Prison Island, also known as Changuu Island, is a charming small island 30 minutes by boat from Stone Town. Historically it was planned as a prison for rebellious slaves but was never used as such. Today it's home to Aldabra giant tortoises, some over 150 years old. Enjoy feeding and photographing the tortoises, swimming, and snorkeling in crystal-clear waters.
Island entry $4. Boat rental $20-30 depending on group size. Organized tour all-inclusive $25-40
Morning (8-10am) for cooler temperatures and more active tortoises. Dry season (June-October) offers calmer seas for the boat ride.
