Why is Mafia Island worth a trip?
With Tanzania's first marine national park and a reliable whale shark population, Mafia Island offers one of the calmest and most unspoiled diving destinations in East Africa, entirely without Zanzibar's tourist infrastructure. Anyone looking for remote ruins, pristine coral reefs and beaches with hardly any other travelers will find it here.
Unlike Zanzibar or Pemba, which belong to the semi-autonomous Zanzibar archipelago, Mafia Island is part of Tanzania's mainland Pwani region. That explains why the island has so far been far less developed for tourism: hardly any large resorts, no mass transport, but simple lodges around Chole Bay.
For most travelers, Mafia Island is an add-on stop to a Tanzania or Zanzibar trip, not the sole destination; those who accept the small-plane journey get reefs and ruins with practically no other visitors in return. Details on flight schedules, ferries and entry rules are subject to change and reflect the status as of September 2026.

What does Mafia Island feel like?
Mafia Island feels unspoiled and lightly developed: over 65,000 people live here, most of them earning a living from fishing and small-scale farming, not tourism. The main town of Kilindoni on the west coast is more a market and administrative town than a holiday centre.
Roads are mostly unpaved, and power and water supply outside Kilindoni and a few lodges are basic; visitors come to Mafia Island primarily for the marine national park and the quiet, not for comfort or nightlife.
The tourist infrastructure is concentrated in a handful of lodges around Chole Bay in the southeast of the island, right on the edge of the marine national park; most diving and snorkeling trips and boat excursions to the offshore islands start from there.

Which places are worth visiting on Mafia Island?
The Mafia Island Marine Park with its coral reefs and whale shark aggregation is the tourist centre, and Chole Bay in the southeast is the practical starting point for boats and lodges. Historically significant are Chole Island with an old trading settlement and the Kua ruins on the neighbouring island of Juani.
Mafia Island Marine Park
Founded in 1995, the Mafia Island Marine Park is Tanzania's first marine national park with several use zones, protecting a roughly 822 km² marine area around the island. It is managed by Tanzania's Marine Parks and Reserves Authority.
A 2003 survey found only about 14% live coral cover within the park, but the destructive coral mining that used to be widespread has declined significantly since the park's founding. For food fish such as the blackspot snapper, biomass measured within the protected zones was six to ten times greater than outside them — a "spillover effect" that also benefits fishing around the island.
Whale sharks off Mafia Island
The park is known for a resident whale shark population that is regularly visited for snorkeling off the island's coast; Mafia Island is one of the places worldwide where whale sharks gather seasonally to feed. Unlike in many other places, the animals can often be observed here right from the beach near the reef, with no boat required.
Kilindoni
Kilindoni on the west coast is the island's administrative seat and main market town, with the airport close by. Most lodges organize transfers from here to the opposite east side of the island.
Chole Bay, Chole Island and Juani
Chole Bay in the southeast is protected by offshore reefs and is the starting point for most boat, diving and snorkeling trips. In the bay lies Chole Island, historically an important trading settlement whose ruins still recall its former prosperity.
On neighbouring Juani Island lie the Kua ruins, the remains of a medieval Swahili trading town. It was destroyed by attackers from Madagascar in the mid-1820s and has not been resettled since; mosque ruins and burial sites still stand today in the dense coastal forest.
When is the best time to visit Mafia Island?
Mafia Island is tropically warm with highs mostly between 27 and 30 °C; the driest months are June to September with barely more than 20 mm of rain a month, while March to May, with over 260 mm in places, is by far the wettest time. For diving and snorkeling, the dry season from June to September is considered the most reliable for visibility.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| High °C | 29.8 | 29.9 | 29.6 | 28.8 | 28 | 27.5 | 27.1 | 27.5 | 28.3 | 29.2 | 29.9 | 30.1 |
| Low °C | 26.7 | 26.7 | 26.9 | 26.5 | 25.2 | 23.9 | 23.4 | 23.6 | 24.2 | 25.2 | 26.2 | 26.8 |
| Precipitation mm | 123 | 116 | 184 | 263 | 117 | 20 | 11 | 12 | 16 | 54 | 79 | 120 |
From March to May, the "long rains" bring heavy, often multi-day downpours and reduced underwater visibility; many lodges on Mafia Island scale back operations or close entirely during this period. The short rains in November are considerably weaker.
Anyone traveling specifically for the whale sharks should ask the respective lodge or dive centre about sighting chances on the ground, since the animals move seasonally between different spots within the park and no fixed calendar week guarantees sightings.
Because Mafia Island can only be reached by small plane or boat connection, heavy showers during the long rains occasionally affect flight schedules; a time buffer for connecting flights from Dar es Salaam is advisable during this period.

