According to a map, Grimsstaðir seems to be a village at least. But in reality, it is just 4 houses in an otherwise uninhabited area. The nearest shop is 65km away with an unpaved road in between. If you want to experience loneliness, this is the place to go.
grimsstadir : Grimsstaðir farm house - we were on our own although there is room for nine persons altogether.
