Mafia IslandAbout Mafia Island
Mafia Island is part of an archipelago off Tanzania’s mainland and is known for its extensive coral reefs, mangroves and marine biodiversity. The island base supports diving and snorkelling operations, with a focus on reef conservation and small-scale accommodation.
The shallow channels and sheltered bays around the island create productive fishing and diving sites; Chole Bay and the surrounding reef systems are among the prime marine areas for visitors. Tourism on Mafia tends to be lower-intensity than on Zanzibar, appealing to divers, snorkelers and travellers seeking quieter beaches.
Conservation initiatives include a designated marine park that covers reefs and associated coastal habitats in order to protect fisheries and coral diversity. The island is part of Pwani Region and is connected to the Tanzanian mainland and nearby islands by small aircraft and ferries.
- Marine attractions: The island is noted for coral reefs, mangrove systems and relatively low-key marine tourism focused on snorkeling and diving rather than mass resorts.
What to See#
- Chole Bay: Chole Bay is a sheltered marine area with reefs and seagrass beds close to the main island where snorkeling, diving and small-boat trips are organised.
- Mafia Island Marine Park: The Mafia Island Marine Park protects offshore reefs, mangroves and seagrass areas and is the focus for managed diving and snorkeling activities.
