looking for a technical challenge rather than abundant marine life.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
