Zanzibar: Prison Island & Nakupenda Boat Tour with BBQ Lunch

Prison Island’s giant Aldabra tortoises are the real draw here. Some are more than 200 years old, and you can walk among them before sailing to Nakupenda Sandbank for warm water, snorkeling, and a generous seafood barbecue.

I like the mix of wildlife and history at Changuu Island, and I like that the long stop at Nakupenda gives you time to swim instead of rushing from one photo stop to the next. Guides such as Salim and Bahama add useful history, good humor, and, on some boats, a singalong on the ride home.

The main catch is the sea. Strong wind or choppy water can spoil snorkeling, and the sandbank can feel crowded when several boats arrive. Also budget the extra $22 conservation and island fee, which is not included in the advertised price.

Key points at a glance

• The tortoise sanctuary is the emotional highlight: You can see enormous Aldabra tortoises up close, including animals said to be more than 200 years old.
• Nakupenda is a tide-shaped beach day: The sandbank changes with the water, so swimming space, timing, and the amount of exposed sand can vary.
• Lunch is a proper barbecue: Seafood, fries or rice, fresh fruit, and soft drinks are included, with chicken and vegetarian alternatives available if requested.
• The guides shape the day: Salim is praised for clear explanations, while Bahama is known for an upbeat manner and singing on the boat.
• The advertised $35 is not the final cost: Add the $22 conservation and Prison Island entry charge paid on the day.
• This is a social boat outing: Smaller groups can feel relaxed, but the landing area and sandbank may get busy.

Why this boat day works so well from Stone Town

This excursion packs two very different Zanzibar experiences into one outing. Prison Island gives you colonial-era buildings, island wildlife, and a memorable encounter with giant tortoises. Nakupenda then shifts the mood to swimming, sun, seafood, and open sea.

That combination is useful if your time in Stone Town is short. You get out on the water without committing to a full diving or fishing trip, and you get a beach afternoon without arranging another transfer across Unguja.

The advertised price is $35 per person. Add the $22 fee payable on the day, and the practical total becomes $57 before any optional transfer costs. That is still fair value for a boat ride, guide, lunch, fruit, soft drinks, snorkeling gear, life jacket, and two major stops.

I would not call this a quiet private-island escape. Boats gather near the sandbank, tents and shaded seating are set up for lunch, and the atmosphere can be lively. If you want a polished resort beach with no other groups around, this is not that. If you want a good-value day with plenty included, it makes much more sense.

Meeting the boat outside Livingstone Beach Restaurant

The standard meeting point is outside Livingstone Beach Restaurant. Look for a guide in a blue or yellow Bureau De Tours shirt. This detail matters because the waterfront can be active, and several boats may be loading at similar times.

Hotel pickup is available if you choose the transfer option. You are asked to wait in the main lobby or entrance area, with your phone available for WhatsApp contact. Airport pickup is also offered, with a representative waiting in arrivals with a name sign.

Bring swimwear, a towel, sandals, and cash. Sandbanks are not the place for heavy shoes, and your feet may get wet during boarding or landing. A waterproof pouch is sensible for a phone, though that is general packing advice rather than an included item.

The tour length is listed as three to eight hours, which is a wide range. In practice, the full experience described here is roughly six hours, with about 30 minutes to Prison Island, 45 minutes onward to Nakupenda, more than three hours at the sandbank, and a short return boat ride. Tide, weather, boat loading, and pickup arrangements can affect the day.

Sailing 30 minutes to Prison Island

The first boat ride is a traditional dhow trip of about 30 minutes. This is part of the experience, not just transport. You get a low view of Stone Town and the sea, with the wind doing most of the work.

Boat comfort can vary. One boat was described as slow, while another return ride met rougher water. The crews are generally attentive, but you should expect an open-air ride rather than a silent, polished cruise. If the sea is choppy, hold onto your belongings and use the life jacket provided.

