Aldabra is a remarkable and pristine tropical coral atoll. Not only is it the second-largest coral atoll in the world, but it is also famous for having the largest population of giant tortoises. It is part of the Seychelles in the Indian Ocean around 700 southwest of the country's main island, Mahé Island.

On the atoll, there are paved walking trails from the entry point of La Gigi to see the large lagoon and the slowly lumbering residents of the atoll. But getting to the atoll is much easier said than done. Seychelles is a fascinating country to visit, it is possible to visit on a budget although it is generally very expensive and it is not possible to get to Aldabra on a budget.


What To Know Of Aldabra and The Giant Aldabra Tortoises

During the 18th century, there were expeditions to capture the Aldabra giant tortoises. But the island remained uninhabited due to the lack of fresh water on the atoll and which also led to later colonizing efforts failing. Unfortunately, the tortoises were extensively hunted and in 1842 just two ships were reported to have taken 1200 of the giant creatures.

By 1900 they were nearly extinct but fortunately today they are protected, and their populations have recovered. Today there are around 100,000 giant tortoises on Aldabra.

These stunning and slow-moving tortoises vary in size around the atoll but normally reach a length of 105 centimeters (41 in) and weigh up to 350 kilograms (770 lb).

The tortoises are gentle giants feeding on plants, trees, and the algae growing in the freshwater pools on the island. At famous Aldabra giant tortoise was called Adwaita, and he lived to be around 250 years old (he died in India's Alipore Zoological Gardens in 2006).

Visiting The Giant Tortoises of Aldabra

Aldabra is extremely remote and is very protected as it is a very fragile atoll. Tourism is strictly controlled and visitors need to get prior permission from Seychelles Islands Foundation (SIF). Access is limited to specific areas of Aldabra and all visitors must be accompanied by a SIF staff member at all times.

  • Permission: All Visitors Must Have Prior Permission From SIF

Once one has gotten permission, there are cruises operated by several companies together with dive boats - but don't expect it to be cheap! An indication of the challenges of getting to the islands can be seen that in 2012 there was only an annual average of 900 tourists visiting the atoll.

Besides seeing the Giant Tortoises, another of the attractions on the atoll is drift-diving. Jump into the atoll's lagoon and be greeted with up-close encounters with doctor fish, snappers, and mantas, as well as black-tip sharks, dolphins, and manatees.
