The Egmont Islands are an uninhabited coral atoll group in the Chagos Archipelago of the central Indian Ocean, administered as part of the British Indian Ocean Territory. They form a low-lying ring of islets around a central lagoon.

There are no permanent settlements and the islets are largely natural - sand, vegetation and fringing reef surround a sheltered lagoon. The atoll provides habitat for seabirds and marine life typical of remote Chagos reef systems.

The islands are part of the wider Chagos Archipelago, which was charted and visited by European and other mariners; in modern times they have no civilian population and fall under the administration and conservation rules of the British Indian Ocean Territory.

Sitting in the central Indian Ocean as part of the Chagos Archipelago, the Egmont Islands are remote and isolated from major landmasses, within the maritime territory administered as the British Indian Ocean Territory.

  • Access restrictions: Access is highly restricted because the islands lie within the British Indian Ocean Territory and the surrounding area is subject to conservation and administrative controls.
