Experience rough volcanic terrain, icecaps/glaciers and unbridged rivers. Þórsmörk, valley of the Thunder God Thor, sits amongst three sparkling ice caps, Mýrdalsjökull, Tindfjallajökull and Eyjafjallajökull. Sights include Gígjökull where powerful glacial floods escaped during the 2010 Eyjafjallajökull eruption. Our local guides will vividly tell you much about this eruption, including stories only locals know about.
