Tanikely protected reefs, Sakatia turtles and land-based Nosy Be diving
Overview
Plan Nosy Be as a land-based Indian Ocean dive holiday, not an offshore liveaboard expedition. Morning boats from Ambatoloaka and Madirokely serve reef dives near Nosy Tanikely Marine National Park, Nosy Sakatia, local walls and wrecks. Tanikely is the most accessible protected-reef and introductory-diving focus; Sakatia adds coral sites and turtle-focused snorkeling. Dedicated freediving instruction is advertised at Madirokely. The nearby Lokobe forest, Mount Passot and Nosy Komba make strong alternatives for non-divers. May to October is the most dependable general planning window, while whale sharks are seasonally observed around September to December, commonly October and November. Park tickets, operator availability, sea conditions, insurance and an independently verified evacuation plan matter more than any promised encounter.
Morning two-dive boats depart from Nosy Be visitor bases; the main experience does not require sleeping at sea. Operator format.
Nosy Tanihely Marine National Park supports guided introductory diving, snorkeling and marine wildlife observation with formal visitor rules and a ticket. .