The guides are a major part of the atmosphere. Salim is often singled out for clear explanations and a calm, helpful manner. Bahama brings more energy and has been known to sing Jambo Bwana on the way back. That sort of local touch can make a basic boat transfer feel more connected to Zanzibar.

Private groups are available. A small shared group can also work well: one group had only six people in its boat, while another had eight. Smaller numbers make it easier to hear the guide and ask questions, though you should not assume every departure will be equally small.

Prison Island, colonial ruins, and giant tortoises

Changuu Island is better known as Prison Island, although the old prison buildings were not used in the simple way the name suggests. The ruins date from British colonial rule and are open to explore during the guided visit.

You get roughly an hour for the island stop. That includes a guided walk, time for photos, wildlife viewing, and some free time. One practical point: the history can feel compressed. If your guide has a lot to explain, the hour goes quickly, so listen closely and ask questions as you walk.

The Aldabra tortoise sanctuary is the island’s main attraction. These are huge animals with slow, deliberate movements and heavily marked shells. The sanctuary is home to some of the oldest and largest tortoises of their kind, including individuals said to be over 200 years old. The population is also described as having grown from four original tortoises to roughly 100.

You may also see peacocks and other animals, with antelopes included among the wildlife listed for the visit. Still, set your expectations correctly. The tortoises are the star. The other animals are an extra, not the reason to book the tour.

There is an important animal welfare issue here. Signs tell people not to touch the tortoises and warn of a $50 fine, but the sanctuary can be crowded and supervision may not always stop people from leaning over or touching them for photos. Please follow the signs, keep your distance, and do not reward bad behavior with your own picture.

A donation request may be made as you leave the sanctuary. Carry small cash if you want to contribute, but understand that donations are separate from the tour price and the mandatory conservation fee.

The 45-minute ride to Nakupenda Sandbank

After Prison Island, the boat continues toward Nakupenda. This leg is listed at about 45 minutes, so it gives you time to settle into the rhythm of the day.

Nakupenda is a low sandbank surrounded by clear, warm water. Its shape and usable beach depend on the tide. At the right moment, it looks wonderfully simple: pale sand, bright water, and boats offshore. At busy times, shade tents, tables, cooking areas, and other groups change the feel.

The sandbank is best understood as a shared day-use beach rather than an untouched desert island. That is not a criticism. The shade and seating are welcome in the strong sun, and the cooking setup means you get a hot meal on site. Just do not expect solitude.

You have about three hours and 15 minutes here, including lunch, swimming, snorkeling, walking, and free time. That is the most flexible part of the excursion. I like that you can choose your pace. Swim if the water is calm, snorkel when visibility allows, or simply sit in the shade with fruit and a soft drink.

Snorkeling depends on wind, tide, and luck

Snorkeling equipment is included: mask, snorkel, fins, and life jacket. The water can be beautifully clear, with coral and small marine life available to see near the sandbank.

But snorkeling is not guaranteed to be excellent. Choppy water can reduce visibility, and strong wind may make the sea uncomfortable. On one outing, guests could swim in a calm section but could not snorkel properly because the waves were too large.

This is a useful distinction. Nakupenda is worth visiting even if the mask stays in the bag, because the swimming and setting are still the main event. But if your main goal is serious reef snorkeling, you should choose a tour built around a dedicated reef site rather than treating this one as a snorkeling expedition.

The sun is strong and shade is limited to the prepared seating areas, so use the free time sensibly. Swim, dry off, eat, and take breaks instead of spending every minute exposed on the sand.

A generous seafood barbecue on the beach

Lunch is one of the strongest parts of the package. The barbecue can include prawns, lobster, fish, chicken, fries or rice, followed by fresh seasonal fruit and soft drinks. Portions are described as generous, and second helpings may be available.

The fruit is cut fresh at the sandbank. Expect tropical selections rather than a fixed restaurant menu. The simplicity suits the setting: grilled food, warm air, bright fruit, and water nearby.

