Dyrfjöll
The magnificent 1136 high mountain range Dyrfjöll near Borgarfjörður Eystri draws its name from the iconic "door" in the middle of the range. Its shape is very different from many other mountains in Iceland with steep vertical valls and the big door-like gap (856 m high) in the middle. Dyrfjöll is an old volcano formed during or before the last Ice age.
The hiking trail up the ridge is very diverse with untouched mossy areas, clear pools and glacier landscapes but only suitable for experienced hikers under guidance. The view from the top is breathtaking.
