Thorsmork valley was named after the Norse god Thor. It‘s situated in the south of Iceland, between the glaciers Tindafjallajokull, Myrdalsjokull and Eyjafjallajokull. Thorsmork is one of the most popular hiking areas in Iceland.
Many different tours are available in the area, from hiking on the glaciers to trekking (e.g., Laugavegur up to Landmannalaugar) or smaller hiking excursions, such as to the canyon Stakkholtsgja with its waterfall, or the five small day treks to the summits of surrounding peaks, with rewarding views.
Thorsmork is famous for having a great variety of natural features. It has been protected since 1921, in the care of the Forestry Service. Weather in Thorsmork is often warmer than nearby, since it is protected by the three glaciers surrounding it. In the protected valley there is green vegetation of moss, fern and birch wood.
Thorsmork and the 2010 eruption
The river Krossa winds between the mountains, a very cold river coming down from the glaciers. Due to Thorsmork‘s close proximity to many volcanoes, e.g. the mighty Katla that rests under Myrdalsjokull, the landscape has been moulded and affected by eruptions and floods. During spring 2010 the eruption in Eyjafjallajokull (the one that stopped all flights in Europe for some time) much of the area was covered in thick layer of volcanic ash. The fragile nature of Thorsmork needed several months to return to normal.
