Dimmuborgir is a dramatic expanse of lava fields, caves and nature reserves located in the Lake Mývatn area of north Iceland. Steeped with folklore, it is surrounded by mystical stories about trolls, ogres and the Icelandic Santa Clauses who are said to reside within its many hidden chambers. Dimmuborgir has become increasingly popular for travellers due to its stunning natural beauty, its close proximity to the geothermal Námaskarð Pass, the hot spring cave Grjótagjá, and the dramatic Krafla fissure. It was also recently featured on HBO's Game of Thrones, making it all the more incredible to explore!
