Vallée aux Mérous

★★★★☆ (144)

A direct descent into the blue towards a grey sandy bottom. You’ll see a beautiful 48m-deep rift, large gorgonians sheltering a colony of groupers, and schools of pufferfish. A deep dive that can be made difficult by the current.

The main attraction of this dive is the presence of numerous groupers, schools of hogfish and not forgetting the red-foot anemones and their clownfish.
