Egmont Islands

The Egmont Islands or Egmont Atoll, also known as Six Iles, is an uninhabited atoll under British rule. They are one of the few emerged coral atolls that make up the Chagos Archipelago, British Indian Ocean Territory.

This small atoll lies less than 10 km south of the southwestern rim of the Great Chagos Bank submerged coral reef. The nearest island is Danger Island on the Great Chagos Bank, less than 30 km due north. Its total size is 29 km², including the lagoon and the fringing coral reef. The land area totals about 4 km².

There are two passages into the lagoon along the Northern Rim, Fausse Passe in the northeast and a wider passage in the northwest. The Egmont Islands are one of the favorite anchoring spots for itinerant yachtsmen passing through the Chagos.
