NEED TO KNOW
The atoll is comprised of four large coral islands which enclose a shallow lagoon; the group of islands is itself surrounded by a coral reef.
Due to difficulties of access and the atoll’s isolation, Aldabra has been protected from human influence and thus retains some 152,000 giant tortoises, the world’s largest population of this reptile.
Four idyllic coral islands encircling an enormous shallow lagoon make up this atoll, where humans have, by and large, kept away. Out of the way of shipping lanes and with no fresh water, this UNESCO World Heritage Site is one of the most remote and harsh environments on the planet.
Despite this, the Indian Ocean’s last flightless bird, the Aldabra rail, unlike the doomed dodo, has managed to survive here. Just as content are tens of thousands of turtles, while sharks, barracudas, and countless manta rays bask in the beautifully clear turquoise waters.
