Mafia Island
Mafia Island sits quietly south of Zanzibar, seeing only a fraction of the visitors that flock to its more famous neighbor, despite offering some of the best marine wildlife encounters anywhere on the Tanzanian coast. For travelers willing to trade a bit of convenience for genuine seclusion, Mafia is one of the most rewarding island extensions available.
What Makes Mafia Different from Zanzibar
Where Zanzibar has grown into a well-developed tourism destination with a wide range of resorts and activities, Mafia remains largely undeveloped, with a small number of lodges and a noticeably quieter pace of life. The trade-off is fewer dining and activity options compared to Zanzibar, in exchange for beaches and reefs that feel considerably less visited.
Whale Sharks: The Headline Draw
Mafia is one of the most reliable places in the world to swim alongside whale sharks, the largest fish species on Earth, drawn to the nutrient-rich waters of the channel during their feeding season. This single experience is enough to justify a Mafia stay on its own for many marine wildlife enthusiasts.
Beyond Whale Sharks: The Wider Marine Park
Mafia Island Marine Park protects a significant stretch of coral reef and surrounding waters, supporting healthy fish populations and good diving and snorkeling conditions across multiple sites. Humpback whales pass through seasonally as well, offering a second, separate wildlife encounter distinct from the whale sharks.
For a quieter beach experience, the Blue Lagoon and the Mange sandbank both offer calm, shallow water well suited to relaxed swimming and snorkeling away from any current.
History Worth Exploring
The archipelago carries real historical depth alongside its natural attractions. Chole Island holds the atmospheric ruins of a 19th-century trading settlement, now reclaimed by forest, while the ruins of Kua on nearby Juani Island tell the story of an entire abandoned Swahili trading town.
Fishing and Other Activities
Mafia is also a genuinely good destination for deep sea fishing, with strong game fish in the surrounding deep water, an activity that gets relatively little attention compared to the island’s marine wildlife but is well worth considering for anglers.
Best Time to Visit
Whale shark season generally runs from roughly October through March, making this the most popular window to visit, though conditions and timing can shift slightly year to year. Outside this window, Mafia remains a pleasant, quiet beach destination, simply without the whale shark encounters as the headline activity.
Getting There
Mafia is reached by a short domestic flight from Dar es Salaam or Zanzibar, making it a straightforward add-on despite its remote, undeveloped feel once you arrive.
How Mafia Fits Into Your Trip
Mafia works best as either a standalone beach and marine wildlife extension after a mainland safari, or as a quieter alternative to Zanzibar for travelers who have already experienced more developed island tourism elsewhere and want something different.

Mafia Island (394 km2) is located in the east coast of Tanzania opposite the delta of the Rufiji River. The 20 kilometres wide stretch of water between the delta and the island is called the Mafia Channel. Mafia Island is part of a small Tanzania’s Mafia archipelago in the Indian Ocean consists of one large island and several smaller islands, including Jibondo, Chole, Juani, Bwejuu, Mbarakuni, Shungumbili and Nyororo. Some of which are inhabited. The main town on Mafia is Kilindoni on the west coast. In the south beaches include secluded Ras Kisimani, just across from Bwejuu Island and Utende. On the east coast is Chole Bay, Mafia’s protected deep-water anchorage and original harbour. The bay is studded with islets, sandbanks and beaches, and is protected from the east by coral reefs and Juani Island.
The island lies across the trade routes from the Gulf and has seen Egyptian, Omani, Greco-Roman, Chines, Portuguese, English and German occupation, and has had a prominent place in the history of the East Coast of Africa, as it was a safe haven for ships to stop for water and for repairs. The Mafia Archipelago hosts antiquities dating back to the Eleventh Century, including ruins at Kisimani Mafia, Kanga, Kua on Juani Island and Chole Island.
The atmosphere of all the islands in Mafia is one of adventure: days are spent fishing or exploring exposed sand bars and untouched reefs, however the main appeal for many visitors is that it remains locked in a time warp of the early 20th Century.
Surrounded by a protected marine park, the diving, fishing and snorkeling here are the best in the entire region. Mafia is truly an excellent destination for those wanting to spend a bit of time in the underwater world and interested in nature and outdoor activities. Known for it’s location of the migratory Whale Sharks, spotting these magnificent creatures is an unforgettable experience of a lifetime.
The atmosphere of all the islands is one of adventure: days are spent fishing or exploring exposed sand bars and untouched reefs. Perhaps best for those mad keen on making diving the central focus of their Tanzania holiday.
Mafia is undoubtedly the best dive location in Tanzania. It’s a small haven that has a lot to offer and, quite exquisitely, is also suitable for less experienced divers. The reefs of the archipelago offer a staggeringly beautiful and varied display of marine life. The diversity of animal and plant life is hard to match, with over 50 types of corals and 400 species of fish so far identified. On top of that, Mafia offers one of the world’s best opportunities for snorkeling with whale sharks.
Mafia Island Marine Park
The marine park at Mafia Island extends over 822 km2, with more than 75% of it below the high-water mark. The area hosts an outstanding mosaic of tropic marine habitats including coral reefs, seagrass beds, mangroves, and inter- tidal flats. Two species of sea turtle use Mafia’s beaches as nesting grounds and the area has been recognized internationally as a critical site for biodiversity.
Several sites of historic ruins lie within the marine park area, some dating back to the C13th. Mafia Island’s separation from the mainland and its freedom from industrial development have ensured that its surrounding waters are some of the least contaminated in Tanzania. The marine park area has national importance as one of the few remaining reef complexes within Tanzania’s coastal waters in relatively untouched condition.
Marine Parks and Reserves are created as an important tool for conservation and tourism in Tanzania and worldwide. With the two, it is our responsibility to always balance them for the best of both present and future generations.
