Mafia Island

Mafia Island, Tanzania

Weathered coral-stone walls of the old Chole Mjini settlement stand against a sunset sky across Chole Bay.

Mafia Island offers reef diving, quiet beaches and old Swahili trading ruins, with far fewer visitors than Zanzibar, its better-known neighbour to the north.

The place

Mafia Island sits off the coast of Tanzania, facing the delta of the Rufiji River across a stretch of water called the Mafia Channel. In Swahili it is Kisiwa cha Mafia, and it is also known as Chole Shamba, a name that points to the farmland behind the old settlement on nearby Chole Island. It belongs to the mainland's Pwani Region and is not part of the Zanzibar archipelago, so the feel is closer to a Tanzanian coastal district than to a resort island. The facts record gives 40,801 residents, spread across fishing villages, coconut groves and small farms.

Kilindoni, on the western side, is the working town: the airstrip, the market, the harbour traffic and the shops all gather here. The eastern side is different. Chole Bay is a sheltered, deep anchorage, historically the island's real harbour, and today it is where most dive operators and lodges are based. Between the two coasts the land is low, green and sparsely settled, with sandy tracks rather than proper roads in many places.

The economy rests on fishing, small-scale farming and trade through Kilindoni. Tourism is real but modest. Divers, birdwatchers, sport anglers and people who simply want a slow week by the sea make up most of the visitors. Expect heat, humidity, patchy mobile signal and a pace that does not hurry for anyone. That is the appeal, and also the reason to arrive with realistic expectations about comforts and choice.

Its story

Mafia Island has been known to travellers since at least the eighth century, when it appears in records of Indian Ocean trade. Dhows linking East Africa with Arabia and farther east used it as a stopping place, and the small island of Chole Mjini in Chole Bay grew into a trading town with links to the southern coast and the gold and silver routes of the interior.

The past was not always peaceful. Kua, on Juani Island, was sacked by raiders who crossed from Madagascar by sea in a large fleet of canoes, and many of its people were killed or enslaved. The ruins at Kua were documented in three dimensions by the Zamani Project in 2018, which makes them easier to study than to visit.

In 1890 a treaty passed the island into German hands, and the colonial buildings that still stand on Chole date from that period. Germany paid the Sultan of Zanzibar for the island and a strip of mainland coast. In January 1915, British forces seized Mafia and used it as a base for the operation against the German cruiser Königsberg, which was hiding in the Rufiji Delta.

The name itself is debated. One view traces it to an Arabic word meaning a group or archipelago; another reads it as Swahili for a healthy place to live.

In 1995, with help from the World Wide Fund for Nature, a marine park was set up around the island's reefs. It was the first of its kind in Tanzania and still shapes how fishing and diving are managed here.

What to see

Culture

Mafia Island belongs to the Swahili coast, a culture shaped over centuries by African, Arab, Indian and later European contact. Most people on the island are Muslim, and the rhythm of the day follows the call to prayer, Friday gatherings and the fishing tides. Kiswahili is the everyday language, and a few greetings go a long way: people greet each other properly before any business, and rushing past the formalities is read as rude.

Fishing defines much of island life. Boats leave before dawn, catches are sorted on the beach, and the women of many villages handle drying, selling or farming. Boat building and sailmaking continue in the old way in some villages. Music on the island includes taarab, a sung poetry style with Arab and Indian roots that suits the Swahili coast, and bars and gatherings in Kilindoni often feature it.

The island's past as a trading stop is still visible in its architecture: coral-stone ruins, carved doors and the plain mosques of the older settlements. Life here is quiet, family-centred and unhurried, and visitors who stay a while tend to find that conversation matters more than sightseeing.

Outside the dive lodges, tourism is new enough that people notice how visitors behave. Ask before photographing anyone, and in villages and around mosques wear clothes that cover your shoulders and knees.

What to wear

Mafia Island dresses in the style of the wider Swahili coast. The kanga is the garment most people know: a printed cotton cloth, usually sold in pairs, with a Swahili proverb or message along the border. Women wrap it as a skirt, a head cover or a shawl, and it is also used to carry children and goods. Men wear the kikoi, a woven cotton wrap, at home or on the beach. For Friday prayers and festivals many men wear a kanzu, a long white robe, often with an embroidered kofia cap. Some women also wear the buibui, a dark overgarment, when out in public.

Day to day, what people actually wear is simpler: T-shirts, trousers or shorts for men, and long skirts, dresses or kanga with a top for women. Fishermen wear whatever dries quickly and tolerates salt. In Kilindoni the clothing is a little smarter, and market traders often wear bright prints.

For visitors, the climate calls for light, loose cotton or linen in pale colours, plus a wide-brimmed hat and strong sun protection. In villages and anywhere near a mosque, cover shoulders and knees, and keep swimwear for the beach and boats. Women may feel more comfortable with a kanga or light scarf to hand. Bring reef shoes or sturdy sandals for rocky shallows and coral rubble, and a thin long-sleeved shirt for boat trips, where the sun reflects off the water.

What to eat

Plan it

Best time. June to October is the usual choice: the weather is drier and the sea is calmer for boat trips and diving. The long rains arrive in the cooler months of April and May, and some lodges close then. Humidity and heat are constant, so schedule activity for early morning.

How long. 4–6

Getting there. Fly to Dar es Salaam, then take a small plane to Kilindoni airstrip on Mafia Island, a short flight. Two airlines serve the route; check schedules and baggage limits directly, as small aircraft are strict. From Kilindoni, lodges usually arrange road or boat transfers to the east coast and Chole Bay.
