Haugsöræfi, a mountain range east of Hólsfjöll, up to 1,000 m high. There is a large lake there called Haugsvatn. An old route, about 70 km long, went across there between Vopnafjörður and Hólsfjöll, Vopna­fjörður then being the trading post for the farmers. The mountain range gets its name from one of its peaks, Haugur (965 m).
