Zanzibar: Prison Island and Nakupenda Sandbank

Prison Island’s giant Aldabra tortoises are the surprise star of this half-day boat trip from Stone Town. You’ll also see the old British-built prison complex, then spend the bulk of your time at Nakupenda Sandbank, where clear water, snorkeling, seafood, and tropical fruit make a pleasant change from Stone Town’s busy lanes.

I like the good mix of history and beach time, and I like that the $58 price includes the boat, guide, snorkeling gear, lunch, fruit, water, and soda. The main caution is guide quality: the tour is advertised with English guidance, but one recent booking reported that the guide never reached the meeting point, while another found the Nakupenda portion less well guided.

Key points to know before booking

• The tortoise sanctuary is the emotional highlight: Aldabra tortoises can weigh up to 200 kilos and live for many decades.
• Prison Island takes about one hour: You’ll see the former prison site and learn about Changuu Island’s past.
• Nakupenda gets about four hours: Swimming, snorkeling, sunbathing, lunch, and fruit make up most of the day.
• Fish may be easiest to spot near the boats: One detailed account found plenty of fish on the side where boats moor.
• The price covers many useful extras: A private boat transfer, guide, mask, snorkel, fins, life jacket, water, soda, fruit, and seafood lunch are included.
• English is the listed tour language: If you need French or another language, confirm before paying.

From Forodhani to Changuu Island by dhow

You meet at Forodhani in Stone Town and set out by dhow, the traditional sailing boat associated with Zanzibar’s coast. The crossing is listed as about 15 minutes, so this is not a long open-sea voyage. Still, the short ride gives you a fresh view of Stone Town and a pleasant start to the day.

I like that the boat ride is part of the activity rather than just a transfer. You feel the wind, leave the city behind, and reach an island with a very different mood. The tour includes a life jacket, which is useful reassurance for anyone who is not fully at ease on a small boat.

The meeting point matters. Forodhani is a clear location, but one booking ended badly when the guide did not appear there. I would arrive early, keep your phone available, and make sure the operator has your current contact details. That is basic advice, but it matters when your transport is a boat and the tide or departure schedule may not wait.

The tour is described as including a private boat transfer. The supplied details do not give a group size, so you should confirm how private the boat will be for your booking if that point matters to you. The listed duration is six hours, long enough to combine both islands without turning the day into a rushed series of stops.

Prison Island and the remains of its old prison

Changuu Island is better known as Prison Island, and the first main stop lasts about an hour. The old prison buildings were erected during the British colonial period. You’ll walk around the ruins, hear about the island’s former residents, and take photographs.

The prison site is worth seeing, but it is not a large attraction. You should think of it as a compact historical stop rather than a full museum visit. One French-language booking found the island less interesting when the guide could not explain it in French. That gives you a useful warning: the quality of the explanation can shape this part of the day.

The historical value is still real. Stone Town is full of layered stories, and Prison Island adds another angle, away from the city streets. The island’s name creates a dramatic expectation, but the visit is fairly short. I would enjoy the ruins, listen closely to the guide, and avoid expecting a long guided tour with many preserved rooms or displays.

The tour description refers to the island as a place where you can learn about its former residents. It does not provide a detailed account of every use of the site, so your guide will be the best source for the local history during the visit. If history is your main reason for booking, ask for a fuller explanation before the boat leaves.

Meeting the giant Aldabra tortoises

The tortoise sanctuary is the most distinctive stop on Prison Island. Aldabra tortoises were brought to Zanzibar from the Seychelles, and these huge animals can weigh as much as 200 kilos. They are also among the longest-living creatures in the world.

This is not a quick wildlife sighting from a boat. You get to see the tortoises on land and interact with them under the sanctuary’s arrangements. The chance to stand near an animal of this size gives the visit its strongest sense of place. You’ll also have time to take photographs.

I like the contrast between the tortoises and the old prison. One tells the island’s human story, while the other gives you a close look at a remarkable animal linked to the wider western Indian Ocean. If you are visiting with children, this is likely to be the easiest part of the trip for them to understand and enjoy.

You may also see peacocks, including males with large, bright feathers. The birds are described as symbols of beauty, royalty, and good fortune on Prison Island. They add color to the stop, though the tortoises are the main reason to allow time here.

Respect the animals and follow the guide’s instructions. The tour specifically allows interaction and photographs, but that does not mean you should crowd or handle the tortoises without direction. The best visit is a calm one, with time to watch how the animals move and feed.

Four hours at Nakupenda Sandbank

After Prison Island, the boat takes you to Nakupenda Sandbank for the largest part of the day. The schedule gives this stop about four hours, including lunch, swimming, snorkeling, marine life viewing, and time to relax.

Nakupenda is a sandbank surrounded by clear blue water. Its appeal is simple: you can step off the boat into a bright coastal setting, swim, sit in the sun, and spend less time following a schedule. The sandbank itself may change in shape and size with the water, so treat it as a natural beach stop rather than a built resort.

The snorkeling equipment is included: mask, snorkel, and fins. A life jacket is also supplied. If you are a confident swimmer, you can use the gear to look for coral reefs and fish. If you prefer to stay close to shore or the boat, you can swim or simply enjoy the water without making snorkeling the center of the visit.

One useful detail is the location of the fish. A detailed account of the outing found plenty of fish on the side where the boats moor. That gives you a practical place to start, though marine life can vary. Ask your guide where conditions are best on the day instead of assuming the fish will be spread evenly around the sandbank.

The listing uses the word beach for Nakupenda, but you should picture a sandbank, not a developed beach town. There are no stated shops, changing rooms, or permanent facilities included in the supplied details. Bring only what you need and protect your phone and camera from water and sand.

