A visit to Stone Town brings you to the captivating Prison Island, a tranquil retreat filled with history and natural charm. The island is home to Aldabra tortoises, introduced from the Seychelles in 1919, and they roam freely across the land. Just about half an hour from Stone Town, it’s an ideal spot for snorkeling in crystal-clear waters and enjoying the peaceful shores for sunbathing.

Prison Island has a unique historical background. Initially serving as a quarantine station, it later saw the British build a prison for Stone Town in the 1890s, although the prison was never used. Today, visitors can explore the remnants of the prison structure while enjoying the lush, picturesque surroundings that make this island a favorite among both history enthusiasts and nature lovers.
