Mafia Island – The Hidden Marine Paradise

Overview

Tucked away in the warm waters of the Indian Ocean, Mafia Island is one of Tanzania’s most spectacular and least-visited coastal gems. Part of the Mafia Archipelago and located southeast of Dar es Salaam, this island is a sanctuary for marine life, tranquil beach escapes, and untouched Swahili culture. Known for its exceptional diving, snorkeling, and seasonal whale shark encounters, Mafia offers a more off-the-beaten-path coastal experience compared to its sister island, Zanzibar.

A visit to Mafia is perfect for travelers seeking raw natural beauty, rich coral reefs, and meaningful interaction with local fishing communities.


Top Highlights

Mafia Island Marine Park

Covering over 820 square kilometers, this marine park is a haven for divers and snorkelers. Its coral gardens are home to over 400 species of fish, vibrant reef life, and five types of sea turtles. Protected since 1995, it’s one of the best-preserved marine environments in East Africa.
