Why dive here
With 74+ marine species recorded in the area - including blue sharks, dolphins, mobula rays (devil rays), oceanic whitetip sharks and ocean sunfish (mola mola) - Le Grottace offers some of Sardinia's richest cave diving. Water ranges 14-27°C, warmest July, August, September.
Le Grottace offers a solid cave diving experience in Sardinia. It’s a series of interconnected caverns and swim-throughs, with light filtering in from various openings creating some interesting visual effects. We’d suggest this site for divers comfortable in overhead environments, particularly those keen on exploring the unique geology of the Mediterranean. Expect to navigate through narrow passages and encounter typical cave inhabitants like shrimps and small crabs.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
