Snorkeling in Madagascar
Including Ankify Mangrove Channels, Ifaty Lagoon, and Nosy Iranja. On the map.
The vibe
Snorkeling here immerses you in a kaleidoscope of coral and critters that you won’t find on most tropical coasts. Visibility peaks during the cooler dry season, when the water clears from May to October. Most people join guided trips that include a marine‑park ticket, so the experience feels semi‑organized but still intimate.