You must tell the operator in advance if you prefer something other than seafood. Chicken is available, and vegetarian meals are advertised as an alternative at no extra charge. However, vegetarian provision can be uneven. One vegetarian diner received mainly rice and fries, while other outings had more satisfactory plant-based choices.

My advice is simple: state your dietary needs clearly when booking and repeat them to the guide at the meeting point. Do not assume that vegetarian means a full separate menu unless it has been confirmed.

Lunch is served around the activity rather than at a fixed indoor restaurant. That means timing follows the beach program and tides. It also means sand, sun, and a busy serving area are part of the meal. I consider that a fair trade for eating freshly cooked food beside the water.

Returning to Stone Town by dhow

The return ride is listed at about 15 minutes, though actual time depends on where the boat is positioned and how quickly boarding goes. It may be the most fun part of the day if the guide is in a lively mood.

Bahama is especially noted for singing, while other guides keep the ride relaxed and social. Sea conditions can change quickly, so the return may be breezy or rougher than the morning crossing. The captain has been praised for handling difficult water, but anyone prone to seasickness should prepare accordingly.

Drop-off options include Livingstone Beach Restaurant, Zanzibar Island, and Abeid Amani Karume International Airport. Confirm your exact choice when booking, especially if you are connecting to a flight. The listed drop-off information does not mean every hotel or airport transfer is automatically included.

What the $35 price really buys you

At first glance, $35 looks unusually low for a full boat day with lunch. The extra $22 changes the calculation, making the required total $57. Even so, the package includes quite a lot:

• Round-trip boat transport
• A local guide
• Prison Island and Nakupenda visits
• Seafood barbecue lunch
• Fresh fruit and soft drinks
• Snorkeling equipment
• Life jacket
• Government taxes listed in the package

Hotel transfers are included only when the transfer option is selected. The conservation and island fee is not included in the headline price. From September 1, 2025, the stated $22 fee covers $10 for marine conservation and $12 for Prison Island entry.

For this total, I see solid value if you want several activities in one day. You would pay more arranging separate boat transport, island entry, food, and snorkeling equipment yourself. The value is weaker if you dislike group beach setups or have no interest in tortoises and light snorkeling.

Free cancellation up to 24 hours before departure and reserve-now, pay-later booking make planning easier. Starting times depend on availability, and the broad duration range means you should check the exact departure details rather than assuming every day follows the same clock.

Who should book this experience

I would recommend it to first-time visitors staying in or near Stone Town, families with older children, couples wanting a full day on the water, and anyone who wants wildlife, history, swimming, and lunch without juggling several bookings.

Children under eight receive an extra 30 percent discount off the adult price. The boat and water activities still require ordinary parental judgment, especially when the sea is rough.

It suits you less if you want a secluded beach, a serious reef trip, or a slow museum-style look at Prison Island. The island visit is short, the sandbank may be busy, and the snorkeling depends heavily on the weather.

The choice of guide can shape the tone. If you want detailed explanations, ask for a guide such as Salim when possible. If you prefer a more playful boat ride, Bahama has a reputation for music and easy conversation. Specific guide requests cannot be guaranteed, but mentioning your preference is reasonable.

Should you book the Prison Island and Nakupenda tour?

Book it if you want a well-priced, full day that covers Zanzibar’s giant tortoises, colonial ruins, sea views, swimming, a beach barbecue, and a little snorkeling. The best parts are the tortoise sanctuary, the fresh lunch, and the unhurried time at Nakupenda.

Skip it if your ideal beach day means silence and empty sand, or if snorkeling quality is your top priority. Also plan around the extra $22 fee, possible rough water, and the shared nature of the sandbank.

For most Stone Town visitors, I think this is a sensible first boat excursion. Just bring swimwear, cash, patience for the tide, and realistic expectations about the word island. Nakupenda is beautiful, but it is a working day beach with boats, tents, cooking, and people. That mix is part of its Zanzibar character.
