Zanzibar : Prison Island Tour

Prison Island’s real draw is not the old prison. It is the slow-moving population of giant land tortoises, some believed to be more than 100 years old. Add a short boat ride from Stone Town, clear coastal water, and a few old buildings, and you have a simple half-day outing with a memorable centerpiece.

I like the easy hotel pickup and drop-off, especially if you are staying outside Stone Town. I also like the chance to see the island with a guide, then walk around on your own after the formal tour. The main caution is value: at $60 per person, this is a lot for a small island if snorkeling is not arranged and the boat is a basic motorboat rather than the traditional dhow described.

Key points at a glance

• The tortoise sanctuary is the main event: See giant tortoises brought from Seychelles in the late 19th century, including animals believed to be over 100 years old.
• The island sits about 20 minutes from Stone Town: The boat ride is short, with no long sea crossing to worry about.
• You get a private five-hour outing: Hotel pickup, transport, a guide, and return service are included.
• The old prison has a complicated story: It was built for isolation, and it was also linked to an Arab owner who intended to hold rebellious slaves, but it was never actually used as a working prison.
• Snorkeling needs checking: Clear water and coral reefs are part of the appeal, but one booking reported that snorkeling was not included.
• Boat arrangements may differ: Some departures use a motorboat instead of the traditional dhow described in the tour details.

The tortoises are why you come

Prison Island is officially known as Changuu Island, but its familiar name points to its past. The island has an old prison building, yet the tortoises are the reason this excursion earns a place in a Zanzibar plan.

These are giant land tortoises imported from Seychelles in the late 19th century. They move through the trees with impressive patience, and their size makes the encounter easy to remember. Some are thought to be more than a century old, though the available information does not give an exact age for each animal.

You will have time to see the tortoise colony during the guided visit. The experience is not a wildlife safari. The animals live in a sanctuary setting, and the island itself is compact. That makes this a good choice if you want a close look at remarkable creatures without spending a full day on the road.

I would plan your expectations carefully. The tortoises are the star attraction, while the rest of the island gives you context, scenery, and time beside the sea. If you book mainly for a large museum, a long historical tour, or a packed schedule, the outing may feel thin.

What the prison buildings really add

The prison gives the island its name, but the story is less dramatic than the name suggests. A prison was built to isolate Zanzibari citizens, and the island had previously been owned by an Arab who intended to use it for rebellious slaves. The prison was never actually used.

That fact matters. You are not touring a former prison filled with documented inmate stories and preserved cells. Instead, you are seeing the buildings and learning how the island was intended to function. The guide’s explanation can turn a brief stop into something more meaningful, but the amount of interpretation may depend heavily on who leads your visit.

The guided walk is listed at about two hours and includes sightseeing, a photo stop, free time, and a walk around the island. You can expect the guide to introduce the buildings and the island’s background, then give you time to look around independently.

That free time is useful. One guide asked in advance if the group wanted to snorkel so he could plan the timing, then allowed the group to explore alone after the formal explanation. That is the right rhythm for a small island visit: a little context first, then room to set your own pace.

Still, guide quality is important here. On one departure, the guide gave only a short explanation and left the group to read the information for themselves. Another guide from a different company ended up helping the group. That is not a reason to reject the tour, but it is a reminder that the human part of this experience can vary.

The 20-minute boat ride from Stone Town

From Stone Town, the trip across the water takes about 20 minutes each way. The ride is short enough to fit comfortably into a half-day, and it gives you a pleasant break from the streets and buildings of town.

The tour description presents the crossing as a traditional dhow ride. At least one departure used a motorboat instead. That difference may matter to you if the boat ride itself is part of the appeal. A dhow suggests a slower, more traditional sailing experience, while a motorboat is usually about getting there quickly.

I would treat the boat type as something to confirm before paying. The available information does not establish that every departure uses the same vessel. You should also ask whether snorkeling equipment, a snorkeling stop, or only free time near the water is included. Clear water and coral reefs are advertised, but one booking specifically found that snorkeling was not included as expected.

The crossing is also the point where the price needs a close look. If your hotel is already in Stone Town, you may not need a long vehicle transfer. One person staying there felt the full price was high because the main cost was the crossing and island visit. If you are based farther away, the included road transport has more practical value.

A five-hour plan, from hotel to island and back

The day begins at your hotel reception. You are asked to be ready five minutes before departure, and the driver should meet you there. The tour vehicle carries the Beach & Safari Holidays logo, which helps you identify the pickup.

For people staying in Stone Town, the drive may be minimal. For hotels in the Unguja South, Unguja North, or Mjini Magharibi regions, the road portion can take up to about an hour in the schedule. That is important when you judge the half-day label. The island visit itself is listed at roughly two hours, but the total outing includes both road transfers and both boat crossings.

You then pass through Stone Town and board the water transport. The crossing to Prison Island takes about 20 minutes. On arrival, the guide leads the island visit, explains the buildings, and takes you to the tortoise area.

