⚠️ SAFETY WARNING: Due to its status as a highly restricted military zone and the complete absence of civilian infrastructure, the UK government strictly controls and limits access to this territory. Authorities indicate that this is not a tourist destination, and permits are rarely granted to civilians. While not rated by all agencies, the consensus among the UK, USA, and others is that general travel is prohibited or strictly limited to official business. Families are strongly urged to consult their own government's official travel advisory before considering a trip, as circumstances and risk assessments vary.

The British Indian Ocean Territory (BIOT) encompasses the Chagos Archipelago, a collection of roughly 55 islands located halfway between East Africa and Indonesia. The largest and most significant island is Diego Garcia, which functions exclusively as a joint military facility for the United Kingdom and the United States. Families planning travel in the Indian Ocean region should be aware that BIOT does not offer the accessibility found in the Maldives or Seychelles. There are no commercial airports, hotels, tourist beaches, or family-friendly amenities.

Geographically, the territory is stunning, featuring vast coral atolls and lagoons. The waters surrounding the islands form one of the world's largest Marine Protected Areas, safeguarding pristine coral reefs and diverse marine life, including sea turtles and coconut crabs. However, this environmental preservation is largely due to the lack of human presence. Access to these waters is tightly regulated, and yachts seeking safe passage must obtain permits weeks in advance, with strictly limited anchorage rights.

For families, the logistical barriers make travel here impossible for a standard vacation. There are no medical facilities for civilians, no banking services, and no public transport. The territory is inhabited only by military personnel and contractors. While the region is fascinating for its geopolitical history and marine biology, it remains a destination suitable only for authorized personnel, not for family exploration or leisure travel.

Adventure / Expedition Travellers

Yacht crews must secure a mooring permit before entering BIOT waters. Permits are only valid for the outer islands and do not grant access to Diego Garcia. Comprehensive insurance covering medical evacuation is a mandatory prerequisite for permit approval.

General Travellers

Casual tourism is not allowed. You should not plan or attempt to visit the islands for leisure purposes as entry will be denied.
