History & Wildlife
The Giant Tortoises
Prison Island is famous for its population of Giant Aldabra tortoises, some of which are over 150 years old. These gentle giants were originally a gift from the British Governor of Seychelles in the late 19th century. You can walk among them, feed them, and learn about the conservation efforts to protect this rare species.
A Layered History
The island's history is intriguing. Initially used by Arab slave merchants, the British later built a prison complex in 1890. Though never used for its original purpose, the buildings served as a quarantine station for East Africa during cholera and yellow fever outbreaks. You can still explore these well-preserved ruins today.
Marine Beauty
Changuu Island is fringed by a lovely white sand beach and a small coral reef, making it ideal for a spot of snorkeling and sunbathing. The turquoise waters are calm and clear, providing excellent visibility for witnessing the colorful marine life of the Zanzibar Channel.
