Named after the Norse god Thor (Þór), this protected reserve is a hiker's paradise, with scenes seemingly plucked from an enchanting fantasy. The verdant realm is clasped by snowcapped mountain ridges, wild-flower-filled valleys, curling gorges, icy rivers and three looming glaciers (Tindfjallajökull, Eyjafjallajökull and Mýrdalsjökull). The glaciers protect this quiet spot from some of the region's harsher weather; it is often warmer or drier in Þórsmörk than nearby areas.
The higher, northeastern reaches of the area are known as Goðaland (Land of the Gods), which is – as the name suggests – divine. Rock formations twist skyward like the stone arches of an ancient cathedral. Fluorescent Arctic flowers burst forth from spongy emerald moss bringing brilliant slashes of colour. At its higher altitudes, Goðaland often has rougher weather than Þórsmörk.
