A Half Day Private Prison Island Tour

The biggest draw here is the Aldabra giant tortoise sanctuary, where you can get close to enormous tortoises and take photographs. I like the short boat ride from Stone Town and the fact that your private guide can help shape the visit around the tortoises, ruins, or a swim. I also like that transport, taxes, water, and pickup are included.

The main catch is the beach. It is small, and several boats may gather there, so swimming can be awkward. The old prison ruins are also modest, and bad weather can shorten the outing without making the price any lower.

Key Points at a Glance

• Giant tortoises are the main event: See Aldabra tortoises brought to Zanzibar as a gift to the Sultan.
• A 25 to 30 minute boat ride connects Stone Town and Changu Island: The crossing is part of the experience, not just transport.
• The prison dates to 1893: General, or Sir William Lloyd Mathews, built it to house Zanzibar criminals.
• You may also see peacocks and antelopes: These animals add interest beyond the tortoise sanctuary.
• Swimming is possible, but conditions are not ideal: Boat traffic can make the small beach feel crowded.
• The private format suits flexible groups: Only your party joins the tour, with a private guide and transport.

The Short Boat Ride from Stone Town

Prison Island, also called Changu Island, lies about 16 kilometers from Zanzibar’s Stone Town. You reach it by wooden motorized boat, with the crossing taking roughly 25 to 30 minutes.

That short ride gives the half-day outing a clear sense of place. You leave the old town behind and cross open water toward a small island with a very different feel. The trip is not an all-day cruise, and that matters if you are fitting it between other Zanzibar plans.

Pickup is offered, and private transportation is included. The exact pickup arrangement is not specified, so I would confirm the meeting point and departure time when booking. A private tour also means you are not locked into the pace of a large group. If your main interest is the tortoise sanctuary, you can focus there rather than wait for a coachload of people to finish every stop.

The crossing itself may be calm or choppy depending on the weather. Since the activity requires good weather, keep your schedule flexible if possible. A change in conditions can affect the amount of time you spend on the island.

Meeting the Aldabra Giant Tortoises

The tortoise sanctuary is the strongest reason to book this trip. Aldabra giant tortoises were brought to Zanzibar from the Seychelles as a gift to the Sultan of Zanzibar. The supplied details place their arrival around 1915 to 1919, so the exact year is not entirely consistent, but the story connects the animals with Zanzibar’s royal past.

These are not small animals in a tidy display. You will see large, slow-moving tortoises in a sanctuary setting and can take photographs with them. Their size alone makes this the most memorable part of the visit for many people, especially children and anyone interested in wildlife.

I would plan to spend your best attention here. The tortoises are the part of the island that feels distinctive. The prison ruins can be viewed fairly quickly, while the animals give you something to watch and photograph at close range.

Your private guide is useful at this stop. The guide can help you find the tortoises, explain the basic story behind their arrival, and advise you about the best use of your remaining time. No guide names are provided, so you should not expect to request a particular named guide when booking.

The sanctuary is also a good reason to bring patience. The tortoises move slowly, and the appeal is in observing them rather than rushing through for a single photograph. The visit is simple, but it gives the tour its real character.

Seeing the 1893 Prison Ruins

The island’s name comes from a prison built in 1893 by General, also identified as Sir William Lloyd Mathews. It was intended to house criminals from Zanzibar.

The ruins provide historical context, but you should set your expectations correctly. This is not a vast prison complex with many intact rooms or a long museum visit. The remains are limited, and you may spend only a short time looking around them.

That does not make the stop pointless. The ruins help explain why Changu Island is known as Prison Island, and they give the boat trip a second purpose beyond wildlife and swimming. I would treat the prison as a compact historical stop rather than the central attraction.

A guide can add value here by explaining what the buildings were meant to do and how the island fitted into Zanzibar’s past. Because the tour is private, you can ask questions and move on when you have seen enough. If you are mainly interested in architecture or detailed colonial history, though, this visit may feel thin.

The name can also create an expectation of a dramatic fortress. The reality is quieter and more limited. The island is best understood as a short combination of tortoises, ruins, animals, and sea time.

Peacocks, Antelopes, and the Rest of the Island

The tortoises are the headline animals, but they are not the only wildlife you may see. Peacocks and antelopes are also found on the island.

These sightings are an added bonus rather than a guaranteed wildlife tour. You should not book this experience expecting a long animal-spotting expedition. The island visit is short, and the focus remains on the tortoise sanctuary.

Still, the extra species make the stop more varied. After seeing the tortoises and ruins, you have another reason to look around instead of treating the island as a single-photo stop. The animals also make the outing appealing to families.

The supplied information does not give a walking route or a guaranteed number of animal encounters. Your guide can point out what is present during your visit, but conditions will vary. Keep your expectations modest and enjoy any peacocks or antelopes you happen to see.

Swimming at the Small Beach

You can swim in the clear water from the beach at Prison Island. This gives the tour a welcome change of pace after the historical and wildlife stops.

