You step off the skiff onto pale sand and the breakers seem to pull back in surprise, the ocean nudging you ashore as if to make room for the island’s slow residents. Mangroves give way to a short path through open scrub and the low silhouette of the 1893 jail looms—its stone walls more museum than prison now, sun-bleached and patient.

You step off the skiff onto pale sand and the breakers seem to pull back in surprise, the ocean nudging you ashore as if to make room for the island’s slow residents. Mangroves give way to a short path through open scrub and the low silhouette of the 1893 jail looms—its stone walls more museum than prison now, sun-bleached and patient.
Changuu, better known as Prison Island, has a layered past: conceived as a confinement site, repurposed as a yellow fever quarantine, then a colonial gift-stop that received Aldabra giant tortoises in the early 20th century. The island sits on coral limestone typical of Zanzibar’s offshore cays; the reef flats around it sculpt tides and channel currents that make for accessible snorkel zones teeming with surgeonfish, parrotfish and wrasse.
Culture here is city-close: tours run from Stone Town, and the island’s Matthews restaurant carries that straightforward coastal hospitality—fresh seafood, cold juice and a sea view. The tortoise sanctuary operates with conservation in mind; handlers and foundations manage feeding and visitor interactions.
Practical guidance: plan for a three-hour excursion from Stone Town with a short boat transfer. Bring reef-safe sunscreen, swimwear, and a towel; snorkeling is optional but brings the reef to life. Watch your step around tortoises and keep fingers clear of their beaks when feeding. Weather can shift quickly—midday sun is strong, and brief squalls are common in the rainy season—so pack a light wind layer and bottled water. With easy walking, local guides, and a mix of wildlife viewing and snorkeling, Changuu is an efficient half-day escape that blends natural history with hands-on wildlife moments.
