Mafia Island Marine Park

It is the ocean here that is the great attraction. In 1995, the Mafia Island Marine Park was formed to protect the archipelago’s reefs. Almost half of Mafia’s coastline is part of Mafia Island Marine Park, a nature park, full of coral reef, mangrove forest and lagoons. This is the largest protected area in the Indian Ocean. The barrier reef, with 50 different corals and more than 460 species of fish, is a dream to divers and snorkelers. Mafia’s incredible and pure dive spots have remained a well-kept secret. Within Chole Bay, the shallow reefs are perfect for snorkelling or learning to dive. Outside the bay, its entrance is guarded by a long coral wall, attracting more experienced divers. Here are more than 50 kinds of coral, including giant table corals, huge stands of blue-tipped staghorn corals, and more than 400 species of fish. This is one of Tanzania’s best areas for diving. You’ll always see something exciting, from rainbow-colored clownfish to octopus, rays and the odd gigantic grouper or large potato cod. Sharks and dolphins are found in the deeper waters, and at night turtles haul themselves onto remote beaches to nest. Note that due to local winds and currents, dive sites outside the bay are often only safely accessible from about mid-September to the end of February. When you drive across Mafia to transfer to any of the lodges on the east coast, or to Chole Island, you will go through the Marine Park entrance gate on the main road, and you will have to pay daily fees in advance, depending on the size of your party and the length of your stay. Happily they take credit cards. Tanzania’s published marine park user fees put the non-East-African adult day rate at USD 20 before tax, and the gate charges the tax-inclusive figure in dollars or the shilling equivalent. Fees are set by Marine Parks and Reserves Tanzania and are revised from time to time, so confirm the current rate before you travel. On an Enclose Africa Safaris itinerary the park fees are quoted with your trip. (Checked 24 August 2026.) You will need to show your receipt and ticket every time you pass through the gate on this trans-island road.
