Herdubreid (Herðubreið) is one of the famous mountains in Iceland highlands. The mountain stands 1.682 meters above sealevel and is visible from far away. Herdubreid stands in the middle of Odadahraun (Ódáðahraun) desert and is in short distance from Askja volcano. 

The large lavafield in wich Herdubreid stands in was formed during a powerful eruption in Trolladyngja (Trölladyngja). Near the mountain is a great campingground and hiking trails. Around the area are many great natural wonders worth seeing.
