Diving notes

From the beach or by boat, you go to one of the 9 dive entry points (please ask for it). Due to boat traffic, it is highly recommended to bring a dive flag with you.

Caution! The bathymatry indicates a strong slope gradient. It is mostly important to watch your buoyancy. The depth can reach 260’. Localisation of two sites needs to be confirmed due to contradictory informations on older maps: the cavern et the cliffs.

Entry points


Note: directions are accurate as possible, it is mostly recommended to dive with someone you knows the site.