The island portion combines several small activities:

• A guided explanation of the old prison and island history
• Time with the giant tortoises
• A photo stop
• Walking and general sightseeing
• Free time
• Possible snorkeling or water time, depending on the arrangement

After the island visit, you return by boat to Stone Town and then by van to your hotel. The overall plan is straightforward, and the included return transfer means you do not need to bargain for a taxi at the end.

How good is the $60 value?

The listed price is $60 per person. That includes hotel pickup and drop-off, an experienced driver, an experienced English-speaking guide, and the guided Prison Island visit. The Prison Island entry ticket is included only if that option is selected, so check the exact package before booking.

For a hotel outside Stone Town, the price is easier to justify. You are paying for the vehicle, driver, boat connection, island access, and the convenience of having the return trip organized. That convenience can be worth a fair amount in Zanzibar, where arranging several separate transfers takes time and can bring uncertainty.

For a Stone Town hotel, the calculation changes. Your road transfer may be short, leaving the boat ride and island entry as the main pieces of the day. If the boat is a motorboat, snorkeling is not included, and the guide provides only a brief explanation, $60 may feel steep.

The strongest value comes when you want a private outing and care about the tortoises. It is weaker if you are mainly looking for a traditional dhow cruise or a full snorkeling trip. I would ask three questions before booking:

• Is the entry ticket included in the price I am selecting?
• Will the boat be a dhow or a motorboat?
• Is snorkeling included, and is equipment provided?

Food is not included, and tipping is optional. Bring your own plan for lunch if the timing matters to you, though the tour is scheduled as a five-hour experience rather than a full-day trip.

Guide quality can shape the whole visit

The best part of this tour depends partly on the guide. A good guide can explain why the island has its name, separate the prison’s intended purpose from what actually happened, and help you understand the tortoise sanctuary rather than simply pointing at the animals.

Several departures handled the practical side well. Pickup was on time, and the driver and guide were described as friendly and helpful. Faisal, a driver, and Hassan, a guide, were specifically praised for being chatty and useful. Those details matter because the trip includes several handoffs: hotel reception, road transfer, boat, island guide, and return transport.

But the service is not guaranteed to feel equally personal every time. One poor experience involved a guide who spoke for only a few minutes, relied on written information, and then spent much of the trip on a phone. The practical lesson is simple: if the explanation feels too short, ask questions directly. Ask about the prison’s history, the tortoises’ origin, and the snorkeling plan before the guide walks away.

The private-group format gives you a better chance to do that. You are not locked into a large group’s pace, and the guide can ask what you want to do with your time. It also means you are paying for a more personal setup, so weak guiding is more noticeable.

Who will enjoy this half-day outing?

I would recommend Prison Island to families, animal lovers, and anyone staying in Zanzibar who wants a short boat trip without committing to a full marine excursion. The tortoises are easy to appreciate, and the island’s manageable size works well when you want a gentle day.

It also suits people who enjoy mixing a little history with nature. The buildings provide a reason to listen, while the tortoises and coast keep the visit from feeling like a purely historical stop.

You may want to skip it if you have already arranged a stronger snorkeling trip, dislike organized transfers, or expect a large prison complex with extensive exhibits. The island is described as a unique place, but it is still a relatively small stop. The central experience is a tortoise sanctuary, a short historical visit, and time near the water.

Combining it with Stone Town sightseeing could make better use of your day, especially if your hotel is far from the city. The tour passes through Stone Town but does not turn that passage into a walking tour. If you want the markets, old streets, and other city sights, plan those separately or ask if they can be added.

Practical details before you book

The tour lasts five hours, with starting times depending on availability. Pickup is offered from Stone Town and hotels in the Unguja North, Unguja South, and Mjini Magharibi regions. Meet the driver at your hotel reception five minutes before departure.

The live guiding language is English, and the group is private. Hotel pickup and drop-off are included, which removes much of the day’s transport work. You should still confirm the entry-ticket option and water activities in writing, since the exact package affects the value.

Cancellation is flexible up to 24 hours before departure for a full refund, and you can reserve now and pay later. Those terms are useful if your Zanzibar schedule is still changing, but they do not resolve the main questions about the boat and snorkeling. Ask those before you commit.

Bring sun protection, drinking water, and a way to protect your phone around the boat. Food is not included. The supplied information does not promise towels, snorkeling gear, or a specific boat style, so do not assume those items are part of the package.

Should you book Prison Island?

Book this tour if you want to see Zanzibar’s giant tortoises, prefer private transport, and like the ease of hotel pickup and return. The tortoise colony is a memorable reason to cross the water, and the short island visit works well as a half-day addition to a longer Zanzibar stay.

Think twice if you are paying $60 mainly for a traditional dhow ride or snorkeling. The boat may be a motorboat, and snorkeling may not be included. For the best value, confirm the ticket, boat, and water arrangements, then consider combining the outing with Stone Town time if your hotel is a long drive away.
