What to expect on a Prison island tour

A "prison safari" in Zanzibar likely refers to a tour of Prison Island (Changuu Island), which involves a boat ride from Stone Town to see the giant Aldabra tortoises and explore the island's history.
What to expect on the tour
Boat ride: A local motorboat or traditional dhow will take you from Stone Town to the island, a trip that typically takes about 30-45 minutes.
Giant tortoises: You will have the opportunity to see and learn about the Aldabra giant tortoises that live on the island. Some are over 150 years old. You may be able to feed them for an extra charge.
Historical exploration: Take a guided tour to learn about the island's history as a former prison and quarantine station.
Beaches and water activities: Enjoy the white sandy beaches, sunbathe, swim, and snorkel in the clear waters around the island to see colorful fish and coral.
