About Impérial de Terre
Impérial de Terre is a boat-access rock dive off Riou in Marseille's Calanques. It is the shallowest of the Imperial trio, with a small arch, scree slopes, and an easy circuit around the rock that suits controlled, unhurried diving. Plan on a local boat, calm-weather conditions, and a site where the best moments come from coralligenous detail and patient buoyancy rather than depth.

Scuba Diving
Suitable for calm-water recreational diving and confidence-building boat dives; the arch and tunnels still call for careful buoyancy.
