Zanzibar: Prison Island and Nakupenda Sandbank

The tortoises are the real stars. This six-hour boat trip from Stone Town combines Prison Island’s old ruins with Nakupenda Sandbank’s clear water, snorkeling, and a seafood lunch. I like the easy 15-minute crossing and the chance to see Aldabra tortoises up close. I also like that the price includes a private boat transfer, guide, equipment, fruit, drinks, and lunch.

The main drawback is uneven guiding. One booking ended with the guide failing to meet at Forodhani, and the Nakupenda portion can feel less well explained than the Prison Island visit. Entry fees are extra, and the island itself may feel brief if you are mainly interested in beaches rather than Zanzibar’s past.

Key points to know before booking

• The boat ride takes about 15 minutes: The short crossing from Stone Town gives you a quick taste of sailing without turning the trip into a long sea journey.
• Prison Island mixes history and wildlife: You visit former prison ruins, then meet Aldabra tortoises that can weigh up to 200 kilograms.
• Nakupenda takes up most of the day: Expect about four hours for swimming, snorkeling, lunch, fruit, and time on the sandbank.
• Lunch is a strong part of the package: Fresh seafood, seasonal tropical fruit, bottled water, and soft drinks are included.
• Guiding quality matters: English is the stated tour language, so French-speaking visitors should not expect a French guide.
• The $58 price is fairly solid: It covers transport, a guide, snorkeling gear, food, and drinks, but you still pay island entry fees separately.

Setting out from Forodhani in Stone Town

The meeting point is Forodhani, the waterfront area in Stone Town. This is a sensible departure point because Prison Island sits offshore, and the boat ride is the natural way to reach it.

The crossing takes about 15 minutes by dhow. That is long enough to enjoy the sea air and views, but short enough that even people who are not keen on boat trips should find it manageable. The description promises wind in your hair, and this part of the outing is simple but pleasant: you leave the old town behind, settle into the boat, and reach Changuu Island without spending half the morning in transit.

You receive a life jacket and bottled water. Snorkeling equipment, including a mask, snorkel, and fins, is also included for later use. I would still treat the boat ride as a practical transfer rather than a full sailing excursion. The real sightseeing begins once you reach the island.

Because the tour is sold as a six-hour experience, timing at the meeting point matters. One serious complaint involved a guide not arriving at the stated meeting place. I would confirm the meeting instructions with BinAboudTours before departure and arrive early, especially if you are staying in or near Stone Town.

Prison Island’s ruins and its giant tortoises

Changuu Island is better known as Prison Island, a name that gives the first stop its character. The British colonial authorities built the old prison, and you walk through the remaining ruins with a guide during roughly one hour of sightseeing.

Do not expect a grand fortress or a long museum visit. The attraction is compact. Its value comes from the story of the island and the contrast between its former use and its current role as a wildlife stop. If your guide explains the background well, the ruins give you a useful glimpse into Zanzibar’s colonial past and the island’s former residents.

The guiding can make or break this section. One French-speaking visitor found the stop less appealing without a French guide, while another rated Prison Island as the best part of the trip. English is the stated language, so you should book with that in mind. If you understand English comfortably, you are more likely to get the full benefit from the explanation.

The tortoise sanctuary is the more memorable part for many people. The Aldabra tortoises were brought to Zanzibar from the Seychelles. They are among the largest tortoises on earth, with some weighing up to 200 kilograms, and they are known for remarkably long lives.

You can see them at close range, interact with them, and take photographs. That makes the visit particularly appealing for families and anyone who enjoys wildlife more than ruins. The animals are slow, heavy, and wonderfully odd. They are not a quick photo prop, but a central part of the stop.

Prison Island also has peacocks with large, bright feathers. They add a splash of color to the visit and are linked with beauty, royalty, and good fortune on the island. The combination of tortoises, peacocks, and old stone buildings gives this stop more variety than the name suggests.

Still, keep your expectations measured. You are not spending a full day exploring a large island. The guided visit lasts about an hour, and some of that time is devoted to taking pictures and seeing the animals. If you want long historical commentary, ask questions and stay close to the guide.

Four hours at Nakupenda Sandbank

After Prison Island, the boat continues to Nakupenda Sandbank, where the pace changes completely. The remaining four hours are set aside for swimming, snorkeling, sunbathing, lunch, and time around the water.

The sandbank is described as having crystal-clear blue water. The appeal here is less about organized sightseeing and more about having a long, open break by the sea. You can swim, relax, and spend time looking for marine life around the coral areas.

Snorkeling equipment is included, which saves you from arranging a separate rental. The tour description points to coral reefs and marine life, and one particularly useful tip is to look around the area where the boats are moored. That side can have plenty of fish. Conditions in the water can vary, so I would see snorkeling as a chance to explore rather than a guaranteed major reef expedition.

The sandbank stop has received mixed impressions about guiding. The water and setting are the main attraction, but the guide may not provide the same level of attention here as at Prison Island. If you want to get the most from the snorkeling, ask where the best fish and coral areas are before heading into the water.

You also get free time, which is important. A four-hour stop can feel generous if you want a slow afternoon, but long if you prefer constant sightseeing. Bring patience for the rhythm of a beach day: swim, dry off, eat, rest, and swim again.

The sandbank itself is also likely to change with tides and conditions. The provided information does not give a fixed shape or exact size, so I would not plan around a particular strip of exposed sand. Think of it as a shallow-water beach stop reached by boat, with the day built around the sea.

