About Mafia Island

Reefs, whale sharks and island calm

Off the Rufiji Delta, south of Dar es Salaam

Mafia Island lies south of Zanzibar at the mouth of the Rufiji, its marine park protecting reefs, seagrass and a seasonal population of whale sharks.

Life here is slow and low-key — snorkelling, diving, sandbank picnics and, in season, swimming alongside the world’s largest fish.
