A low-lying Indian Ocean island north of Mauritius, shaped by quarantine heritage and rich island ecology.
Île Plate
Île Plate, widely known in English as Flat Island, is a small uninhabited island in the Indian Ocean lying about 11 kilometres north of the northern tip of Mauritius. The island forms part of the Rivière du Rempart District in the Republic of Mauritius and is surrounded by smaller islets, including Îlot Gabriel and Pigeon Rock, the latter belonging to the Islets National Park. Together these sites are recognised as national protected areas, giving Île Plate an identity that bridges ecological protection and cultural heritage.
The island is notable for being very low-lying, with only a modest bluff rising near its interior, which has raised concerns about its long-term vulnerability to sea-level rise. Its landscapes combine limestone beaches, reddish and dark volcanic rocks, patches of wetland, and a surprisingly diverse interior vegetation that includes both indigenous and introduced plant species. Beyond its physical setting, Île Plate carries a heavy historical layer as a former quarantine station used from the mid-19th century to the 1930s, when it housed incoming indentured labourers and other immigrants during epidemic outbreaks.
The island is also recognised for its biodiversity value. It supports nesting seabirds, endemic and reintroduced plant species, and a remnant population of the critically endangered Bojer's skink, once decimated after the arrival of invasive mammals. A small military presence remains on the otherwise uninhabited island, and visitors typically reach it by chartered yacht or catamaran, with snorkelling and diving at nearby Pigeon Rock adding to its appeal.
