Grotta di Nettuno
Protected Area
Area naturale marina protetta Capo Caccia Isola Piana
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) - Grotta di Nettuno offers some of Sardinia's richest cave diving. Water ranges 14-27°C, warmest July, August, September.
Diving Grotta di Nettuno is less about traditional reef exploration and more about the unique overhead environment. We navigate through large, dark caverns, using lights to pick out geological formations and the occasional small fish darting past. It's a dive for those comfortable in confined spaces, offering a different kind of underwater adventure than Sardinia's open reefs. Visibility can vary, so we always check conditions before heading out.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
