Zanzibar: Prison Island and Nakupenda Sandbank

Changuu Island gives this six-hour trip a useful bit of substance before the beach time begins. You’ll see an old prison complex, meet huge Aldabra tortoises from the Seychelles, and then boat out to Nakupenda Sandbank for clear water, snorkeling, swimming, and a seafood lunch.

I like the pairing of history and sea time, and I like that the price includes a private boat transfer, snorkeling gear, water, soda, fruit, and lunch. The main drawback is uneven guiding: Prison Island can feel thin if the explanation is brief, and French-speaking visitors may find the English-only format limiting.

Key points to know before booking

• Giant Aldabra tortoises are the main attraction on Changuu Island, with some weighing up to 200 kilograms and living for many decades.
• Nakupenda gets the longest share of the day, with about four hours for lunch, swimming, snorkeling, and relaxing.
• The seafood meal and tropical fruit are included, along with soft drinks and bottled water.
• Snorkeling equipment and a life jacket are provided, so you do not need to bring your own gear.
• Entry fees are paid separately on the day, an extra cost to add to the advertised $58 price.
• The tour meets at Forodhani in Stone Town and is led in English, with free cancellation up to 24 hours before departure.

From Forodhani to Changuu Island by boat

The trip starts at Forodhani, Stone Town’s waterfront meeting point. From there, you board a dhow for the short crossing to Changuu Island, commonly called Prison Island. The listed boat ride is about 15 minutes, though the full timing can depend on the day’s arrangements and sea conditions.

That short ride is part of the fun. You get open views of the water and the feel of a proper island excursion rather than a land tour with a quick photo stop. I would keep your phone and camera handy, but also protect them from spray. The description promises wind in your hair, and this is one case where that phrase fits the setting.

The boat is a practical choice because Changuu and Nakupenda are reached from Stone Town by sea. You are not spending half the day in a vehicle, and the crossing gives the outing a clear rhythm: history first, beach later.

The tour includes a private boat transfer, but the available information does not explain the boat’s seating capacity or whether the whole excursion is private for your party. If that distinction matters to you, ask BinAboudTours before paying.

Changuu Island and the old prison ruins

Changuu Island is best known for its former prison, built during the British colonial period. The ruins give you a short look at Zanzibar’s past and provide a contrast to the bright water and beach stop that follow.

Expect roughly one hour here for a guided visit, sightseeing, and photographs. This is not a full museum experience with a long series of indoor exhibits. Its value comes from seeing the old structures in place and hearing how the island was used.

I would keep your expectations measured. One French-speaking visitor found Prison Island worthwhile as part of Zanzibar’s story but felt it lacked interest when the guide could not speak French. That is a useful warning. The island’s appeal depends heavily on how clearly your guide explains what you are seeing.

The official tour language is English. If you understand English comfortably, you should be able to follow the visit. If you need French or another language, confirm the arrangements before booking rather than assuming a multilingual guide will be available.

This stop also works well for photographs. You can combine pictures of the ruins with views across the water, but do not let the photo stop crowd out the tortoise sanctuary. The animals are the most distinctive part of Changuu.

Meeting the Aldabra tortoises

The sanctuary is home to Aldabra tortoises brought to Zanzibar from the Seychelles. These are among the largest tortoises in the world, with some reaching around 200 kilograms. They are also known for exceptional longevity, so you are looking at animals whose lives can stretch far beyond the usual human scale.

This is a good stop for families, animal lovers, and anyone who wants more from the island than old stone walls. The tortoises move slowly, but the encounter is not dull. Their size alone makes them memorable, and you can observe them closely and take photographs.

The information supplied for the tour says you can interact with these animals. Treat that as a chance to observe and follow the guide’s instructions, rather than a promise of unlimited handling. With large creatures, respectful behavior matters.

You can also see peacocks on Prison Island. Their bright feathers have made them a symbol of beauty, royalty, and good fortune connected with the island. They add color and movement to a stop that otherwise centers on ruins and tortoises.

I would allow yourself time to look rather than rush from one animal to the next. The tour gives you about an hour on the island, so the guide’s pacing matters. One particularly positive account praised a guide who allowed enough time to visit each part, appreciate the sandbank, and look for fish. That is the kind of pacing that makes a half-day feel worthwhile.

Four hours at Nakupenda Sandbank

After Changuu Island, the boat takes you to Nakupenda Sandbank. This is where the tour shifts from history and animals to sun, water, and food. The schedule allows about four hours here, which is the largest portion of the outing.

The sandbank is described as having clear blue water suited to swimming, snorkeling, and relaxing. You may find the best snorkeling near the area where boats moor, as one detailed account specifically noted plenty of fish on that side. That tip is worth remembering: do not assume the first patch of water you see is the only place to look.

Snorkeling equipment is included: mask, snorkel, and fins. A life jacket is also provided. This makes the tour easier for you if you are not carrying beach gear, though you should still check the fit before entering the water.

The description mentions coral reefs and marine life viewing. You should expect a simple sandbank snorkeling experience, not a specialist reef expedition. Conditions, visibility, tides, and the exact position of the sandbank can affect what you see. Still, four hours gives you time to try the water, come back for lunch, swim again, and slow down.

