The British Indian Ocean Territory (BIOT), an archipelago of 58 islands covering some 640,000 sq km of ocean, is a British Overseas Territory. It is administered from London and is located approximately halfway between East Africa and Indonesia.

Access is restricted and a permit is required in advance of travel.

⚠ Permit Applications – Important Update – 31/03/2026 ⚠
In light of ongoing litigation relevant to the circumstances in which the BIOT Administration may issue permits for people to enter BIOT (except for permits to enter Diego Garcia necessary for the operation of the military facility or those on official BIOTA business) we have as of 31 March 2026, paused substantive consideration of new applications for permits to enter the Territory whilst the BIOT Administration considers its position. We will update this notice as soon as there are any developments.