The beach, however, should not be confused with a full beach day. It is a small area, and several boats may gather there. Boat traffic can make swimming difficult, especially at busy times. The setting may look inviting, but you should not assume you will have an empty stretch of sand or an ideal place for a long swim.

Snorkeling is also not presented as a core part of the tour. The guide may be able to advise you about where to swim or snorkel, but the experience does not promise a dedicated snorkeling session or equipment. If swimming is important to you, ask the guide about the safest and least crowded area once you arrive.

Weather can also change the beach stop. One reported outing was shortened to about 1.5 hours because conditions deteriorated. Since this is a weather-dependent activity, clouds, wind, or rain may affect your time in the water and on the island.

I would bring swimwear only if you are comfortable treating swimming as an optional extra. The tortoises and island history should be your main reasons for booking. That way, a crowded beach or rough weather will not ruin the whole outing.

What the Private Format Really Gives You

This is a private activity, so only your group participates. That can be valuable if you want a simpler pace, are traveling with family, or prefer not to spend time waiting for strangers.

The private format does not turn Prison Island into a private beach. Other boats and visitors can still be present once you arrive. The benefit is control over your own group’s timing, not exclusive access to the island.

Your package includes private transportation, a private guide, bottled water, and all fees and taxes. Pickup is offered. Personal expenses are not included, so budget separately for anything outside those listed inclusions.

A private guide can also help you decide how long to spend at each part. You may want more time with the tortoises, a quick look at the ruins, or a short swim before returning to Stone Town. The available information does not promise a fixed order beyond the island visit, so ask about the plan at the start.

The stated duration is about two to three hours, with roughly two hours allocated to the island visit. That makes this an easy add-on to a Stone Town stay. It is not the right choice if you want a full-day island escape.

Is $84 Per Person Fair Value?

At $84 per person, the price is not low for a short outing. You are paying for a private experience rather than a basic public boat transfer, and the package includes transportation, a private guide, bottled water, taxes, and pickup.

The value depends on your group. For a small party, the private format may feel expensive because the actual island program is compact. For a larger group, group discounts may improve the calculation, though the available details do not state the discount amount.

I would consider the price reasonable if you place high value on a private guide and simple transport from Stone Town. The tortoises are a distinctive sight, and you avoid arranging several pieces yourself. I would be less convinced if your main goal is a long beach session, snorkeling, or a full historical tour.

The short duration is the key issue. In good conditions, you can see the main sights and perhaps swim within two to three hours. If bad weather reduces the visit, the cost per hour rises quickly. The operator’s policy provides a different date or full refund if the experience is canceled because of poor weather, but a tour that goes ahead and is shortened by changing conditions may still feel poor value.

This is why I would book it for the tortoises first and treat the beach as a bonus. That mindset gives you a clearer idea of what you are buying.

Who Will Enjoy This Island Visit?

I would recommend the tour to you if you want a short trip from Stone Town with three distinct elements: wildlife, history, and a boat ride. Families may like the large tortoises and peacocks, while couples and small groups may appreciate the private pace.

It also suits anyone with limited time in Zanzibar. The island is only about 16 kilometers from Stone Town, and the boat ride takes around half an hour each way. You can see something beyond the old town without giving up an entire day.

You may want to choose a different activity if you are seeking a quiet beach, serious snorkeling, or a major historical site. The beach can be crowded with boats, and the prison remains are modest. The tour works best when you see it as a compact island visit rather than a full beach excursion.

People who dislike weather-dependent plans should also take care. The cancellation policy allows a full refund when the operator cancels because of poor weather, but conditions can still affect an outing that proceeds.

Practical Booking Advice for Changu Island

The experience is booked, on average, about 71 days in advance. That suggests you should reserve ahead if the private format matters to you, especially during a busy Zanzibar visit.

Confirmation is provided at the time of booking. Free cancellation is available up to 24 hours before the start time for a full refund. Cancellations or changes made within 24 hours are not refunded or accepted.

Most people can participate, and the activity is private. The supplied information does not give detailed accessibility guidance, so ask directly if you have mobility concerns involving the boat, beach, or island paths.

I would also confirm these points before departure:

• The exact pickup location in Stone Town
• The expected boat departure time
• How much time is planned for swimming
• Whether the guide expects you to bring swimwear and personal items
• What happens if weather changes after the boat leaves

These questions are especially useful because the tour can be shorter than expected when conditions turn poor.

Should You Book the Prison Island Tour?

Book it if you want close-up views of Aldabra giant tortoises, a short boat ride from Stone Town, and a private guide who can keep the visit flexible. The animals are the clear highlight, and the combination of tortoises, ruins, peacocks, antelopes, and sea time gives you a pleasant half-day outing.

Skip it if your main goal is a spacious beach or a serious snorkeling session. The beach is small, boats may crowd the swimming area, and the prison ruins do not take long to see.

My practical verdict: this is a worthwhile wildlife-and-history trip when you judge it by the tortoises and private transport. At $84 per person, it is a selective buy, not an automatic bargain. Book it with realistic expectations, and ask your guide to help you find the best available place for a swim.
