Дайв-сайты: Eastern Madagascar

Humpback whales migrate to the warm waters around Ile Sainte-Marie to breed and calve from July through September, with peak activity in August and early September. The channel between the island and mainland Madagascar serves as a nursery, and mothers with calves are regularly observed from shore and boat. While underwater encounters with whales are not guaranteed, divers frequently hear whale song during reef dives, and snorkel encounters with whales are offered by local operators under strict approach guidelines.

Ile Sainte-Marie (also called Nosy Boraha) is reached by domestic flight from Antananarivo, the capital of Madagascar, which takes approximately one hour. Flights operate several times per week during peak season. Alternatively, you can travel overland to the eastern port town of Soanierana-Ivongo and take a ferry, though this route is long and the ferry crossing can be rough. Several small hotels and eco-lodges on the island cater to divers and whale-watching visitors. Advance booking is essential during whale season.

Ile Sainte-Marie offers excellent reef diving year-round, independent of whale season. The island's fringing reefs support healthy hard and soft coral growth with diverse fish communities including endemic Malagasy species. The western side of the island is more sheltered and offers better conditions for reef diving, with sandy slopes, coral gardens, and rocky pinnacles between 10 and 30 meters. October and November after the whales depart offer warm water, good visibility, and uncrowded dive sites.
