The dhows fan out from Stone Town and in thirty minutes the silhouette of Prison Island—Changuu—resolves from the horizon: a low coral ring, a white crescent of sand and a grove of wind-riffed casuarinas. The boat slides into a shallow lagoon where the water turns the color of a coin and the island’s most famous residents move with improbable calm. Aldabra giant tortoises lift slow heads and shuffle toward visitors who come to see them up close.

Once used as a 19th-century quarantine station for yellow fever and briefly considered as a prison, Changuu’s history is compact but visible in rusted anchors, stone buildings and the island’s old path network. Geologically the island is a raised coral platform—reef ridges, sandy beach and seagrass beds that shelter small fish and provide accessible snorkel flats. Local life centers on simple hospitality: a small beach restaurant (often called Matthew’s), fishermen in hand-crafted boats and guides who steer visitors between history and reef.
Practical guidance: this is a half-day, easy outing with hotel transfers and a 30-minute boat each way. Morning departures offer calmer seas and clearer water; afternoons can be busier. Snorkeling here is approachable—shallow coral and fish, not a drift dive—so reef shoes and sunscreen matter. There’s a modest fee to feed tortoises on-site; supervise children and keep fingers away from their beaks. Respect wildlife, bring cash for small purchases and time your trip around tides for the best swim conditions. For an urban escape that pairs wildlife, beach and snorkel in a single, accessible package, Prison Island is hard to beat.
The crossing is roughly 25–35 minutes each way on a typical motorboat, depending on sea conditions.
Yes—snorkeling in shallow reefs is common; gear is often provided but bring your own if you prefer a better fit.
No—the Aldabra tortoises were introduced from the Seychelles and have been kept on Changuu Island for over a century.
Yes, but supervise children closely around tortoises and in shallow water; infants typically must sit on laps during transport according to some operators.
