Þórsmörk the Valley of Thor
Þórsmörk (Thorsmork) is a magnificent lushly vegetated mountain valley and designated nature reserve. The “true” Þórsmörk is the area between the Krossá, Þrönga and Markarfljót rivers, the valley is closed at the far end by the magnificent Mýrdalsjökull glacier. The notorious Katla volcano nestles ominously and quite restlessly at the moment, under the Mýrdalsjökull icecap. These natural boundaries define Þórsmörk. Although, many people mention Þórsmörk when they are talking about a wider area than this. The name Þórsmörk has some interesting links with Norse mythology and the Norse God Þór (Thor), the Thunder God with the famous hammer, Mjölnir. So the name means Þór’s wood, a really great name for this richly wooded valley!
Þórsmörk climate, fauna and scenery
Sitting as it does within the embrace of the high mountain glaciers Þörsmörk Nature Reserve enjoys a climate which is more gentle and favorable than that in the surrounding area. The valley is home to birch and other trees, moss, ferns, more than 170 seminiferous plants and shrubs which all grow abundantly in this sheltered green paradise. It also helps that horses and sheep have not grazed here for more than 100 years giving vegetation the chance to flourish unimpeded! This fertile birch scented area contrasts starkly against the trio of towering mountain glaciers above it, Tindfjallajökull, Eyjafjallajökull, and Mýrdalsjökull. Following a trail up above the valley will take you close to the glaciers and provide a magnificent aerial view over the whole area. Þórsmörk Nature Reserve is a mind-blowing dream scene!
The journey through south Iceland to Seljalandsfoss, then on to Þórsmörk is exciting. Crossing the river Krossá (yes, Krossá literally means ‘the cross river’) is an adventure. Some days the flow of this glacial river is bigger and more forceful than others. A word of warning, go very carefully and never ever attempt this in a regular car!
What to do in Þórsmörk
The Icelanders come here to relax among sweetly scented birch trees, hike and to ride on horseback as their ancestors did when they followed the Laugavegur trail in ancient times.
