The Island named after the Prison ruins. The island is around 800m long and 230m wide at its broadest point. The British First Minister of Zanzibar, Lloyd Mathews, purchased the island in 1893 and constructed a prison complex there. No prisoners were ever housed on the island and instead it became a quarantine station for yellow fever cases.
You can snorkel in the crystal clear water and search for colorful tropical fishes and attractive corals. The Island is also home for Peacock and families of Giant Tortoises from Seychelles in the late 19th century. You have not seen so many turtles in one place. There were more than 200 long times ago, but now around 50 left. If you are brave enough it is possible to feed them, touch them and take many pictures.
