Kerlingarfjoll is a beautiful and colourful mountain range in the Icelandic highlands that hosts the third largest geothermal area of the interior.
This is a young range of mountains, unusually created from rhyolite and both dark and bright tuff stone, about 10,000 years old. A few small glaciers grace a number of their tops. The mountains constantly change colours depending on the light, the sun and the time of day. Kerlingarfjoll are operated as a highland resort, providing food services and accommodation to guests in the area.
