Zanzibar is the cheapest and easiest of the three to reach, Mafia usually costs more because nearly everyone flies in on a small aircraft from Dar es Salaam or from a safari airstrip, and Pemba sits in the middle on ticket price but near the top on transfer and logistics costs. What really decides your bill is not the distance between the islands but aircraft size, season, baggage allowance, how many seats the airline can fill, and how far your hotel sits from the airstrip. The same short hop can cost noticeably more in late December than in May, and a cheap ticket to a remote beach can be wiped out by an expensive boat or vehicle transfer at the other end.
If you are planning a Tanzania beach finish for 2027 or 2028, the honest starting point is that these three islands are not variations of the same holiday. Zanzibar is a fully built tourism economy with an international airport, dozens of daily connections and a price range from backpacker to luxury. Mafia is a small, low-key island whose identity is built around a marine park and whale sharks. Pemba is greener, steeper, quieter and much less developed, with some of the best diving in East Africa and the fewest places to stay. Flight prices and travel costs follow directly from those differences, and so does the kind of traveller each island suits.
What each island actually is, before you compare a single ticket
Comparing fares without understanding the islands leads to the wrong decision. A traveller who wants a five-night beach break with restaurants, kite surfing and a short airport transfer should not be looking at Pemba. A diver chasing untouched walls and minimal boat traffic should not judge Mafia and Pemba by how many flights serve them.
Zanzibar: the island with the widest price ladder
Zanzibar has the only international airport of the three, so it can be reached directly from several regional and long-haul origins, and it is also the easiest island to add to a Kilimanjaro or safari itinerary. That volume of traffic is exactly why it can be cheap: competition, larger aircraft and year-round demand keep seats available across many price points. It is also why it can be expensive: in peak weeks, the cheap seats sell first and the remaining ones climb quickly.
The island is long, and where you stay changes your ground costs more than most people expect. Stone Town, Nungwi and Kendwa in the north, Paje and Jambiani on the east coast, and the quieter south-east beaches all have different transfer times from the airport and different price levels. A hotel that looks affordable can add a long private transfer each way, and on the east coast the tide matters for swimming hours in a way it does not in the north.
Mafia Island: small planes, a marine park and limited seats
Mafia is reached almost exclusively by light aircraft, typically from Dar es Salaam, and sometimes from safari airstrips if you are connecting from a game-viewing circuit. There is no large-aircraft service and no international arrival. That single fact explains most of the cost difference: fewer seats per departure, higher cost per seat to operate, and strict luggage limits that push photographers and divers into paying for extra baggage.
What you get for that money is a marine park with strong reef health, a genuinely small number of lodges, and a rhythm that stays quiet even in high season. Whale shark season draws a specific crowd, and dive boats fill around it. Outside those weeks, Mafia can feel almost private.
Pemba: the quietest island and the most expensive to move around
Pemba has an airport and receives regional flights, but frequencies are low and schedules shift between seasons. The island is hilly and the road network is slow, so a 40-kilometre transfer can take far longer than the map suggests. Dive sites and beaches are spread out, which means either choosing a lodge that sits close to what you came for, or accepting that boat and vehicle transfers will be a real line in your budget.
Accommodation is limited. That is part of the appeal, and also the reason last-minute Pemba planning is risky: when only a handful of properties operate in a given area, a fully booked week is fully booked, and there is no cheaper alternative down the road.
Flight prices: the five factors that move the number most
Across all three islands, ticket prices respond to the same handful of variables. Understanding them lets you judge whether a quote is reasonable or whether you are being asked to pay for convenience you do not need.
| Price driver | How it affects Zanzibar | How it affects Mafia | How it affects Pemba |
|---|---|---|---|
| Aircraft type and seat count | Larger aircraft, more seats, more competition | Light aircraft only, few seats per flight | Light aircraft, very low frequency |
| Season and demand | Strong peak pricing around Christmas, New Year and July–August | Peak tied to whale shark and dive season | Small peaks, but almost no spare capacity |
| Baggage allowance | Generous on international carriers, tight on regional hops | Strict soft-bag limits; excess is chargeable | Strict limits, and no easy alternative if you exceed them |
| Booking window | Wide range from early booking to last minute | Narrow; seats sell out well ahead in season | Narrowest of the three |
| Routing | Direct from several origins, or via Dar es Salaam | Almost always via Dar es Salaam | Usually via Dar es Salaam or Zanzibar |
Two practical consequences follow. First, on Zanzibar you can genuinely save money by being flexible about the day you fly and by accepting a connection instead of a direct service. Second, on Mafia and Pemba flexibility is limited, so the saving usually comes from choosing your dates around availability rather than hunting for a cheaper fare.
If your trip starts on the mainland, it helps to compare the mainland legs separately. Flights into the northern circuit and the coast are covered in our guides to Kilimanjaro Airport to Zanzibar flights and flights to Moshi and the nearest airports, while travellers arriving from Kenya often find better value routing through Nairobi — see Nairobi to Zanzibar flight prices.
Ground costs: where island budgets really separate
Ticket price is the visible number. The invisible one is what happens after landing, and this is where Mafia and Pemba often surprise people.
