Scuba diving in Cassis Bay allows you to discover a large number of Mediterranean species.
The practice of diving, for beginners or experienced divers, can be done using existing clubs like Narval Plongée. The seabed around in the heart of the Calanques National Park attracts a large number of divers every year. Sites such as La Cassidaigne, La Pointe Cacau, Figuière or Castel Vieil are famous for their drop offs, the fixed flora and fauna or the atmosphere and the pleasure of the dives.
The grouper, an emblematic species of the Mediterranean, has been protected since 1993. The combined effects of successive moratoria, the gradual arrival of young individuals from the south of the Mediterranean in the early 1990s and the gradual warming of the waters have contributed to the successful renewal of grouper populations.
Much rarer and for the very lucky, dolphins can be spotted in the bay.
You can also discover the sea slugs that can be observed there.
