Saint Helena, Ascension and Tristan da Cunha Travel Guide

Saint Helena, Ascension, and Tristan da Cunha are three genuinely distinct UK overseas territories bundled under one name, and each runs its own entry process. Saint Helena itself offers an e-Visa for stays up to 183 days, six months, and a visitor without valid medical insurance or proof of means to support themselves on arrival can be refused entry by the immigration officer, a real discretionary check rather than a formality. Ascension Island introduced its own new e-Visa system, and the large majority of visitors need it, there is no visa on arrival option there at all, and a passport needs at least six months of validity to cover the full length of your stay on Ascension specifically.

Tristan da Cunha is the most restrictive of the three: visiting requires the prior permission of the Island Council itself, not just a standard visa application, along with a confirmed and fully paid return passage, comprehensive travel and medical insurance covering treatment and evacuation all the way to Cape Town, and proof of sufficient funds for the visit. This is a genuinely different tier of arrangement from either Saint Helena or Ascension, reflecting Tristan da Cunha's status as one of the most remote inhabited places on Earth.
