Commonly referred to as Prison Island, Changuu Island is a 30-minute boat ride from Stone Town on the main Zanzibar Island. The island’s unofficial name developed when, in a dark chapter of Zanzibar’s history, slave traders used Changuu Island as a holding space for slaves in transit. Today, the island is a popular relaxation spot for Zanzibar locals and tourists, who come to swim, snorkel and sunbathe. There’s a resort on Prison Island, complete with a swimming pool, sun loungers, and a restaurant, so it has everything you need for a day trip. But what also makes this island special is that it’s now a sanctuary for Aldabra tortoises – one of the largest tortoises in the world, and thought to be one of the longest-lived creatures in the world. It’s estimated that the oldest tortoise on Changuu is 196 years old – now that’s a Zanzibar attraction!

One of the best things to do in Zanzibar is wander the streets of Stone Town. There are many unique places to see in Stone Town, including beautiful boutique shops and plenty of fabulous restaurants. Venture around the Forodhani Gardens and the Old Fort! You can easily walk around Stone Town yourself, but it’s best to book a walking tour with Colors of Zanzibar to learn more about what you see.

Nungwi Mnarani Aquarium is a perfect stop. This lovely natural rehabilitation center focuses on preserving and protecting injured wildlife in the area. It’s especially known for its green sea turtle and hawksbill sea turtle rescue program, and you can meet some of their residents at the Mnarani Marine Turtles Conservation Pond. This pristine grotto is home to several sea turtles, all of whom have been injured or caught in fishermen’s nets. These marvelous creatures use the pool to rest and heal under the watchful eye of the staff members, before eventually being released back into the wild. And you don’t just get to look at the animal. You can swim alongside them!. Hop in the warm waters and meet some new reptilian friends, watching their unique behaviors and interactions.
