Prison Island, also known as Changuu Island, lies just off the coast of Zanzibar and offers a unique historical and wildlife experience. Originally intended as a prison, the island was later used as a quarantine station for yellow fever victims. Today, it is a popular destination for visitors looking to explore its history and wildlife.

The island is home to a sanctuary of giant Aldabra tortoises, some of which are over 100 years old. Visitors can interact with these gentle giants and explore the remains of the historical prison buildings while enjoying the island’s stunning beaches and crystal-clear waters.