What do you need to enter Mafia Island?
Swiss, German and Austrian nationals need a visa for Tanzania, obtained either in advance online as an e-visa or on arrival as a Visa on Arrival paid in US dollar banknotes of $50 or $100 denominations. Because Mafia Island can only be reached via Dar es Salaam, all entry formalities take place there, not on the island itself.
Tanzania's e-visa system has been in operation since November 2018 and is preferred by many travelers over the queue at the airport; those instead getting a Visa on Arrival should bring suitable US dollar banknotes, since other means of payment are not always accepted at the counter.
The official authorities are always authoritative: the Federal Foreign Office, the BMEIA and the FDFA each maintain their own, regularly updated travel advisories for Tanzania; check the current entry rules there before departure.
The travel insurance from the Zanzibar Insurance Corporation, mandatory for entry to Zanzibar, applies to the Zanzibar islands of Unguja and Pemba; for Mafia Island, as part of the mainland Pwani region, this requirement does not apply according to available information.

What vaccinations and health risks apply on Mafia Island?
For all of Tanzania below 1,800 m elevation, and therefore also for Mafia Island at sea level, the CDC reports year-round malaria risk, predominantly from the dangerous Plasmodium falciparum parasite. Malaria prophylaxis should therefore be discussed with a doctor before the trip.
Besides up-to-date routine vaccinations, hepatitis A is recommended for practically all travelers and hepatitis B for most; typhoid is recommended for most travelers to Tanzania. The CDC also points to the cholera risk in Tanzania, so safe drinking water and well-cooked food are important.
On Mafia Island itself there is only basic medical care in Kilindoni; more serious cases are evacuated to Dar es Salaam. Travel insurance with repatriation cover is therefore important, especially for diving accidents, where a decompression chamber is not available on site.
Dengue also occurs in Tanzania, so consistent mosquito protection in addition to malaria prophylaxis makes sense. Yellow fever is not required for direct entry without a prior stay in a yellow-fever country.

How safe is Mafia Island for travelers?
The Federal Foreign Office, the BMEIA and the FDFA are not aware of any particular safety risks for Mafia Island itself; the island is considered calm and largely unproblematic for tourism. The general travel advisories for Tanzania still apply, particularly regarding petty crime in larger cities like Dar es Salaam on the way to the island.
Because medical and infrastructural provision on the island is basic, the greater practical risk lies in diving and boating accidents far from quick help, not in crime. Divers should look for a reputable, well-equipped dive centre with oxygen first-aid equipment.

How do you get to Mafia Island?
Mafia Island has no international airport; international visitors enter via Dar es Salaam and continue from there by small plane with Auric Air, Coastal Aviation or Tropical Air to Mafia Airport (MFA). Alternatively, a ferry runs from the mainland port of Nyamisati to the island.
| Connection | Operator | Duration | Note |
|---|---|---|---|
| Dar es Salaam – Mafia Island (MFA), flight | Auric Air / Tropical Air | small plane | several times a week |
| Dar es Salaam / Zanzibar / Pemba – Mafia Island, flight | Coastal Aviation | small plane | also connects Mafia with Tanga and the Selous area |
| Nyamisati (mainland) – Mafia Island, ferry | local ferry | around 4.5 h | daily departure in the afternoon, around 16,000 TZS |
Mafia Airport (MFA) sits right next to Kilindoni and has a roughly 1,630 m long paved runway; from here most lodges organize a boat transfer across the Mafia Channel to their accommodations at Chole Bay in the southeast of the island.
Because scheduled international flights to Tanzania only go via Dar es Salaam, Kilimanjaro or Zanzibar City, any onward journey to Mafia Island requires at least one stopover; a time buffer of two to three hours for the connecting flight is advisable, as the small planes have smaller delay margins than large scheduled flights.
On the island itself there are hardly any paved roads; most lodges organize transfers by boat or four-wheel-drive vehicle directly from the airport or the ferry jetty.
How do you pay on Mafia Island?
The national currency is the Tanzanian shilling (TZS), which has replaced the East African shilling zone in Tanzania since 1966 and applies to all of Tanzania including Zanzibar and Pemba. There are hardly any ATMs on Mafia Island itself, but larger lodges often also accept US dollars in cash or credit cards with a surcharge.
Because the island is remote and lacks banking infrastructure, it is advisable to exchange or withdraw enough cash already in Dar es Salaam; many lodge prices are quoted and billed directly in US dollars anyway, while local shillings are more practical for boat trips and market purchases.

