Tristan da Cunha, British Overseas Territory

The volcanic island of Tristan da Cunha in the South Atlantic boasts a population of 258 people with only nine different last names.

The locals speak English, but have also invented their own dialect with words derived from Scottish, English, St Helenian, South African, American, Dutch, Italian, and Irish, reflective of their various places of origin.

South Africa is the nearest country to this British Overseas Territory, which is said to be the most remote inhabited archipelago in the world.

To get there, you have to time your visit one of the three ships that make nine trips from Cape Town each year — a journey of 1,732 miles.
