Prison Island gets its name from the prison built to condemn Zanzibari citizens to the isolation of the Island looking out at the coast. Previously owned by Arab to house his rebellious slaves, the prison was never used and the Island is now home to a tortoise sanctuary and prison ruins. Prison Island is 20 minutes away from stone town by boat and has spectacular coral reef to enjoy while snorkeling, giant tortoises shuffle through the trees with the patience that old age brings you. Originally thought to be from the Comoros Islands and Seychelles some of these tortoises are said to be over 100 years old. Stately and lumbering the tortoises have been known to take children on a ride.

Lunch is available on the island and then you are left to your own devices, if you are feeling active you can explore on the hiking trails, snorkel in the crystal clear waters in search of colorful tropical fish darting through the reef or soak up some sun on the power white beach. The prison Island is a great companion to a morning city tour. After an eventful morning of walking through the busy streets of Zanzibar, you can enjoy this slow and relaxing island excursion.
