Also known as changuu island, is just off the coast of stone town, zanzibar. Now a tourist attraction, prison island was once a place where slaves were detained and at one point, it also served as a place of quarantine.

The boat ride from stone town takes 20-30 minutes and the seas at times can be a bit rough. Arriving on the island, there is a mysterious rustic wooden bridge that hovers a few meters above the water, jetting out into the sea. Prison island is a refuge for giant sea tortoises, originally a gift from the seychelles.

A 5 minute walk across the island leads to the former prison ruins. Though in their successful days it was a torturous place to be, nowadays the ocean cliffs, the overgrowth of the plants on the stone walls, and the view of the turquoise ocean is gorgeous.
