Mafia Island

Mafia Island is Tanzania's most unspoiled coastal destination — a quiet, unhurried island in the Indian Ocean south of Zanzibar, largely untouched by mass tourism. It sits at the heart of one of East Africa's most important marine parks, the Mafia Island Marine Park, and is globally renowned as a world-class dive and snorkel destination. Between October and March, whale sharks gather in the warm waters around the island, offering one of the most reliable and accessible whale shark encounters on the planet. The island's slow pace, mangrove creeks, and pristine reefs make it a genuine escape.
