The Fulufjället massif is a high plateau deeply gouged by several rivers that flow into the mighty river Dalälven, which, far downstream, creates the unique topography of Färnebofjärden National Park. The geography is dominated by lichen, bare mountains, and valleys with dense old-growth forest. The heaths of brush, grass and lichens are unique in the Scandinavian Mountains, a result of the absence of grazing reindeers.
