Zanzibar: Half-Day Private in Prison Island Tours

Prison Island’s biggest surprise is not the old prison building. It is the giant Aldabra tortoises wandering around the sanctuary, some weighing about 200 kg and said to be more than 150 years old. You reach the island by private speedboat, then spend time with the tortoises, see peacocks, and hear why this small island was once called Prison Island.

I like the simple shape of this trip: three hours, private group, and a short boat ride from Stone Town. I also like that the visit gives you a choice between snorkeling around the coral-fringed shore and simply resting on the beach with fresh fruit and water. The main consideration is time. Three hours passes quickly, especially if you want both the guided visit and a good swim.

Key points at a glance

• Giant tortoises from the Seychelles: Meet a large colony, touch the tortoises, and take photos of animals said to be over 150 years old.
• A short ride from Stone Town: The island sits about 5 km from shore, with the listed speedboat journey taking about 30 minutes.
• A private English-speaking guide: You receive a guided visit rather than being left to wander alone.
• A former prison site: The building dates from 1893 and was intended for violent prisoners from the mainland and people with illness.
• Snorkeling or beach time: Use the remaining time to look around the coral near shore or relax in the sun.
• Useful inclusions: Hotel pickup and drop-off, a large bottle of water, and fresh fruit are included.

A quick boat ride from Stone Town

This half-day outing begins with pickup in the Unguja North Region, while the boat departure is described as being from the shores of Stone Town. Confirm the exact pickup point when you book, since the wording covers more than one part of the island.

From the shore, you take a speedboat toward Prison Island. The listed boat time is about 30 minutes, and the island lies roughly 5 km from Stone Town. That makes this a manageable outing if you want to add an island visit without giving up a full day.

The crossing is part of the fun, but it also affects comfort. The tour is not suited to pregnant women, people with back problems, or anyone with a pre-existing medical condition. Oversize luggage is not allowed, so bring only what you need for a short boat ride and beach visit.

Meeting the giant tortoises

The tortoise sanctuary is the main event. Giant tortoises were brought from the Seychelles in the late 19th century, and the colony includes animals said to be more than 150 years old. Their average weight is given as about 200 kg, so these are not small zoo tortoises you can easily overlook.

You can touch the tortoises and take photos. That close contact is a major reason to choose this trip, especially if you enjoy wildlife but do not want to spend a full day on safari. The animals move at their own pace, which is to say, very little pace at all. Give yourself time to watch them rather than rushing through for a single picture.

The guide helps explain what you are seeing and keeps the visit organized. The available feedback gives particular credit to the guide for being friendly, capable, and punctual. No guide name is provided, but the tour is conducted in English.

Bring patience and a respectful attitude. The chance to touch the tortoises is part of the experience, but you should follow the guide’s instructions and handle the animals gently. The information provided does not specify feeding rules, so do not assume you may give them food.

Understanding why it is called Prison Island

The island’s name comes from its former use. The prison was built in 1893 and was intended to house violent prisoners from the mainland as well as people with illness. The building is now owned by a hotel, but the site remains an important part of the visit.

This is not a long museum tour with a large collection of exhibits. Instead, you get a guided look at a compact historic site and an explanation of how the island was meant to function. That makes the guide important. Without context, you might see only old walls and a pleasant beach. With the story, the island’s name makes more sense.

The contrast is striking: the island is now linked with sunshine, tortoises, swimming, and peacocks, yet its original purpose was far less inviting. I like that the tour puts the pleasant scenery beside this harder piece of Zanzibar’s past rather than treating the island as only a photo stop.

Peacocks, coral, and a choice of how to spend your time

Prison Island is also home to peacocks. They add another easy photo opportunity and give the island more character, though the tortoises are clearly the main attraction.

After the guided portion, you can snorkel around the coral that fringes the island. The information provided does not promise particular fish, visibility, or snorkeling equipment, so ask what is supplied before you go if snorkeling is important to you. The tour description confirms the chance to snorkel, but it does not list masks, fins, or other gear among the included items.

You can also choose not to snorkel. Sit on the beach, enjoy the warm sun, and use the included water and fresh fruit. This is a good feature for a private group because not everyone has to follow the same plan. One person can look for marine life while another takes a quieter break.

