This Nordic island is a fascinating, almost alien place-as evidenced by sci-fi films shot there such as Interstellar, Prometheus, Thor: The Dark World and Rogue One. Where else can you visit ice caves, bathe in a blue lagoon, see raging waterfalls, gaze at the northern lights, go whale watching and walk on a glacier? Plus, there's dynamic and quirky Reykjavik, the capital and largest city, which is well worth exploring.
