Bouvet Island, Norway is completely isolated from the rest of the world, and the only landmass is within approximately 2,000 kilometers, which is roughly the size of the whole European continent. The island itself is super small, only 49 square km in total area, with most of the land coated with a thick ice glacier, and enclosed by cliffs set atop an active volcano. The average year-round temperature hovers at -1 degrees Celsius.
Even getting to the island is quite difficult, given the ice and vertical cliffs. The island and surrounding waters are a protected nature preserve and the Norwegian government rarely, if ever, given access.
