Surrounded by perfect blue waters, tiny Prison Island is very scenic. Its proximity to Stone Town on Unguja makes it a popular day trip option. ‘Changuu’ – as it is sometimes called – has had numerous uses throughout history, with the island once used as a slave port and quarantine station, amongst other things.
Nowadays, the island is coated in trees, and a giant tortoise sanctuary can be found at one end. The remains of the prison, which never actually hosted any prisoners, can be found scattered about here and there.
With a stunning beach on offer, fantastic snorkeling just offshore, and marvelous views to boot, Prison Island is well worth visiting when in Stone Town. The boat trip there and back is equally entertaining as you skim across the waves to the secluded island.
