Mafia Island is an archipelago in the Indian Ocean, situated about 25 kilometers off the coast of Tanzania, south of Zanzibar. The island is famous for its exceptional marine park, established in 1995, which protects one of East Africa's most intact coral reef systems. Historically, Mafia was a significant hub on the ancient trade routes between Africa, Persia, and India, as evidenced by 8th-century ruins in Chole Bay. Today, the island is a world-class destination for swimming with whale sharks, which gather here in large numbers between October and March. The local economy traditionally relies on fishing and the cultivation of coconut palms and cashew nuts. In contrast to the busy Zanzibar, Mafia features a tranquil atmosphere and pristine natural beaches that appeal to eco-conscious travelers.

Parking
Since this is an island off the Tanzanian coast, vehicle transport is limited. Most visitors leave their cars in secure long-term parking in Dar es Salaam before taking a flight or boat.
Safety
Always respect local marine currents when swimming and follow local advice regarding tides. Sun exposure can be intense, so continuous hydration and shaded breaks are usually necessary.
