Prison Island & Sandbank Excursions from Stone Town

A visit to Prison Island, also known as Changuu Island, is one of the most enjoyable half-day trips you can take from Stone Town. Despite its name, the island's prison was never actually used to hold prisoners; instead, it became a quarantine station in the early 1900s. Today, the island is best known for its colony of giant Aldabra tortoises, some of which are over a century old. You can feed them and watch them lumber about the conservation sanctuary – a big hit with families. The surrounding waters are a haven for snorkeling, with colourful fish and, at the right time of year, sea turtles gliding serenely by. After exploring, relax on the pristine sandbanks or enjoy a refreshing swim before the short sail back to Stone Town. A private dhow trip combines leisurely sailing, crystal-clear water, and unforgettable wildlife encounters – the perfect escape from the mainland bustle.
