Longyearbyen, Norway

The northernmost town in the world, Longyearbyen, Norway, is so cold that it's illegal to be buried there, because bodies won't decompose in the frozen ground. Instead, bodies have to be flown to the mainland for burial. Houses also have to be built on stilts so that they don't slide away when the topsoil melts in the summer.

Norwegian Airlines offers three flights a week, and it's three hours from Oslo.
