Not only do the mountains around Landmannalaugar shimmer in bright colors, but stones of all shades can also be found in this valley. The valley is crossed before the ascent to Blahnukur. A small river further enriches the colorful backdrop at the foot of Blahnukur.

Both tributaries are very hot, but the water cools down considerably after a few meters. Very crowded! No changing rooms: you have to make do with the towel you brought with you.

When you climb up to Brennisteinsalda you have a great view of the Laugahraun lava field and the geothermal area. Even if you don't want to climb all the way up, you still have a great view here.

Please only climb the summit with good hiking boots and possibly hiking poles (approx. 3 hours round trip) Magnificent views of the colorful Liparit Mountains all around. The Bláhnúkur is a volcano in the Icelandic highlands that is almost a thousand meters high. Between it and the Laugahraun lava field lies the Graenagil gorge, through which several hiking trails lead.
