Following its designation as a nature reserve in 1957, this diminutive island represents one of the longest-running island restoration projects in the world and an ecological success story. Habitat restoration, eradication and reintroduction have all led to the resurgence of reptiles, birds and plants on this uninhabited island, including the recovery of the Round Island Boa from the brink of extinction. Access is not permitted unless for scientific research purposes, but the rough seas and rocky shoreline mean this rotund rock is best appreciated from a distance.
This mountainous island is the most remote and inaccessible of the five northern islands of Mauritius. Despite its name, there are no snakes on the island, but it is home to a large colony of seabirds. The water around the island is a popular spot with divers, with excellent visibility. A wall that drops to a depth of 50m creates ideal conditions for observing colourful batfish; elsewhere, reef sharks are regular visitors to a place known as Shark Arena. Access to the island is not permitted, but the surrounding waters offer plenty to enthral visitors.
