Hofmannaflot is a flat plain on the eastern side of Mt. Armannsfell and north of the National Park Thingvellir. It is framed with low mountains on three sides and open towards the south. Two of the main approaches of the Parliamentary Plains, from the West and the North cross paths there.
Secondary mountain roads have taken their places and nowadays many more travellers pass through than in the past. These roads are the so-called Kaldidalur Route, the Uxahryggja Route and the Linuvegur Route (4wd). The plain was cultivated for hay making in the past and during winter it is hidden under a thick layer of snow. The melt water in spring creates a temporary lake, sometimes frozen over and a dangerous trap for motor vehicles.
According to the legends, this plain was the meeting place of the giants and giantesses of the country.
