#12: Bouvet Island, Norway
Bouvet Island sits alone in the South Atlantic, far from normal shipping routes and almost completely covered by glaciers. Norway protects it as a nature reserve, and even official landings are hazardous. The main reason it is nearly impossible to visit is unstable cliffs, ice, storms, and strict access rules.

Even its own discoverer struggled with it. Jean-Baptiste Charles Bouvet de Lozier could not land in 1739, and later expeditions also had trouble relocating or reaching the island. Modern visitors usually need specialist ships, helicopters, permits, and a lot of luck with the weather.
