♡ Save
Join a free tour to Prison Island from Stone Town! Discover historic prison ruins, encounter giant Aldabra tortoises, and enjoy a short scenic boat ride while exploring this unique island’s charm.
Escape to Prison Island, locally known as Changuu Island, a fascinating destination just 20–30 minutes by boat from Stone Town. This small island carries a unique blend of history, nature, and relaxation, making it one of Zanzibar’s most popular excursions. Originally planned as a prison in the late 19th century, the site was later used as a quarantine station, and today the preserved ruins still stand as reminders of its past.
The highlight of your visit is meeting the giant Aldabra tortoises, some over 150 years old, roaming freely in the sanctuary. You’ll have the chance to walk among them, feed them, and capture memorable photos. The island also offers beautiful beaches and crystal-clear waters, perfect for swimming and sunbathing. Surrounded by calm turquoise seas and scenic views of Stone Town in the distance, Prison Island is a perfect half-day trip that combines history, wildlife, and relaxation.
Whether you’re drawn by its cultural heritage or natural beauty, a visit here promises an unforgettable Zanzibar experience.