Transfers. On Zanzibar, shared shuttles and taxis run between the airport and the main beach areas throughout the day, so you can travel cheaply if you accept a shared vehicle and a longer ride. On Mafia and Pemba, transfers are usually private, arranged through the lodge, and priced accordingly. A remote lodge can add a substantial amount per person each way.
Accommodation range. Zanzibar offers everything from simple guesthouses to international resorts, which means you can trade location for price. Mafia has a small number of mid-range and upmarket properties with very little budget stock. Pemba has the thinnest choice of all, and prices reflect scarcity rather than luxury alone.
Marine park and conservation fees. All three islands charge conservation or marine park fees in some form, and rates differ between parks and change over time. Treat these as a fixed extra per person and confirm the current amount with your operator rather than relying on older blog posts.
Activities. Diving and snorkelling dominate costs on Mafia and Pemba, where a multi-day dive package is often the main expense after flights. On Zanzibar, activities are optional add-ons: a spice tour, a sandbank trip, a dhow sunset, kite surfing lessons. That difference matters if you are travelling with people who do not dive.
Food and drink. Zanzibar has the widest spread, from local street food to hotel restaurants. Mafia and Pemba lodges are often full board or half board by default, which raises the headline rate but removes the daily decision — and the daily spending.
Side-by-side comparison for trip planning
| Criteria | Zanzibar | Mafia Island | Pemba |
|---|---|---|---|
| Main access | International airport plus frequent regional flights | Light aircraft, usually from Dar es Salaam | Light aircraft, low frequency |
| Relative flight cost | Lowest, with the widest range | Higher per seat, limited capacity | Moderate to high, scarce seats |
| Relative ground cost | Widest range, cheapest if you plan transfers | Higher, private transfers and lodge pricing | Highest, long slow transfers |
| Accommodation choice | Very wide | Narrow, mostly mid to upmarket | Very narrow |
| Best for | Beach holidays, families, honeymoons, post-safari rest | Diving, whale sharks, small-scale quiet | Serious divers, off-grid quiet, repeat visitors |
| Minimum sensible stay | 4–5 nights | 4 nights | 5 nights |
| Main planning risk | Peak-season prices and beach choice | Seat availability and baggage limits | Availability, schedules and transfer time |
The pattern is consistent: Zanzibar wins on access and choice, Mafia wins on reef quality per traveller, Pemba wins on solitude and loses on convenience. None of them is objectively cheaper — they are cheaper for different kinds of trips.
Which island fits which traveller
Families and first-time visitors to Tanzania usually do best on Zanzibar. Flights are easier to fix, medical facilities and restaurants are more available, and if a child dislikes the sea or the tide, there are alternatives nearby. Couples finishing a Kiliman
Booking windows and the small-plane baggage trap
On Zanzibar, you can often decide a few weeks out because there are dozens of daily seats across several operators. Mafia and Pemba are different. A twelve-seat aircraft has no spare capacity in July, August or the December holidays. If you are set on specific dates, book three to four months ahead. If you are flexible, you can sometimes find seats closer to departure, but you may have to change your lodge dates to match the flight rather than the other way around.
What happens when a light-aircraft seat is not available
You may be offered a private charter, which costs significantly more per person. Or you may need to add a night in Dar es Salaam, which brings hotel and transfer costs. For Pemba, where frequencies are lowest, a missed connection can mean a two-day delay. Build a buffer day before any international departure, and treat the domestic flight as the fixed point around which the rest of the trip moves.
The baggage rule that catches divers
Light aircraft have strict weight limits, often around 15 kg per person in soft bags. Dive gear — BCD, regulator, wetsuit, fins, mask — can easily exceed that before you add clothes. Excess baggage is charged per kilogram and can add a meaningful amount to a Mafia or Pemba trip. On Zanzibar, larger aircraft and ferries give you more flexibility. If you plan to dive on Mafia or Pemba, ask your operator about baggage before you book, and consider renting bulky gear locally to save weight.
Island hopping: when two islands cost more than one
Combining Zanzibar with Pemba is possible on a direct small-plane flight. Combining Zanzibar with Mafia usually means flying via Dar es Salaam, which adds a connection and possibly an overnight. Each additional island adds at least one flight segment and two transfers. The flight itself is rarely the main cost; the real cost is the time lost and the extra lodge night if schedules do not align. As a rule, if you have fewer than ten days, one island is better value. With two weeks, a two-island trip can work, but keep the second island close: Zanzibar plus Pemba is simpler than Zanzibar plus Mafia.
Practical questions about island flights and costs
Can you fly directly from Zanzibar to Mafia?
Direct flights are uncommon. Most routings connect in Dar es Salaam, which adds a segment and possibly a wait. Check with local operators for current schedules, and allow a full day for the transfer if you are combining the two.
How much luggage can I take on a flight to Mafia or Pemba?
Light aircraft typically allow around 15 kg per person in soft bags. Excess weight is charged per kilogram. Dive gear often pushes travellers over the limit, so confirm with your operator before booking and pack accordingly.
Is it cheaper to visit one island or two?
One island is almost always cheaper. Each extra island adds a flight and transfers, and the savings from combining are minimal because inter-island flights are priced separately. The exception is a short hop between Zanzibar and Pemba, where the extra cost may be worth it for a different reef and a quieter coast.
