Prison Island, also known as Changuu Island is one of the most popular destinations for day trips from stone Town. Just a short boat ride away, the island offers excellent snorkeling, a nature trail, small beach and the unusual attraction of a sanctuary for giant tortoises. Despite its name, the closet the island has come to actually being used as a prison was by its first owner, a wealthy Arab who sent unruly slaves there for discipline. In 2006, many of the islands old building were restored, and Changuu Private Island paradise was opened, offering 15 deluxe cottages all on the seafront, affording maximum seclusion and privacy. There are also 12 standard rooms in the old quarantine area, with fantastic views back across to Stone Town. If swimming and snorkeling in the crystal blue waters gets too much, have a paddle in the freshwater swimming pool, or hit the ball around on the flood it tennis court. Mathews’ restaurant offers excellent seafood lunches, and 4 course dinners, all overlooking the restored prison ruins.
