Prison Island zanzibar, this island is off the coast of Stone Town and is also known as Changuu island (don’t mix it up with Canggu in Bali!).  Although Prison Island in Zanzibar seems like an intimidating name (and like it might not be a fun day trip!), it’s a bit of a misnomer. There never actually was a prison on the island. They used the island to house rebellious slaves in the 1860s and as a place to quarantine people with yellow fever.

Nowadays, the island is a tourist destination because it is home to giant tortoises. It’s a peaceful sanctuary for this vulnerable species. Some people estimate that some of the tortoises on the island are more than 150 years old!