Where do you stay on Mafia Island?
Accommodation options are concentrated in simple to upscale lodges around Chole Bay in the southeast, right on the edge of the marine national park. Large international hotel chains are entirely absent, and many properties are specialized diving and nature lodges with few rooms.
Those staying in Kilindoni itself are closer to the airport and the market but farther from the reefs and Chole Bay; most travelers therefore prefer a lodge directly on the east coast with a short boat ride to the diving and snorkeling areas.
What do you eat on Mafia Island?
Fish and seafood from the surrounding reefs form the basis of the cuisine, supplemented by rice, cassava and coconut milk in East African coastal tradition. Restaurants outside the lodges are limited to basic provisions in Kilindoni.
Because practically all visitors stay in lodges around Chole Bay, food is almost always included in the accommodation price; fresh fish from the lodge's own boat is standard there, and independent restaurants catering to tourists are rare on the island.
What culture shapes Mafia Island?
The island's culture is Swahili in character, as along the entire East African coast, with a long history as a trading post between the mainland, Zanzibar and the Indian Ocean. The ruins of Kua and Chole Island bear witness to a heyday well before today's tourist development.
The population lives predominantly from fishing and small-scale farming; mosque-centred village structures and a pronounced daily rhythm tied to the tides shape the island's pace far more than tourism does.
What can you experience on Mafia Island?
Highlights include snorkeling or diving trips to the whale sharks and coral reefs of the marine national park, a boat trip to the Kua ruins on Juani Island, and diving on the reefs of Chole Bay. Added to that are bird watching in the mangroves and outings with local fishermen.
Dive centres at Chole Bay offer both beginner courses and trips to deeper reefs on the outer edge of the marine national park; visibility is considered good thanks to low boat traffic, especially in the dry season from June to September.
Boat tours to Chole Island and the Kua ruins on Juani can usually be combined in one morning and are organized by the lodges at Chole Bay; established paths through the coastal forest to the ruins are simple but sometimes overgrown.
The Mafia Island Marine Park is also recognized as an Important Bird Area; mangroves and sandbanks around the island attract numerous wading birds and seabirds that can be observed well from smaller boats.
How do you travel responsibly on Mafia Island?
The Mafia Island Marine Park shows how fishing and tourism can be combined in protected zones: fish biomass within the zones is several times higher than outside them, which also benefits the surrounding fishing villages. Those who book excursions through certified dive centres support this protection model directly via the park fees.
Because live coral cover in the park was already estimated at only around 14% in 2003, care while snorkeling and diving — not touching coral, not feeding fish — is especially important for the reefs' slow recovery.

What can Mafia Island be combined with?
Because all flights go via Dar es Salaam, a combination with a Tanzania mainland trip or a Zanzibar stay is a natural fit. Direct small-plane connections also exist to Zanzibar City, Pemba and Tanga.
Those already planning a safari in the Selous area or a Zanzibar beach stay can add Mafia Island easily via one of Coastal Aviation's small-plane connections, without having to travel back via Dar es Salaam.

Who is Mafia Island suited for, and who less so?
Mafia Island suits divers, nature enthusiasts and anyone who can do without tourist infrastructure in favour of unspoiled surroundings. Those expecting Zanzibar's beach resorts, nightlife or a wide range of restaurants are in the wrong place on Mafia Island.
- Good fit: divers, nature observers, travelers seeking quiet and few other tourists, and culturally curious visitors with time for the Kua ruins.
- Less suited: those expecting a resort with full infrastructure, nightlife or a wide restaurant selection — Zanzibar City or the Tanzanian mainland are the better choice for that.
Does Mafia Island belong to Zanzibar or to Tanzania?
Mafia Island belongs administratively to the mainland Pwani region of the United Republic of Tanzania and is therefore legally clearly separate from the island region of Zanzibar with Unguja and Pemba; entry rules, national currency and time zone nonetheless follow the general Tanzanian standard and are summarized on the Tanzania country page.
The national currency is the Tanzanian shilling (TZS), and the time zone is UTC+3 (East Africa Time) year-round with no daylight saving — both apply nationwide, including on Mafia Island. The same visa rules apply for entry as for the entire country.
The decisive difference from Zanzibar and Pemba: because Mafia Island is not an island of the Zanzibar archipelago but belongs to the mainland Pwani region, the Zanzibar travel insurance mandatory for Zanzibar trips does not apply here according to available information. What this page describes independently are the marine national park, the whale shark population, the Kua ruins and travel by small plane or ferry — topics clearly distinct from Zanzibar and Pemba.
