Top 5 Dive Sites In Madagascar

Madagascar is a land of unbelievable mystery, excitement, and adventure, both on land and under the water. Madagascar is located just off the east coast of Africa, in the Indian Ocean. If you’re a nature lover, then Madagascar should certainly be on your bucket list.

Nosy Be, also known as ‘The Perfume Island’ is located off the northwest coast of Madagascar. Nosy Be is where most of the top diving sites can be found, however, there are quite a few smaller islands found nearby, which also have an amazing collection of dive sites for all levels of diver.

These small islands include Nosy Komba, Nosy Sakatia, Nosy Tanikely, Nosy Miitsio and Nosy Iranja, which are all home to incredibly diverse marine life including Manta Rays, Marine Turtles, and Stingrays. If you’re looking for some incredible diving experiences with Whale Sharks, then the time to visit Madagascar is between the months of November through December. However, if you’re planning a trip and want to get the best out of what Madagascar has to offer, under the surface, the best time to visit is between April and August. Around this time, the visibility is excellent, being over 30m. However, if you do find the visibility has dropped around this time, it is usually due to a huge Plankton bloom, which in itself attracts plenty of large predators.

The waters surrounding Madagascar are home to one of the world’s longest, continuous coral reefs. Not only is this country renowned for its incredible land animals, but also the many marine species endemic to the area. In Madagascar, you’ll find 5 out of the 7 species of marine turtle, over 56 types of sharks, over 34 types of whales and dolphins, 1300 types of bony fish and over 300 species of hard coral. These waters are just teaming with life and should not be missed.

Diving in Madagascar can also be experienced via a liveaboard, with the best locations being within the Mitsio (north of Nosy Be) and Radames (west of Nosy Be) archipelagos. In addition, the east coast of Madagascar, for example, Saint Marie, is known as one of the migratory routes for Humpback Whales throughout the months of July to September. They have also been known to give birth around this time, making it an awesome experience for divers.