Seafood lunch, tropical fruit, and drinks

Lunch is served at Nakupenda and includes fresh seafood, seasonal tropical fruits, and soft drinks. Bottled water is also included. This is a useful part of the price because food and drinks can be awkward to arrange on a remote-feeling sandbank.

The meal is described as a seafood barbecue, with fruit served afterward or alongside it. One detailed account praised the food as delicious and well prepared, while another specifically found that lunch finished the day well. I would consider the meal a genuine strength of the tour, especially after swimming and snorkeling.

You should remember that the menu is not specified. If you have allergies, dietary restrictions, or do not eat seafood, ask the operator what alternatives are available before booking. The provided information confirms seafood, fruit, water, and soda, but it does not promise a vegetarian, vegan, or special-diet menu.

The setting does part of the work. Eating beside clear water is more memorable than eating in a restaurant, but it is also less formal. You may be eating outdoors with sun, sand, and boat activity nearby. Pack sun protection and keep expectations focused on a fresh island meal rather than restaurant service.

What the $58 price really buys you

At $58 per person, this tour offers a solid package for a six-hour outing. The price includes the boat transfer, guide, snorkeling equipment, life jacket, seafood lunch, seasonal fruit, bottled water, and soda. That is a useful list of inclusions for a day that combines transport, sightseeing, food, and water activities.

The value is strongest if you plan to do both Prison Island and Nakupenda anyway. Booking transport, a boat, snorkeling equipment, and lunch separately could take more planning. Here, the day has one basic structure, and you can spend your energy enjoying the islands rather than arranging each piece.

Entry fees are not included and must be paid on the day. The amount is not provided, so budget extra rather than treating $58 as the complete final cost. Ask about the entry charge before departure if you need a firm total.

The value is less clear if you mainly want a serious historical tour. Prison Island gets only about one hour, and the quality of the history talk appears to depend heavily on the guide. The tour makes more sense for someone who wants a broad half-day outing with wildlife, sea time, and lunch, with a small historical stop included.

Guide quality and language concerns

The listed tour language is English, and a live guide is included. That should work well if you can follow spoken English and want basic explanations at both stops. The guide is important at Prison Island because the ruins alone do not tell the full story.

You should not book this as a French-language tour unless the operator confirms that arrangement. One booking specifically found the Prison Island stop less appealing when the guide did not speak French. The information supplied names no individual guide, so there is no reliable guide name to request.

The feedback is mixed rather than uniformly negative. One booking described the guide and the tour as very pleasant, and another praised a guide who allowed plenty of time to visit, enjoy the sandbank, and look for fish. On the other hand, one person found the Nakupenda guidance weak, and another reported a complete failure at the meeting point.

That makes communication your best safeguard. Confirm the meeting point at Forodhani, departure time, language, and the contact method before the day of the tour. If you have limited time in Zanzibar, a missed departure is a bigger problem than a merely average explanation.

Who will enjoy this island combination

I would recommend this outing to you if you want several Zanzibar highlights in one manageable day. It suits couples, families, and first-time visitors who want wildlife, a little history, swimming, snorkeling, and lunch without arranging separate trips.

It is also a good fit for anyone who enjoys a relaxed schedule at the water. Four hours at Nakupenda gives you time to swim, use the snorkeling gear, sunbathe, eat, and pause. You are not being moved from one photo stop to the next every few minutes.

Families should find the tortoises and peacocks especially appealing, though the supplied information does not specify child pricing or age rules. Ask the operator about those details before booking. The tour is marked wheelchair accessible, but the information does not explain the exact boat boarding arrangements or movement on the sandbank, so confirm those points if needed.

I would be more cautious if you dislike boats, want a long museum visit, or need a guaranteed specialist guide. The dhow ride is short, but the boat remains central to the day. Prison Island is compact, and the English-only listing may not suit every language need.

Practical ways to make the six hours better

Arrive at Forodhani early. You want time to find the meeting point without rushing, especially since one booking had trouble locating the expected guide. Keep the operator’s contact details at hand.

Use the first hour well on Prison Island. Look closely at the prison ruins, listen for the island’s story, and leave enough time for the tortoise sanctuary and peacocks. This stop is brief, so it rewards attention more than a hurried walk-through.

At Nakupenda, ask where snorkeling is best before putting on the mask and fins. The fish may be especially easy to spot near the side where boats moor, but your guide can point out the better area that day.

Bring sun protection and a secure way to carry personal items, since the afternoon is spent outdoors on a sandbank. The tour provides water and soda, but it does not list sunscreen, towels, or dry bags among the inclusions.

Keep some flexibility in your expectations. The sandbank is a natural setting, and guide quality can vary. If the lunch, clear water, tortoises, and boat ride appeal to you more than polished interpretation, the outing is likely to feel worthwhile.

Should you book this Prison Island tour?

I would book it if you want an easy blend of Zanzibar history, large tortoises, snorkeling, and a seafood lunch for $58. The tortoise sanctuary and the four-hour Nakupenda stop give the day more substance than a quick island photo trip, and the included equipment and food make the price reasonable.

I would pause before booking if you need a non-English guide, a detailed historical tour, or a perfectly reliable meeting arrangement without confirming details first. Contact BinAboudTours before departure, verify the Forodhani meeting point, ask about entry fees and language, and then make your choice.

For most people, the best reason to go is the balance: one short historical stop, one memorable animal encounter, and several hours beside clear water. It is a practical Zanzibar day out, with enough variety to keep the experience from feeling repetitive.
