Zanzibar: Prison Island & Nakupenda Boat Tour with BBQ Lunch

Prison Island’s enormous Aldabra tortoises are the main reason to go, but Nakupenda Sandbank gives this outing its holiday glow. You sail from Stone Town in a traditional dhow, walk among tortoises that may be more than 200 years old, then spend several hours swimming, snorkeling, and eating lunch beside clear turquoise water.

I like the friendly local guides, especially Salim and Bahama, who are often praised for their clear explanations and good humor. I also like the generous lunch, with seafood, chicken alternatives, fries or rice, and freshly cut tropical fruit. The main catch is the extra $22 conservation and entry fee, which is not included in the advertised $35 price.

Key points before you book

• Giant tortoises: See Aldabra tortoises at Prison Island, including some said to be more than 200 years old.
• Two very different stops: Prison Island supplies history and wildlife, while Nakupenda offers swimming, snorkeling, and beach time.
• Food is a real part of the experience: Expect grilled seafood, fruit, soft drinks, and alternative meals if requested ahead.
• A dhow, not a speedboat: The ride is scenic and breezy, but some boats are slow and the sea can turn choppy.
• Bring cash for the $22 fee: The added charge covers marine conservation and Prison Island entry.
• Best for an easy Stone Town day: You get transport, a guide, lunch, equipment, and several hours by the sea in one outing.

From Stone Town to Changuu Island by dhow

The day begins outside Livingstone Beach Restaurant, unless you select hotel or airport pickup. Look for a guide in a blue or yellow Bureau De Tours shirt. If you choose a transfer, wait in your hotel lobby or entrance area, or at the airport arrivals area with your phone available for contact.

The boat ride to Prison Island takes about 30 minutes. A dhow gives you an open-air view of Stone Town fading behind you, with salt air and plenty of wind. You may get splashed, so sandals and a small bag that handles water are sensible choices.

This is not a polished yacht excursion. Boats gather near the islands, boarding can feel busy, and one boat may be slower than another. That is part of the local working harbor feel, but it also means you should not expect military timing or a silent cruise.

The ride back and forth is part of the pleasure. Guides sometimes sing on the return journey, and Jambo Bwana has become a memorable finish for many groups. If you prefer a quiet, private boat, ask about the private-group option before booking.

Prison Island’s tortoises and colonial ruins

Changuu Island, better known as Prison Island, is a compact stop with two clear draws: the old prison buildings and the tortoise sanctuary. The planned visit lasts about an hour, so you get a useful introduction rather than a slow museum visit.

The prison was built during the British colonial period, though the island’s past includes other uses and former residents. Your guide explains the site while you walk through the surviving ruins. Salim is particularly good at making the history easy to follow, while Bahama has also earned praise for mixing facts with humor.

Allow yourself time to look up from the buildings. The island is carpeted with trees, and peacocks and other animals may appear around the paths. Antelope sightings are also listed as part of the wildlife experience, though wildlife is never guaranteed on a timed group visit.

The tortoise sanctuary is the emotional center of this stop. Aldabra tortoises are among the largest tortoises in the world, and some individuals here are said to be more than 200 years old. You can see smaller tortoises as well as the huge, slow-moving adults, which makes the visit interesting for children and adults alike.

There is an important ethical point here. Signs warn visitors not to touch or climb on the tortoises, but supervision can be uneven when the sanctuary is crowded. I would treat the animals as wildlife, keep your hands off, and avoid blocking their path for photographs. The sanctuary also asks for donations as you leave, so keep a little cash if you want to contribute.

The hour can feel short if you want to read every sign, ask many questions, and spend time with the animals. One practical tip is to listen closely when the guide begins the history talk, then use your free time for photographs and the tortoise area. If history is your main interest, this tour may feel brisk.

Nakupenda Sandbank, swimming, and snorkeling

After Prison Island, the dhow continues toward Nakupenda Sandbank. The ride takes about 45 minutes, followed by roughly three hours and 15 minutes at the sandbank. Tides shape the experience, and the amount of exposed sand can change, so do not picture a fixed beach with permanent buildings.

Nakupenda is a place for simple pleasures: swim, walk, lie in the sun, take photographs, and watch the water shift around the sand. The colors are a major reason this stop is so popular. On a calm day, the water can be remarkably clear and warm, with bright turquoise shallows around the pale sand.

Snorkeling equipment is included: mask, snorkel, and fins. A life jacket is also available. The water conditions matter more than the equipment, though. Strong wind and waves can reduce visibility or make snorkeling disappointing. On rougher days, one side of the sandbank may remain calm enough for floating and swimming even when the snorkeling area is not worthwhile.

