Everything you need to know about this dive site.
Dive Site Overview
Initially a prison fort constructed in 1586, Fort Brescou provides a historical focal point for its surrounding dive sites. These waters, situated on a volcanic base, present an accessible diving environment suitable for various skill levels, from beginners to experienced divers.
Exploring the area reveals a topography characterized by rocky depths of volcanic origin, complemented by vibrant coralligenous formations formed by calcareous algae. An artificial reef system, standing 6.5 m (21.3 ft) high, extends over 50 m (164 ft) with smaller modules, reaching maximum depths of around 20 m.
Divers can also explore areas like 'Les Tables', which are volcanic slabs featuring faults, with depths generally between 2 and 11 m. Shallower sections near the fort typically range within the introductory dive limits, providing straightforward conditions for initial skill development.
These geological features, combined with the artificial structures, create a diverse habitat. This makes the site a varied destination for underwater exploration, offering different experiences within a single area.
