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) - Nereo Cave offers some of Sardinia's richest cave diving. Water ranges 14-27°C, warmest July, August, September.
Nereo Cave, the largest underwater cave in the Mediterranean, offers a complex dive for advanced divers. We’ve found depths ranging from 10m to 30m, featuring impressive red coral formations. Look for cowfish and slender seagrass in the clearer sections. It’s a site best suited for those comfortable with overhead environments and good buoyancy.
