The short answer

Quick answer

Prison Island is a short boat outing from Stone Town focused on history and giant tortoises; Nakupenda adds a sandbank and swimming experience. The sandbank’s shape and accessibility depend on tides and sea conditions.

01

What is Prison Island?

Changuu is commonly called Prison Island. Visitors come for its historical buildings, coastal setting and giant tortoises. A guide should explain the island’s layered history rather than reducing the stop to animal photographs.

02

What is Nakupenda?

Nakupenda is a sandbank experience near Stone Town, often combined with swimming, snorkeling and lunch. It is exposed to sun and its usable space changes with the tide, so timing matters.

03

What should be confirmed?

Confirm boat type, life jackets, entrance fees, lunch, shade, snorkeling equipment and hotel transfers. Follow staff instructions around tortoises and do not touch or feed wildlife unless explicitly permitted under supervised rules.
