You can walk up Mælifell or to the nunatak (hill or mountain completely surrounded by a glacier) Huldufjöll, if you are properly equipped and experienced. There are also easier walks around the nearby rivers. Check on weather and route conditions before setting out.
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.
