Changuu Island earned its name not from prisoners — none were ever held there — but from a quarantine station built in 1893 to isolate yellow fever cases arriving by dhow.
The British colonial administration purchased the island from an Arab trader who had intended it as a detention facility for recalcitrant slaves, yet by the time construction began, slavery was outlawed and the cells were repurposed for medical quarantine. The coral-rag hospital, its arched corridors open to the Indian Ocean wind, processed thousands of arrivals during the cholera and plague outbreaks that swept East Africa through the 1920s. Today the roofless wards and rusting iron beds remain, a skeletal monument to a public health infrastructure that has long since migrated to the mainland.
The island's transformation began in 1919, when the British governor received four Aldabra giant tortoises as a gift from the Seychelles administration. Their descendants now number over one hundred and fifty, many exceeding a century in age and two hundred kilograms in weight. The tortoises move freely across the island's twelve hectares, congregating in the shade of casuarina groves and along the coral-sand pathways that encircle the quarantine ruins. Their longevity and the island's relative isolation have made Changuu a de facto sanctuary, though it lacks formal conservation designation. Visitors feed them leaves and photograph the deep concentric rings on their carapaces, each ridge marking a year of growth.
Stone Town Prison Island tours typically depart from the dhow harbours north of Forodhani Gardens, with motorised fibreglass boats replacing the sail-powered vessels that once carried quarantine patients. The crossing takes twenty minutes in calm water, passing the limestone battlements of the Old Fort and the cargo wharves of Malindi Port. Arrival is at a concrete jetty on the island's western shore, where the conservation fee is collected and a network of coral-paved trails begins. The quarantine complex occupies the island's centre, its walls pierced by louvred windows designed to maximise airflow during the pre-antibiotic era. Beyond the ruins, snorkelling sites fringe the northern and eastern coasts, where the reef drops sharply and visibility often exceeds fifteen metres. Some Stone Town and Prison Island tour packages combine the island visit with spice-farm stops or Nakupenda sandbar excursions, extending the itinerary to a full day. Independent travellers often pair the morning crossing with an afternoon return, allowing time to explore both the tortoise enclosures and the shallow reef without the congestion that peaks after midday.

A step-by-step walkthrough of Stone Town Prison Island tickets — what you'll see, how long each stage takes, and the details that matter.
You board a fibreglass motorboat at the dhow harbour north of Forodhani Gardens, the Stone Town Prison Island tour departing once the group reaches capacity — typically eight to twelve passengers.
The crossing is direct, the boat cutting east past the Old Fort's crenellated walls and the container cranes of Malindi, the limestone facades of Stone Town receding into a single pale line. Twenty minutes later you step onto the concrete jetty at Changuu, where the conservation officer collects the twenty-two-dollar fee and hands you a laminated map.
The coral-paved path leads inland, splitting at the quarantine ruins. You walk through roofless wards, the iron bed frames still bolted to the floor, louvred shutters hanging at oblique angles. Aldabra tortoises cluster in the shade beside the northern wall, some with carapaces worn smooth by a century of handling. You crouch to offer a hibiscus leaf; the nearest tortoise extends its neck, retracting only when the leaf is consumed. The ranger stationed nearby estimates this individual at one hundred and ninety years old, though no birth records exist.
Beyond the ruins the trail descends to a narrow beach, where you wade into knee-deep water over coral rubble and seagrass. Snorkelling gear is available at the jetty for an additional fee. The reef edge lies thirty metres offshore, marked by a sudden colour shift from turquoise to indigo. You return to the jetty by early afternoon, the boat idling in position for the return crossing.
The attraction is open daily from 09:00–16:15.
No, the 22 USD conservation fee per person is typically paid separately upon arrival at Changuu Island.
