Sec d’Ulysse is a boat dive over trenches and Posidonia meadows.
Sec d’Ulysse is a Bonifacio boat dive over broken rock, trenches, and broad Posidonia meadows. The route is more of a slow search along relief than a single wall, so buoyancy and patient scanning matter more than speed. Plan it as a settled-weather outing with a local operator and an experienced scuba team. Large groupers and dense fish life are the main draw, with the reserve adding barracuda and other Mediterranean species.

Community notes to help plan your visit.
Scuba Diving
Boat dive over trenches and Posidonia meadows. A slow search pattern along the relief is the best way to work the site.
Freediving
Not a practical freedive target; the boat-access, deeper profile makes scuba the sensible choice.
Snorkeling
Not a practical snorkel site; the useful structure sits below surface-skimming range and suits scuba better.
