Holuhraun is the site of a volcanic eruption which began on 29 August 2014 and produced a lava field of more than 85 km2 (33 sq mi) and 1.4 km3 (0.34 cu mi) – the largest in Iceland since 1783. It´s a rather surreal experience to visit this enormous lava field which looks like a volcanic island in the middle of a black sand desert.
This is one of the hardest to reach locations in Iceland, deep in the highlands and the only trail leading to the place goes 20 km through a deep sand and when it´s windy the trail disappears completely.
