Þórsmörk es un destino de senderismo ubicado en el sur de Islandia entre los glaciares Tórkajökull y Eyjafjallajökull. Este valle de alta montaña presenta picos montañosos dramáticos, formaciones de riolita coloridas y cascadas rodeadas de campos de lava cubiertos de musgo. Los senderistas recorren múltiples senderos que conectan tres refugios de montaña, encontrando terrenos diversos desde llanuras volcánicas hasta fuentes geotermales cálidas en la región.
Þórsmörk is a protected nature reserve in the southern highlands of Iceland, situated approximately 150 kilometers east of Reykjavik at the convergence of three glacier systems: Eyjafjallajokull, Myrdalsjokull, and Tindfjallajokull. The area serves as the southern terminus of the Laugavegur trail and the northern terminus of the Fimmvorduhals trail, making it one of the most significant hiking junctions in northern Europe. Access is strictly limited to high-clearance 4x4 vehicles and scheduled highland bus services due to unbridged glacial river crossings on all approach roads.
