You can walk up Mælifell or to the nunatak (hill or mountain completely surrounded by a glacier) Huldufjöll, if you are properly equipped. There are also easier walks around the nearby rivers. Check on weather and route conditions before leaving.
There is one campground in the area; the nearest hotels are on the Ring Road (Rte 1) and in Vík.
Buy groceries and food in Vík – there are no facilities in the isolated Mælifell ridge area.
