Holaskogur (The Forested Mounds) is a deforested area of the southern Gnupverja summer pastures. It is located within a larger area called Haf between the two hydroelectric power stations at Burfell and Sultartangi. It is connected to the main road by a mountain track, which continues along the electric grid to farm Tungufell in the Hrunamanna County. An rough track from Valley Thjorsardalur also gives access to Holaskogur.
The accommodation at Holaskogur is popular among those who are travelling in the interior.
