les Grottes - Corsica

Les Grottes, or The Caves, in Corsica, offers a gentle introduction to cave diving. At a maximum depth of 16 metres, it's accessible for beginner divers looking to explore overhead environments without complex navigation. We often spot schooling damselfish and occasional moray eels lurking in the crevices. The site is best enjoyed on a calm day when sunlight filters in, creating a beautiful light show.
