Check out the Volcano Huts in the Þórsmörk Nature Reserve. Many people come here for the endless hiking trails and stay for a few days, while others come for a short stop and a nice picnic. You can choose between short and easy or the longer and more demanding trails. The most popular trails in Þórsmörk are well marked and they have maps in English which provide information about the trails and give you a little insight into the volcanic landscapes of Þórsmörk and its history.
The Laugavegur Hiking Trail stretches 55 kilometres across the southern Icelandic highlands and connects the two nature reserves, Landmannalaugar and Þórsmörk. Most people cross the Laugavegur Hiking trail in 3 – 5 days, starting in Landmannalaugar and ending their trip in Þórsmörk although you can choose shorter parts of the trek/trail if you wish. Accommodation is offered in six mountain huts and on camping grounds along the trail.
