Dimmuborgir is one of Iceland’s most well-known tourist attractions. The interesting formations, the walkable paths, the close proximity between the lava fields, Lake Mývatn, and the Hverfjall volcanic crater, and the fact that it was featured prominently as part of the lands beyond the wall in Season 3 of Game of Thrones make it a must see destination if you ever find yourself in the northern part of the country.
