The Fulufjället national park, which is situated in the northwestern part of the province of Dalarna adjoining the Norwegian border, was set up in 2002. Its surface area is 385 km2, two-thirds of which consists of bare mountain and mountain moors. There is a visitors’ centre and café along the Njupeskär trail.
The mountain consists of a flat sandstone plateau with steep forest-covered sides. The highest point is 1,042 m above sea level.
The national park’s main public attractions are the precipice from which Njupeskär, Sweden’s highest waterfall with a total height of 93 m, plunges and the spectacular erosion marks along the Göljån valley left by the freak rainstorm of 1997, when about 400 mm of rain fell in one day. The swollen river swept through the valley, eroding the rock, stripping the deposits off the slopes and breaking new channels.
Several watercourses have worn down the bedrock and exposed sandstone structures that were formed about 1,300 million years ago. Conditions have varied greatly during the millions of years after the sand was deposited. Ripple marks indicate that sedimentation took place in shallow water and mud cracks indicate that the climate was arid. The sandstone is cut through by dolerite dykes. Along the watercourses you can see stones of greenish Särna tinguanite, which is not found anywhere else except in the northwestern Dalarna area.
