What is the most remote inhabited island group?

The most remote inhabited island group is Tristan da Cunha, a volcanic archipelago in the South Atlantic Ocean.

Tristan da Cunha lies about 2,816 kilometres from South Africa and roughly 3,360 kilometres from South America. Its main island is about 98 square kilometres in area, and the only permanent settlement is Edinburgh of the Seven Seas. The territory also includes Gough Island, Inaccessible Island, and the Nightingale Islands, most of which are uninhabited.

The island has no airport or regular passenger service. Travel normally requires a ship from Cape Town and takes around six days, although occasional scientific, fishing, naval, or cruise vessels also visit. Its isolation has helped preserve a distinctive local community and variety of Tristanian English.

A common mix-up is Saint Helena, which is also remote but lies much closer to other inhabited places. Tristan da Cunha is part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha. The island was evacuated after a volcanic eruption in 1961, and most residents returned in 1963.