Still, keep an eye on the clock. The total trip lasts three hours, including the boat ride, guided visit, and return. If you want a long swim, a careful look at the prison, extended tortoise time, and photographs, the schedule may feel tight.

What the private format changes

A private group gives you more control than a large shared excursion. You can ask questions about the island, spend longer with the tortoises, or move on when you have seen enough. The guide can also explain the site in English rather than leaving you to read a short sign and guess at the rest.

Private does not mean unlimited time. The speedboat journey takes about 30 minutes each way, leaving roughly two hours on or around the island. The exact split depends on pickup and boat timing, so decide before arrival what matters most to you.

I would put the tortoise sanctuary first, then the former prison, then snorkeling if time allows. That order protects the parts of the trip that are unique. Beach time is easy to enjoy, but the chance to stand beside a 200 kg tortoise is less common.

Is $100 per person fair value?

At $100 per person, this is not the cheapest way to spend three hours in Zanzibar. The value comes from the private arrangement, speedboat transport, hotel pickup and drop-off, a live English-speaking guide, water, and fresh fruit.

You are paying for a focused outing rather than a full-day package. There is no meal included, and food and drinks beyond the listed water and fruit are not covered. If you expect lunch, bring money or confirm your options before departure.

The price makes the most sense for a couple, family, or small group that values privacy and a short schedule. It is less appealing if you are happy to share a boat, spend only a few minutes at the sanctuary, or arrange transport independently.

The tour has a 5.0 rating from four verified bookings. The praise centers on the full experience, the guide, and punctual service. That is a small sample, so I would treat it as encouraging rather than absolute proof. Still, punctual pickup matters on a three-hour trip, since a late start quickly cuts into island time.

What to bring and what to leave behind

Pack lightly. Oversize luggage is not allowed, and there is no reason to bring a large bag for this short outing.

Useful items include:

• Swimwear and a towel if you plan to snorkel or swim
• Sun protection for the boat and beach
• A phone or camera for the tortoises, peacocks, and island views
• A small amount of personal water or other drinks if you want more than the included bottle
• Comfortable clothing for a boat ride and time outdoors

The tour includes a large bottle of water and fresh fruit. Food and other drinks are not included, so do not count on a meal during the trip.

Making fire is not allowed. That rule is simple but important. This is a protected island setting, not a place for cooking or a beach barbecue.

Who will enjoy this Prison Island trip?

I would recommend it most to people staying near Stone Town who want a compact island outing with wildlife and history. It also suits families and small private groups that do not want to match the pace of a large tour.

You will likely enjoy it if you want:

• Close contact with giant tortoises
• A short boat trip instead of a full-day cruise
• A guided explanation of the former prison
• The freedom to snorkel or relax
• Hotel pickup and return included

I would think twice if you need a long, slow beach day, a full meal included, or a detailed museum-style history tour. The attraction is compact, and three hours is enough for a taste rather than a complete island day.

People with back problems, pregnant women, and anyone with a pre-existing medical condition should not book this activity according to the stated restrictions. The speedboat crossing and beach setting may not suit everyone.

Booking details that matter

The activity is listed at $100 per person and lasts three hours. Starting times depend on availability. The group is private, and the live guide speaks English.

You can cancel up to 24 hours before departure for a full refund. A reserve-now, pay-later option is also available, which helps if your Zanzibar schedule is still moving around.

Before paying, confirm the pickup point. The details refer to pickup in the Unguja North Region and departure from Stone Town, so you will want the exact meeting arrangement. Also ask about snorkeling equipment if you do not plan to bring your own, since it is not listed among the included items.

Should you book it?

Book this Prison Island tour if you want a short, private Stone Town excursion built around giant tortoises, a curious historic site, and a little time by the sea. The friendly, punctual guide service and simple logistics add real value, while the private format keeps the pace flexible.

Skip it if you want a full beach day, a substantial meal, or a longer snorkeling trip. For most people, the best reason to book is the tortoise sanctuary. The old prison gives the outing its story, but those enormous, slow-moving animals are what you will remember on the boat ride back.
