Mahavelona Plateau is a boat-access plateau dive off Nosy Be with coral cover, schools of fish, and regular action from stingrays and small critters. The site is easy to read once underwater, but current is part of the profile, so it suits divers who are comfortable keeping a steady trim and tracking the boat. Expect a guided dayboat rhythm and usually very good water clarity.
