The glacier–tongues Fláajökull and Heinabergsjökull stretch far down into the district. It is possible to drive to Fláajökull along Hólmsá. Heinabergsjökull divides into two arms around the mountain Hafrafell, north of which there is another mountain, Snjófjall, with a peculiar glacier hollow on the south side.
Hiking routes in the area:
The valley Vatnsdalur (“Water (or lake) valley”) on the western side of Heinabergsjökull often collects large quantities of water dammed up by the glacier, Heinabergsvötn. Once in a while this water forces its way out under the glacier, causing big floods in the rivers. The low mountain Jökulfell (150m) in front of Fláajökull was hidden by ice at the beginning of the century, but began to come into view around 1920.
