    Overview

    Tristan da Cunha , colloquially known as Tristan, is a remote group of volcanic islands in the South Atlantic Ocean. It is one of three constituent parts of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, with its own constitution. The territory consists of the inhabited island Tristan da Cunha, which has a diameter of roughly 11 kilometres (6.8 mi) and an area of 98 square kilometres (38 sq mi); the wildlife reserves of Gough Island and Inaccessible Island; and the smaller, uninhabited Nightingale Islands. As of September 2026, the main island had 222 permanent inhabitants, all of whom hold British Overseas Territories citizenship. The other islands are uninhabited, except for the South African personnel at a weather station on Gough Island. The island has no airstrip; the only way to travel to or from Tristan is by ship. It is a six-day journey from Cape Town, South Africa, and some cruises depart from Ushuaia, Argentina. The island of Tristan da Cunha is considered to be the most remote inhabited place in the world.
