Chagos Marine Protected Area

There is no tourism in the territory and no scheduled passenger service of any kind. Access to Diego Garcia is limited to people connected to the naval support facility or to the territory's administration, and the outer islands can be reached only under a permit issued for safe passage by yacht. Entry requirements for any journey vary by passport, so check your specific requirements on the destination page at Yoogo.

The archipelago has been administered by the United Kingdom as the British Indian Ocean Territory since 1965. In May 2025 the United Kingdom and Mauritius signed a treaty providing for Mauritius to exercise sovereignty over the archipelago, with the United Kingdom retaining rights over Diego Garcia under a 99 year lease. Implementation was still working through the United Kingdom Parliament into 2026, so confirm the current position before making any plans.

The United States dollar is the currency in use, reflecting the American presence at the naval support facility on Diego Garcia. Pounds sterling are also accepted in some settings on the base. There are no public banks, cash machines, or exchange facilities anywhere in the territory.

The territory has no civilian population and no crime problem in the ordinary sense, but it is one of the most remote places on earth. The nearest substantial land is more than 1,500 kilometres away, and any medical emergency on the outer islands means waiting for a vessel or an air evacuation. Yachts on permitted passage are expected to be entirely self sufficient.

Diego Garcia is served by military and charter flights and has an internal road network on the base, where traffic drives on the right. The outer islands have no airstrips, no roads, and no settlements, so movement between atolls is by boat only. There is no public transport of any kind.

The calmest conditions fall between April and October, outside the north west monsoon, which is when most permitted passages are timed. Cyclones are rare this close to the equator, but squalls and sudden wind shifts are common year round. Permits set their own date windows, and those take precedence over the weather.

English is the language of administration and of daily life on Diego Garcia. Filipino and Mauritian contract staff make up much of the civilian workforce, so Tagalog and Mauritian Creole are also widely heard. Chagossian Creole survives among the displaced Chagossian community, mostly in Mauritius, the Seychelles, and the United Kingdom.
