Madrépore Manta Point is a boat-access Nosy Be reef dive with a two-step profile, a garden-eel corridor, and a bright coral top. Tide timing matters, but the reward is a lively mix of manta-ray chances, stingrays, frogfish, crocodile fish, scorpionfish, lionfish, and reef fish moving over the sand and coral. It feels like a classic offshore reef outing rather than a simple shore site.
