A short wooden skiff cuts through the warm Indian Ocean as Stone Town recedes to a line of coral roofs. In 20 minutes the boat sets anchor off Changuu — commonly called Prison Island — where white sand and a low, weathered pier frame a compact wildlife refuge. Giant tortoises move like living boulders across scrubby lawn; peacocks fan iridescent tails above coral-strewn shallows.

A short wooden skiff cuts through the warm Indian Ocean as Stone Town recedes to a line of coral roofs. In 20 minutes the boat sets anchor off Changuu — commonly called Prison Island — where white sand and a low, weathered pier frame a compact wildlife refuge. Giant tortoises move like living boulders across scrubby lawn; peacocks fan iridescent tails above coral-strewn shallows.
The island’s layered history is tangible: a 19th-century quarantine and later a brief prison project left masonry buildings that now stand bright against the sea. Geologically this is a coral islet, rimmed with fringing reefs that shelter small fish and provide easy snorkel access. Culturally, visits link directly to Zanzibar’s coastal trade past — the island was a strategic holding place for people and goods moving through the archipelago.
Expect an hour on the island to split between the tortoise sanctuary, a walk by the historic compound, and optional snorkeling over shallow coral gardens. The water is warm year-round; currents near the reef can shift and visibility varies after rain.
Plan practicalities: bring reef-safe sunscreen and a towel, wear water shoes for rocky steps, and carry cash for small local fees or tips. If you snorkel, basic swimming ability is required — staff provide masks and fins. Morning departures avoid midday sun and often deliver clearer water.
This is an accessible half-day outing that mixes wildlife viewing, a compact dose of history, and light marine exploration — good for families and travelers seeking an uncomplicated, coastal experience off Stone Town.

Yes—families are common. Infants must sit on laps on the boat; parents should supervise around water and wildlife.
Built in the late 19th century as a quarantine and later repurposed as a prison, Changuu’s masonry buildings now host a small sanctuary and tourism facilities.
The tortoise sanctuary depends on visitor fees and responsible behavior; use reef-safe products, avoid touching coral, and follow sanctuary rules to minimize impact.
