How to Visit Prison Island Responsibly

Visiting Prison Island (also known as Changuu Island) is one of the most appealing day-trips you can take from Stone Town, Zanzibar. However, if you really want to get the most out of the experience — while also protecting the island, its wildlife, and its heritage — it’s wise to go in with awareness and respect. In this guide you’ll learn not only how to see the island, but how to visit responsibly so that your visit becomes positive both for you and for the local environment and community.

Why Visit Prison Island?

First of all, Prison Island is steeped in fascinating history. Though its name suggests a prison, in fact it was never used as such for long; instead it functioned as a quarantine station and later a retreat. GoSmart Zanzibar Tours and Safari+1 Moreover, the island hosts giant Aldabra tortoises — some over 100 years old — living in a sanctuary that attracts many visitors. WeAreZanzibar+1 Additionally the surrounding coral reefs and tranquil beaches make it a beautiful spot for snorkeling, relaxing, andexploring. Tour Travel World+1 But as good as all of that sounds, you’ll get more from your trip—and cause less harm—if you plan ahead and act responsibly.

1. Choose the Right Time & Cruise

Planning your departure is step one. Because the island is just a short boat ride (about 30 minutes) from Stone Town, you’ll want to leave early to avoid crowds and the midday heat. GoSmart Zanzibar Tours and Safari+1 Early mornings usually mean cooler air, calmer seas and better light for photography. In addition, going off-peak (outside the busiest tourist months) helps ease pressure on the island’s facilities and natural environment. Frequently, visitors arrive en masse and the outcome is long lines, more impact on the ecosystem, and a less personal experience.

When booking your boat, make sure it is licensed and adheres to safety standards. Ask whether the operator contributes part of the fee to local conservation or clean-up efforts; a socially responsible operator will be open about this. Also check the departure point and ensure the boat does not overload, so that marine life and coral reefs are disturbed as little as possible.

2. Respect the Wildlife – Tortoises & Marine Life

Arguably the star attraction of Prison Island is the giant Aldabra tortoises residing there. These gentle creatures are remarkable—not only for their size and age, but as living reminders of conservation efforts in Zanzibar. WeAreZanzibar+1 When interacting with them, follow these rules:

Do not attempt to touch or climb on the tortoise shells. Even though it looks harmless, this can stress them and damage their spine.
Stay on marked paths and within the enclosures where visitation is allowed.
Avoid feeding them human food—tourist feeding can upset their diet and health.

Similarly, the coral reef around the island needs protection. So always wear reef-safe sunscreen (avoid chemicals like oxybenzone & octinoxate) and never stand on or touch live coral. Jess Eats The World+1 Wild marine life should be observed but not harassed. If snorkeling, make sure your guide is aware of conservation practices.

3. Dress & Pack Thoughtfully

What you wear and bring matters—not only for your comfort, but for your impact and cultural respect. For instance:

Bring lightweight, breathable clothing because the island can get hot, especially around midday.
Wear a hat, sunglasses and high-SPF sunscreen. A reusable water bottle is wise, too. WeAreZanzibar+1
Bring swimwear for beach time or snorkeling, but if you leave the beach area and venture into villages or historic buildings, dress more modestly: cover shoulders and knees, out of respect for the predominantly Muslim culture in Zanzibar. Jess Eats The World+1
Pack trash bags or use the one provided so you don’t leave plastic or other waste behind. Minimising single-use plastics is particularly important in Zanzibar. Mandari Travel+1

4. Support the Local Community & Economy

You can make a more positive contribution by supporting locally-owned businesses, and being mindful of where and how you spend. For example:

Buy snacks, drinks or souvenirs from island vendors rather than relying purely on the tour operator’s onboard service. This channels money into local hands.
If you hire a guide, choose one from the island or Stone Town who knows the local environment and history—this creates employment and improves visitor experience.
Ask your tour operator how much of your fee goes towards conservation or community programmes—responsible operators will have transparent answers.
Travellers who consider these aspects help tourism become a genuine benefit to Zanzibar, not just an invisible extraction. Tours Zanzibar+1

5. Preserve the Environment

Because Prison Island and surrounding waters are ecologically sensitive, you should actively minimise your footprint. Here’s how:

Stay on designated trails: venturing off path may erode soil, destroy vegetation and disturb nesting sites.
Avoid single-use plastics: use a refillable bottle, refuse plastic bags and straws. Zanzibar has banned many single-use plastics. Jess Eats The World+1
Do not collect coral, shells or marine life. What looks like a souvenir can harm the ecosystem.
Participate in or support beach/reef clean-ups if offered. Some operators or local groups conduct short sessions which make a real difference. Tours Zanzibar+1
By adopting even a few of these practices, you’ll help ensure that the place remains beautiful for future visitors—and for the local community who depend on it.

