The park includes parts of the Sørdalen valley (canyon), the large lake Geavdnjajávri, and the mountain Rohkunborri.

The large lakes Altevatnet and Leinavatnet both lie just north of the park boundary.

[1] The nature varies from rich boreal deciduous forest on the lower elevations to alpine tundra higher up.

The park is home to brown bears, wolverines, and lynx, as well as the snowy owl, gyrfalcon, and reindeer (with Sami owners).

The mountains on both sides of the canyon reach up to 1,500 metres (4,900 ft) above sea level.
