Diving in Madagascar
Including Anakao, Ifaty, and Nosy Be. On the map.
The vibe
Scuba in Madagascar feels like descending into an underwater museum of giant sponges, manta rays, and reefs that have evolved in isolation. The dry season, roughly May to October, offers the calmest seas and the clearest water for deep dives. Dive shops run the day, so you’ll usually be part of a small group with a park ticket in hand, giving a semi‑structured adventure.

Anakao sits south of Toliara across the bay, featuring dramatic drop-offs and barrier reef channels facing the Mozambique Channel. The deep walls and open-ocean currents attract pelagic species, rays, and extensive hard coral gardens.

The shallow outer slopes and channels offer vibrant coral formations, moray eels, and diverse macro life. It is a relaxed destination for divers looking to explore untouched southern reefs.
Access. Dive operators based in Ifaty and nearby Toliara run boat trips out to the barrier reef gaps and drop-offs.
Notes. Calm conditions are most common from April to November. Depths typically range from 8 to 25 meters.

Dive sites like Tanikely National Park feature pristine coral gardens teeming with marine life. Visibility is generally excellent, making it ideal for both novice and experienced divers.
Access. Numerous dive centers operate directly out of Nosy Be and surrounding islets like Nosy Komba, offering daily boat trips and PADI certification courses.
