Wildlife
History
Prison Island served as a quarantine station and, earlier in the 1860s, as a holding site tied to regional slave trade and coral-mining operations—structures on the island reflect those functions.
Conservation
The tortoise sanctuary is maintained to protect aging Aldabra tortoises and relies on visitor fees and regulated feeding; visitors should avoid disturbing nesting or reef life and use reef-safe products.
