“Tortoises, Turquoise Waters, and a Taste of History”
Just a short boat ride from Stone Town, Prison Island - also known as Changuu Island - is one of Zanzibar’s most popular half-day excursions. This small, scenic island combines history, wildlife, and relaxation, making it a must-visit during your time on the archipelago.


About the Island
Originally used as a quarantine station in the 19th century and once planned as a prison for rebellious slaves (though never actually used for that purpose), Prison Island is now best known for its:
• Giant Aldabra tortoises, some over 150 years old
• Historic prison ruins and quarantine buildings
• Crystal-clear beaches and coral reefs, perfect for swimming and snorkeling
It’s a perfect mix of nature, history, and tropical beauty.

What You’ll Experience
