Mýrdal

Mýrdal is a valley region in southern Iceland along the south coast. It centers on the Mýrdalur valley and is traversed by the Ring Road (Route 1), linking coastal communities such as Vík í Mýrdal with inland areas. To the north of the valley lies the Mýrdalsjökull glacier, which covers the Katla volcanic system. The coastal zone features dramatic landscapes, including the Reynisfjara black-sand beach near Vík and the Reynisdrangar sea stacks, as well as the Dyrhólaey promontory.

Geology and geomorphology in the area reflect glacial and volcanic activity, with basalt formations, outwash plains, and frequent changing weather. The region is a popular destination for sightseeing, hiking, and guided glacier tours, and is a key stop along the south coast of Iceland.

Natural hazards include volcanic activity from Katla, which can cause jökulhlaups (glacial outburst floods) that have historically affected the area and infrastructure along Route 1.