That flexibility is useful. You do not have to spend the whole stop in the water. Some people swim or snorkel before lunch, while others stay under the shade, walk the sandbank, or settle in with a drink. Seating and shaded tents are available, though the setting can become crowded because several tours use the sandbank.

The sandbank is beautiful, but it is not an untouched private island. You may see boats arriving, groups sharing the picnic area, tents, music, and several barbecues operating nearby. If you want solitude, book a private group or ask about the quietest departure time. If you like a social beach atmosphere, the activity around the sandbank adds energy.

The seafood barbecue and fresh fruit

Lunch is served at Nakupenda and is one of the strongest parts of the day. Expect a seafood barbecue with items such as prawns and lobster, along with fries or rice, depending on the menu that day. Chicken can be arranged for people who do not eat seafood, but tell the operator in advance.

Fresh seasonal fruit follows or accompanies the meal. Watermelon, pineapple, and other tropical fruit are cut on site, which is a nice touch in the heat. Soft drinks are included as well. Several portions are generous enough for second helpings, so this is not a token picnic lunch.

Vegetarian meals are available in principle, but the quality may depend on what has been arranged. One vegetarian meal was reported as rice and fries, while another group received sufficient alternatives. I would state your preference clearly when booking and repeat it by WhatsApp before the day. Do not assume that a full separate vegetarian menu will appear automatically.

Lunch is prepared in a basic beach setting, not a restaurant kitchen. That is part of its appeal. You eat close to the water, with sand, sun, and the smell of grilling seafood around you. Bring sandals rather than walking barefoot everywhere, and carry cash for the conservation charge and any optional donation at Prison Island.

Guides, group size, and the pace of the day

The guide can shape this experience more than any single attraction. Salim is frequently praised for clear explanations, patience, and a calm manner. Bahama is known for creating a cheerful mood, helping people feel included, and keeping the boat ride lively. Guides speak English, Italian, Spanish, French, German, Swahili, Russian, and Korean.

The usual format is a shared group, though private groups are available. Smaller boats can make a difference. A group of six or eight gives you more room and makes it easier to hear the guide, while larger groups can feel more crowded at the tortoise sanctuary and sandbank.

The full outing can take about six hours, though the advertised duration ranges from three to eight hours depending on the selected option and conditions. The stated schedule allows about one hour at Prison Island, 45 minutes on the next boat leg, and more than three hours at Nakupenda. Return travel takes about 15 minutes in the final leg, but actual timing can change with tides, sea conditions, and transfers.

The day is relaxed rather than rushed, but it is still a full sun-and-water outing. You will want a towel, swimwear, sandals, cash, and a way to protect your phone. A hat and sunscreen are sensible additions, though only the first group of items is specifically required.

What the $35 price really covers

At $35 per person, the package looks inexpensive because it combines boat transport, a guide, lunch, fruit, soft drinks, snorkeling gear, a life jacket, and government taxes. Hotel pickup and drop-off are included only if you select the transfer option, so check the exact booking choice before assuming transport is covered.

The important price detail is the separate $22 charge. From September 1, 2025, this covers $10 for marine conservation and $12 for Prison Island entry. That brings the practical total to about $57 per person before any optional spending.

Even at that total, the value is solid if you want both islands in one day. Paying separately for a boat, guide, food, snorkeling gear, and transfers would require more planning. The value is weaker if you only want a quiet beach afternoon, since Nakupenda can feel crowded and the sandbank is shared with other groups.

The activity also offers free cancellation up to 24 hours before departure and a reserve-now, pay-later option. Those policies help if your Stone Town schedule is not fixed, but sea conditions still matter on the day.

Who should book this Stone Town boat trip?

I would choose this tour if you have a short stay in Zanzibar and want a broad sample of the coast near Stone Town. It combines wildlife, colonial-era buildings, a dhow ride, swimming, snorkeling, and a cooked lunch without requiring several separate bookings.

Families can benefit from the short boat rides and large tortoises, though young children need close supervision around the water, boats, and animals. Couples will like the sandbank setting, especially if they choose a smaller or private group. Food-focused visitors should be happy with the barbecue, provided dietary needs are stated early.

I would hesitate if your priority is serious snorkeling. Nakupenda can offer clear water and marine life, but wind and waves may reduce visibility. I would also hesitate if you dislike shared beach facilities, lively groups, or a flexible island schedule.

Should you book it?

Book it if you want an easy, good-value day from Stone Town with two distinct stops. The tortoises are the memorable wildlife feature, Nakupenda supplies the swimming and photographs, and the barbecue makes the long day feel well fed.

Before paying, add the $22 fee to your budget, confirm your pickup choice, request a vegetarian or chicken meal if needed, and check the weather and sea conditions. Choose this trip for variety and friendly guiding, not for solitude or guaranteed snorkeling. For most people staying near Stone Town, it is a well-rounded day on the water.
