West-coast Reunion drift wall with rays, eels, and dolphins.
Tombant des Grottes is a west-coast Reunion wall dive with a steep drop-off and a rich plateau along the reef edge. The site is best approached as a relaxed drift, with alcyonarians on the rock and frequent sightings of moray eels, eagle rays, and occasional dolphins. It is a classic current-shaped dive that rewards steady buoyancy and attention to the wall.

Community notes to help plan your visit.
Scuba Diving
A wall dive spanning roughly 20–50 m with a life-rich plateau.
Freediving
Not a freedive-first site; the wall, depth, and drift conditions suit guided scuba much better than breath-hold exploration.
Snorkeling
Snorkeling is secondary here. Use only the calmer shallower edge if a local operator says conditions are suitable.
