Nosy Be boat dive on a gorgonian plateau with macro life.
Normal access is via local Nosy Be dive boats.
Banco Rosario is a rocky offshore plateau on the Nosy Be dive circuit, usually run as a relaxed boat dive rather than a demanding profile. The site is known for broad gorgonian growth, mixed hard corals, a large cave, and plenty of macro subjects. Big turtles, barracuda, and seasonal whale-shark interest keep it on the standard Nosy Be itinerary.
