Start
Petite-Terre

The S-shaped pass cuts through the eastern barrier reef. More than a dozen sites are marked along its walls: coral gardens, turtles, barracuda, reef sharks and, in season, manta rays.

Clubs operate from Mamoudzou and Petite-Terre; there are try-dives and outings for snorkellers.
