Changuu Island

Changuu Island, also known as Prison Island, lies 30 minutes by boat from Stone Town off the west coast of Zanzibar and offers a fascinating blend of history and nature. Originally used in the 19th century for the confinement of slaves and later as a quarantine station during the yellow fever epidemic, the island still houses the 1893-built prison that gave it its name. Today, visitors are drawn to its giant Aldabra tortoises, which can be observed and fed, as well as its clear waters perfect for swimming, sunbathing, and snorkelling. The island also shelters the elusive duiker, a rare small antelope species, adding to its unique wildlife appeal. Combining cultural heritage with natural beauty, Prison Island is a must-visit destination for those exploring Zanzibar.
