The mafia archipelago is part of Tanzania, strewn along the coast southeast of Dar es Salaam, it is governed by the mainland, not by the semi-autonomous region of Zanzibar. historically this island was on a cross path for traders along the eastern African coast, at present the island is popular for its protected reefs with large parts of the island's coast protected by the marine park. for this reason, it's arguably the best place in East Africa’s coast for scuba diving & snorkeling especially when you are keen to explore whale sharks.

Note: mafia island experience the longest whale shark season globally.
