This beautiful island is one of the least explored tour destinations in Seychelles. It has been a nature reserve since its acquisition by the Royal Society for Nature Conservation in 1968; it was declared a Special Reserve by the Seychelles government in 1975 and is managed by BirdLife Seychelles. The island is open to visitors only on certain days and the area is strictly managed. Visitors may hope to see some of the 250,000 birds that come to nest every year, the island is a haven for several rare species including the Seychelles warbler, Seychelles magpie-robin and Seychelles fody.

Seabirds include the brown noddie, lesser noddie, wedge-tailed shearwater, audubon’s shearwater, bridled tern and fairy tern. A visit to Cousin from Praslin can be combined with the nearby island of Curieuses for a BBQ lunch followed by snorkelling at St. Pierre.
