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 del Grongo offers some of Portofino & Liguria's richest cave diving. Water ranges 14-27°C, warmest July, August, September.
Grotta del Grongo is a straightforward cave dive, accessible to most divers comfortable in overhead environments. We’ve found decent visibility here on good days, often around 15 metres, which helps when navigating the darker sections. Look out for the resident conger eels tucked into crevices, giving the cave its name. It’s a good choice for a second dive or those looking to explore a Mediterranean grotto without extreme technical demands.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