6. Choose a Responsible Tour Operator

Not all tours are created equal. If you want a meaningful, sustainable experience, pick a provider that is aligned with your values. Ask questions such as:

Are the boat and island operators licensed and following marine conservation rules?
Does the tour limit group size to avoid overcrowding?
Do fees contribute to the care of tortoises, coral reefs and island maintenance?
Are guides trained in environmental awareness and local culture?
For example, many snorkelling and tortoise-interaction tours on Zanzibar have been flagged for being overly touristy and even unethical. One reviewer wrote:

“While visiting Pregison Island … don’t sit on the tortoises or feed them human food.” GVIA Australia+1
Choosing the right operator makes all the difference—your visit becomes a respectful adventure rather than a damaging one.

7. The History & Story of Prison Island

Understanding the story behind the island enriches your visit. The island’s official name is Changuu, but it became widely known as “Prison Island” although the original prison plan was rarely used. Wikipedia+1 Initially, the island served as a coral rag mining site and later as a quarantine station for yellow fever under British-Zanzibari administration. GoSmart Zanzibar Tours and Safari+1
Walking among the ruins, you’ll see thick coral-stone walls and old colonial architecture. These serve as tangible reminders of Zanzibar’s colonial era, its involvement in the slave trade, and the transformations the island has gone through. On your visit, you might reflect on how history, nature and tourism intersect in this small but significant place.

8. What to Do & What to Avoid

What to Do:

Arrive early to beat crowds and enjoy peace.
Hire a local guide for in-depth storytelling and context. WeAreZanzibar
Snorkel in the shallow reef carefully, view the giant tortoises respectfully, take photos of the scenic shoreline and historic ruins.
Use reef-safe sunscreen and wear water shoes if exploring rocky parts.
Visit the tortoise sanctuary and learn about conservation.

What to Avoid:

Avoid climbing on tortoise shells or riding them—even if a guide or local invites you. This may be harmful to the animal. Jess Eats The World+1
Avoid touching coral or stepping on it. Each fragment is a living organism.
Avoid leaving any litter, even a tiny wrapper—it may degrade into microplastics.
Avoid loud behaviour or ignoring local customs—respect the environment and the people who live here.

9. Practical Tips Before You Go

Bring cash, because the island has limited card facilities. Tour Travel World
Wear comfortable walking shoes, especially if you plan to explore the old buildings and forested parts.
Hydrate well and protect yourself from the sun: bring reusable bottle, hat, sunglasses and sunscreen.
Speed-boat rides can cause motion sickness—if prone, take appropriate medication.
Check tide times and sea conditions. Although the reef is near the beach, strong currents may alter safe swimming times.
Leave early and plan your return boat in advance, since the last boats may be less frequent.
Choose a full-day or half-day option depending on your pace—some visitors combine Prison Island with a Stone Town walking tour or a beach visit.

10. Reflecting on Your Experience

When you leave Prison Island, take a moment to reflect on your experience and the impact you had. Ask yourself: Did I cause any harm or disruption? Did I act with respect? Did I support the local economy or wildlife efforts?
Small actions make a difference. If every visitor took five minutes to think and act consciously, the cumulative result is huge. Ensuring that we visit places like Prison Island responsibly means that the island remains beautiful, wild and meaningful—not just for us, but for the generations ahead.

Visiting Prison Island can be so much more than a photo stop or a brief boat ride. When you go with care, intention and respect, your trip becomes a meaningful connection with nature, history and culture. So next time you step onto that boat from Stone Town, plan ahead, act responsibly, and allow the island to tell its story—while you leave it better than when you arrived.

In Summary

Visiting Prison Island responsibly means:

Choosing the right time and tour operator
Respecting tortoises, coral reefs and local ecosystems
Dressing thoughtfully & packing smartly
Supporting the local economy and choosing eco-friendly practices
Educating yourself on the history and avoiding harmful behaviour
Reflecting on your impact and committing to better travel

By following these steps you’ll enjoy one of Zanzibar’s most iconic visits in a way that honors the place, the animals, and the people who call it home.

Your journey to Prison Island isn’t just about arriving—it’s about leaving with a positive imprint, for you and for the island.

Happy, responsible travelling!