The sandbank also supplies the quietest part of the day. After the guided island visit, you can choose your own pace. Read that as sunbathing, swimming, sitting with a drink, or walking along the exposed sand when conditions allow. The tour description does not provide details about shade, chairs, changing facilities, or toilets, so ask ahead if any of those are important to you.

Seafood lunch, fruit, and drinks

Lunch is served at Nakupenda and includes seafood, seasonal tropical fruit, soft drinks, and bottled water. A well-prepared meal can make a major difference on a water-based excursion, and the food is one of the most praised parts of this experience.

One French-speaking visitor specifically found that lunch finished the day well. Another praised the seafood as delicious and well cooked, along with the guide’s relaxed timing. Those details suggest that the meal is more than a token snack, though the exact seafood and fruit will vary by season and supply.

You should not expect to choose from a restaurant menu. This is a beach meal tied to the tour’s setup. If you have food allergies or dietary restrictions, contact the provider before the day of the trip. The supplied details do not promise vegetarian, vegan, halal, or allergy-specific options.

The included drinks also help with the heat. Even so, bring extra sun protection. A hat, sunscreen, sunglasses, and a light cover-up are sensible additions for several hours on exposed sand and water. Those items are not listed as included.

What the $58 price really covers

At $58 per person, this tour offers solid value if you want several elements in one half-day: boat transport, a historical island, a tortoise sanctuary, snorkeling, lunch, fruit, and drinks. Booking these pieces separately could require more planning, and the included equipment means you do not have to arrange a snorkel rental.

The price is less attractive if you only want a beach afternoon. A large share of the cost supports the boat transfer and the Prison Island stop, so you should choose this outing because you want both sides of the experience.

Remember that entry fees are not included and are payable on the day. The amount is not supplied, so ask BinAboudTours for the current fee before booking. This is the one notable gap in the advertised price.

The booking terms are useful for uncertain plans. You can cancel up to 24 hours in advance for a full refund, and you can reserve now and pay later. Those policies reduce the risk of committing early, though they do not remove the need to confirm the start time and extra entry cost.

Guide quality can shape the whole day

The guide matters most at Prison Island. Without clear context, the ruins may feel like a quick stop on the way to the beach. With a good explanation, the island becomes a more meaningful part of the tour.

The available feedback is mixed. One person reported that the guide did not arrive at the meeting point, a serious problem that makes communication with the provider important. Other accounts describe a pleasant guide and praise for allowing plenty of time. Another person enjoyed Prison Island but found the Nakupenda guiding weaker.

That pattern suggests you should judge the tour as a combination of strong sights and potentially uneven delivery. BinAboudTours is the named provider, and the advertised guide language is English. Save the meeting point, Forodhani, and confirm the pickup details before departure.

There are 40 ratings with an overall score of 4.1 out of 5. That points to a generally positive experience, but not a flawless one. The strongest praise centers on the meal, the tortoises, the sandbank, and guides who let the day unfold without rushing. The main concerns are guide communication and one reported no-show.

Who will enjoy this Zanzibar excursion?

I would choose this tour if you have one free day in Stone Town and want a compact introduction to Zanzibar’s nearby islands. It suits you especially well if you enjoy mixing a little history with swimming, snorkeling, animals, and a prepared meal.

Families should find the tortoises and peacocks easy to appreciate, though parents should keep an eye on children around the water and boat. The life jackets and included snorkeling equipment help, but the tour still involves a boat ride and several hours outdoors.

It also suits couples and friends who want a simple day at sea without arranging every detail themselves. The four-hour Nakupenda stop gives you more breathing room than a rushed beach visit.

I would hesitate if you need a French-speaking guide, expect a detailed museum tour, or want guaranteed specialist snorkeling instruction. I would also check the entry fee first if your budget is tight, since that cost sits outside the $58 headline price.

Practical details for a smoother day

Meet at Forodhani in Stone Town. Confirm the exact start time because the activity offers different possible starting times depending on availability.

Bring sunscreen, a hat, sunglasses, swimwear, a towel, and a waterproof way to protect your phone. The tour supplies water, soda, fruit, lunch, snorkeling equipment, and a life jacket, but the supplied details do not say that towels or sun protection are included.

Wear something comfortable for moving between boat, island, and sandbank. Keep valuables to a minimum, since this is a water-based outing and the day includes swimming.

Use the free cancellation option if your plans are uncertain, but remember the cutoff is 24 hours before departure. For any language needs, dietary restrictions, or questions about the entry charge, contact the provider before the tour rather than hoping the details will be sorted at Forodhani.

Should you book the Prison Island and Nakupenda tour?

I would book it if you want a well-packed six-hour outing that combines Changuu Island’s ruins and tortoises with Nakupenda’s water time. The seafood lunch, fruit, drinks, boat transfer, and snorkeling gear give the $58 price good practical value, even with entry fees added separately.

I would skip it if your priority is only snorkeling or if you require a guide in French. The historical stop can feel brief, and the quality of the day depends on guide communication and punctual meeting arrangements.

For most visitors staying in Stone Town, this is a sensible way to see two popular coastal sights in one trip. Confirm the meeting details, ask about the entry fee, and keep your expectations realistic. You are buying a varied island day, not a specialist history tour or a dedicated reef expedition.
