Thórsmörk (Icelandic: Þórsmörk) is a mountain ridge in Iceland that was named after the Norse god Thor (Þór). It is situated in the south of Iceland between the glaciers Tindfjallajökull and Eyjafjallajökull. The name "Thórsmörk" properly refers only to the mountain ridge between the rivers Krossá , Þröngá and Markarfljót,[1] but is sometimes used informally to describe a wider area that includes the region between Thórsmörk and Eyjafjallajökull.

In the valley, the river Krossá winds between the mountains. The valley is closed in between glaciers, Mýrdalsjökull being at the rear end of the valley. This leads to an especially warm climate, better than in the rest of south Iceland. In the protected valley, there is green vegetation of moss, fern, birchwood and other small shrubs.

Landmannalaugar (Icelandic pronunciation: [ˈlan̥tmanːaˌløiɣar̥], the people's pools) is a region near the volcano Hekla in southern section of Iceland's highlands.

The Landmannalaugar area is a popular tourist destination and hiking hub in Iceland's highlands. The area displays a number of unusual geological elements, like the multicolored rhyolite mountains and expansive lava fields, not far from the service center. The many mountains in the surrounding area display a wide spectrum of colors including pink, brown, green, yellow, blue, purple, black, and white. Two of the most popular mountains among hikers are Bláhnjúkur (meaning "blue peak") and Brennisteinsalda (meaning "sulphur wave").
