Prison Island Tour Zanzibar (Changuu Island Half-Day Experience)
The Prison Island Tour in Zanzibar is one of the most rewarding half-day excursions you can take from Stone Town. Just a short boat ride away, Prison Island combines history, wildlife, crystal-clear waters, and relaxed island vibes—making it a must-do for first-time visitors and repeat travelers alike.
We have designed this experience to be smooth, informative, and memorable, guided by locals who know the island inside out.
What Is the Prison Island Tour in Zanzibar?
The Prison Island Tour is a 3–4 hour guided boat excursion from Stone Town to Changuu Island, where visitors meet giant Aldabra tortoises, explore historic prison ruins, and enjoy swimming or snorkeling in the Indian Ocean.
Despite the name, Prison Island is not gloomy or intimidating.
Instead, it’s a peaceful island rich in stories, nature, and photo-worthy scenery.
Where Is Prison Island Located?
Prison Island (also called Changuu Island) lies approximately 5.6 km off the coast of Stone Town.
The journey takes about 25–30 minutes by traditional wooden boat, offering beautiful views of Zanzibar’s coastline and turquoise waters.
What Makes Prison Island Famous?
Prison Island is famous for four main reasons:
Giant Aldabra Tortoises Sanctuary
The island is home to Aldabra giant tortoises, some of which are over 100 years old.
Originally gifted to Zanzibar in the late 19th century, these gentle giants are now protected and carefully monitored.
You’ll be able to:
Learn each tortoise’s age and story
Take close-up photos
Feed them under guide supervision
Historic Prison & Quarantine Ruins
Although built to house rebellious slaves, the prison was never actually used for inmates.
Instead, the island later served as a quarantine station for yellow fever cases.
Walking through the ruins offers a rare glimpse into Zanzibar’s colonial past.
Clear Waters & Marine Life
The shallow waters around the island are ideal for:
Swimming
Light snorkeling
Cooling off after the tour
Relaxed Island Atmosphere
Prison Island is quiet, uncrowded, and calm—perfect for slowing down and enjoying nature just minutes from the city.
How Long Does the Prison Island Tour Take?
The Prison Island Tour takes approximately 3 to 4 hours, including boat transfers, guided exploration, and optional swimming time.
This makes it ideal for:
Cruise passengers
Short-stay visitors
Travelers combining it with a Stone Town walking tour

Die deutschsprachige Guide war klasse. Es war ein echtes Erlebnis, auch für meine Frau, die nur schlecht Englisch versteht. Das Mittagessen und der Nachtisch mit frischen Früchten war sehr schmackhaft. Die deutschsprachige Tour durch Stone Town war ebenfalls gut, aber insgesamt nicht so toll wie die Spice Farm.Posted on Tripadvisor DTDOctober 28, 2025Verified Outstanding experience with Blue Green Safari Zanzibar! We had an amazing experience with Blue Green Safari. From start to finish, the team was highly professional, punctual, and incredibly accommodating.

They even helped us arrange donations for a local school and village, which meant a lot to us and made the trip feel even more meaningful.
