Introduction: What to Expect from the Half Day Private Prison Island Tour
If you’re looking to combine history, wildlife, and a bit of relaxation during your stay in Zanzibar, the Half Day Private Prison Island Tour might catch your eye. This guided excursion offers a chance to visit Changuu Island, just a 25-30 minute boat ride from Stone Town, with a focus on exploring the island’s infamous prison ruins and its famous giant tortoise sanctuary.
What we like most about this tour is the personalized experience that a private guide provides, making it easier to understand each site and take your time. Plus, the opportunity to see Aldabra giant tortoises—some over 100 years old—is a major highlight. It’s also quite appealing that the tour includes transportation, all fees, and bottled water, offering good value at $84 per person.
One thing to keep in mind is that this is not a full-day adventure or a snorkeling trip—if you’re expecting pristine beaches or underwater sights, that might not be what you find here. Instead, this tour is best suited for history buffs, animal lovers, or anyone wanting a relaxed but informative visit that combines wildlife with the island’s past.

Visiting Prison Island: A Detailed Look

Getting There: The Journey to Changuu Island
The tour begins with a shared or private boat ride from Zanzibar’s Stone Town, typically lasting about 25-30 minutes. The wooden motorized boat adds a rustic charm, but it’s worth noting that many boats congregate near the small beach on the island, which can make swimming somewhat challenging due to the number of boats and travelers.
The Prison Ruins: A Glimpse into Zanzibar’s Past
Your first stop on the island is the ruins of the old prison, built by Sir William Lloyd Mathew in 1893. These ruins are the main historical feature, giving a sense of Zanzibar’s colonial past and its once-prisoner management system. While some visitors find the remains underwhelming—”not really a beach to go enjoy the day or snorkel,” as one reviewer put it—others appreciate the chance to step into an old structure and imagine the lives once lived there.
What makes this site compelling is its historical context. Though the prison itself isn’t grand or restored, the story behind its construction offers insight into Zanzibar’s colonial history and its once-controversial penal system.
The Giant Tortoise Sanctuary: The True Highlight
Most visitors agree that the true crowd-pleaser here is the Aldabra giant tortoise sanctuary. These tortoises, brought here in 1919 from Seychelles, are quite the spectacle—some are over 100 years old. You’ll get a chance to observe them closely, take photos, and perhaps even touch these gentle giants.
One reviewer described this part as the “coolest” aspect of the trip. It’s a moment that makes the visit memorable, especially for animal lovers or families. The tortoises are well cared for, and the setting allows for fun, relaxed interaction.
Wildlife and Other Species
Beyond the tortoises, the island is home to peacocks and antelopes, adding a touch of nature’s variety to your visit. While not necessarily part of a dedicated safari, seeing these species adds an extra layer of authenticity and enchantment for nature enthusiasts.
Beach Time and Swimming
If you’re craving a swim, the crystal-clear waters at the island’s beach provide a tempting opportunity. However, a review notes that the small beach area is crowded, with many boats around, making it difficult to enjoy swimming or sunbathing peacefully. Still, the water quality is good, and a quick dip can be refreshing after the sightseeing.
Timing and Duration
This tour generally lasts 2 to 3 hours, making it perfect for a morning or afternoon activity. The itinerary is flexible, but weather can influence the experience significantly—as one reviewer shared, poor weather shortened their visit and affected the overall value.
Transport and Guide
The inclusion of private transportation and a personal guide makes for a smooth experience. Your guide helps interpret the sites, answers questions, and enhances your understanding of both history and wildlife. It’s a rare plus for such a short excursion, especially given that group discounts are available if you’re traveling with friends or family.
What Do the Reviews Say?

Feedback from previous travelers offers a balanced view. Many appreciated the value for money, especially considering the private guide and all fees included—”good value for the price,” one reviewer noted.
However, some found that expectations didn’t match reality. For example, a visitor remarked, “What you see in the picture is a little misleading”, highlighting that the beach isn’t ideal for relaxing or snorkeling. This suggests that if your goal is a beach or water-based activity, this tour might not fully satisfy that desire.
Another review expressed disappointment due to weather conditions—the trip was cut short, and they felt they didn’t get full value for the cost. This underscores the importance of good weather for maximizing your experience on Prison Island.
Analyzing the Cost and Value
At $84 per person, this tour doesn’t break the bank, especially with the private guide and transportation included. For roughly 2-3 hours of activity, this is a reasonable price, particularly if you love history and wildlife.
While it’s not a snorkeling or full-day adventure, the price reflects the convenience and focus—you get an intimate look at the island’s past and its famous tortoises without the extra frills. Some travelers might find it excellent value, especially if they’re content with a historical and animal-focused outing rather than beaches or diving.
Who Is This Tour Best For?

This experience suits history buffs, animal lovers, and families looking for a relaxed, educational outing. If you’re seeking an authentic glimpse of Zanzibar’s colonial past paired with a chance to interact with giant tortoises, this tour hits the mark.
It’s less ideal for those wanting beach lounging, snorkeling, or extensive water activities. The crowded small beach area and the focus on site visits mean it’s more about exploration than relaxation.
Final Thoughts: Is It Worth It?

For travelers who appreciate learning about local history and animal encounters, this tour offers particularly good value. The private guiding ensures a personalized experience that can be tailored to interests, whether that’s photographing tortoises or exploring the prison ruins in detail.
But remember, the overall experience depends heavily on weather and expectations. If you’re realistic about what the island offers—a quick historical visit with some wildlife—you’re likely to find it worthwhile.
To sum it up, this tour balances history, wildlife, and a bit of Caribbean charm in a way that appeals to curious travelers looking for a half-day adventure. It’s best suited for those seeking an authentic, family-friendly outing rather than a beach-centric day.