Seafood lunch, fruit, and drinks

Lunch is included and is one of the stronger reasons to consider this package rather than arranging transport alone. You receive a fresh seafood meal, seasonal tropical fruit, bottled water, and soft drinks.

The meal is served alongside the Nakupenda stop, so you do not need to leave the beach area to find food. That keeps the day simple and gives you more time in the water. One French visitor specifically found the lunch delicious and well prepared, while another said it finished the day perfectly.

The menu is not specified, so you should not book expecting a particular seafood dish. The same applies to the fruit, which changes by season. What is clear is that the lunch is part of the planned experience, not an optional snack.

This is also where the tour feels most social and relaxed. After the history and wildlife at Prison Island, a shared seafood meal gives the excursion a local food element. It is not a formal restaurant experience, but it fits the setting.

If you have dietary restrictions, the supplied information does not state whether alternatives are available. Ask BinAboudTours before booking rather than assuming the lunch can be changed.

What the $58 price really covers

At $58 per person, the tour offers reasonable value if you want both islands in one outing. You are paying for a private boat transfer, an English-speaking guide, snorkeling equipment, a life jacket, water, soft drinks, fruit, and seafood lunch.

That package matters in Zanzibar because arranging each part separately can become inconvenient. You would need to organize a boat, find a guide, arrange snorkeling gear, and sort out food at the sandbank. This experience bundles those pieces into a half-day trip from Stone Town.

The price is less attractive if you only want to sit on a beach. Nakupenda is the main relaxation stop, but you also pay for the Prison Island visit and its historical and wildlife content. If the tortoises and old ruins do not interest you, a beach-focused outing may suit you better.

Remember that entry fees are not included. The amount is not provided, so you should budget for an additional payment on the day. That extra cost does not automatically make the tour poor value, but it means the advertised price is not the full final cost.

The private boat transfer is worth noting. The information does not state the number of people in the boat, so I would not assume a completely private, quiet sailing experience without checking. Still, private transfer is a useful inclusion and may give you more direct transport than a standard shared excursion.

The guide can shape the entire day

This experience depends heavily on the guide. At Prison Island, the guide can explain the old prison, introduce the tortoises, and give the visit a clear flow. At Nakupenda, the guide can point out good snorkeling areas and help make the long beach stop feel purposeful.

The feedback is not uniformly strong. Several bookings rated the tour highly, including comments praising the guide’s friendly manner and willingness to let people spend the time they needed at the sandbank. One person described the whole activity as excellent, and another called it very pleasant from start to finish.

But there are limits. The Nakupenda guide was considered weaker by one visitor, and the lack of French guidance reduced the appeal of Prison Island for another. The most serious issue was the report of a guide missing the meeting point altogether.

I would book this tour for its places and included food, while treating the guide as an important variable. Confirm the language, meeting point, and departure details in advance. If communication is smooth, the day should be easy to enjoy.

Who will enjoy this Zanzibar boat trip

I would recommend it to first-time visitors staying in Stone Town who want a compact introduction to Zanzibar’s nearby coastal attractions. In six hours, you get history, animals, boating, snorkeling, swimming, and lunch without needing a separate full-day plan.

Families may especially like the tortoises and peacocks. The boat ride is short, and the itinerary offers different kinds of activity, so children do not need to spend the whole day doing one thing. Parents should still keep an eye on children around the water and use the provided life jackets as appropriate.

It also suits couples and small groups who want a relaxed day with some structure. The four-hour Nakupenda stop leaves room for swimming and resting rather than forcing you from one sight to the next.

I would be more cautious if you want a serious history tour, a large coral reef experience, or highly detailed guiding in a language other than English. Prison Island is compact, and the snorkeling is presented as one part of a mixed beach day, not as a specialist marine excursion.

Practical details that affect your choice

The full duration is six hours, with about 15 minutes by dhow to Prison Island, about one hour at Prison Island, and about four hours at Nakupenda Sandbank. The stated starting location is Stone Town, with the meeting point at Forodhani, and the trip returns there.

English is the listed tour language. The experience is described as wheelchair accessible, though the information does not explain the exact boat or shoreline arrangements. If you use a wheelchair, ask BinAboudTours how boarding and movement at both islands are handled.

Cancellation is free up to 24 hours before departure, and you can reserve now and pay later. Those terms are useful if your Zanzibar schedule may change, but they do not remove the need to confirm the meeting point.

Pack for a day around water. The tour supplies a life jacket, snorkeling gear, water, soft drinks, fruit, and lunch, but the supplied information does not mention towels, sun protection, or a change of clothes. I would plan accordingly without assuming those items are provided.

Should you book Prison Island and Nakupenda?

Book it if you want a well-priced mix of Zanzibar history, unusual wildlife, snorkeling, and a seafood lunch in one six-hour outing. The Aldabra tortoises are the strongest reason to go, while Nakupenda gives you enough time to swim, rest, and enjoy the coast without rushing.

Think twice if your priority is polished guiding, a French-language tour, or a full historical tour of Prison Island. The experience has earned plenty of high marks, but the guide quality is not completely consistent, and entry fees cost extra.

My practical choice would be to book after confirming the Forodhani meeting instructions and English-language guiding. For $58, the included boat, food, drinks, equipment, and two distinct stops make this a sensible Stone Town day trip, as long as you see it as a flexible beach-and-sightseeing outing rather than a perfectly scripted tour.
