Grotta Giusti
Why dive here
With 70+ marine species recorded in the area - including blue sharks, dolphins, humpback whales, mobula rays (devil rays) and oceanic whitetip sharks - Grotta Giusti offers some of Portofino & Liguria's richest cave diving. Water ranges 14-27°C, warmest July, August, September.
Grotta Giusti is a geothermal cave system, more of a spa experience than a typical dive. You're swimming through warm, mineral-rich water in an underground grotto, with stalactites and stalagmites all around. Visibility is usually good inside the cave, though it's often a bit silty when other divers are present. It's a unique experience, perhaps best for those looking for something completely different from open water reef diving.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
