About Sonfjället National Park

Sonfjället National Park is a protected mountain area in Jämtland County in central Sweden, set around the Sonfjället massif and noted for its mountain moorland and subalpine environment. The park is one of the earlier national parks in Sweden and is valued for its natural habitats and wildlife.

Trails and marked routes lead across modest peaks and plateaus; the area is frequented by hikers seeking mountain scenery and opportunities to see large mammals such as moose and brown bear from a distance. The landscape combines rocky outcrops, sparse birch woodlands and open highland terrain.

The massif and surrounding land have long been used for seasonal grazing and hunting; the park was designated to protect the area’s characteristic mountain habitats and fauna. Management focuses on balancing visitor access with conservation of species and habitats.

Sonfjället National Park lies in central Sweden’s interior within Jämtland County, set inland from the Bothnian Sea and accessible from local towns and road networks that serve the region’s outdoor recreation areas.

  • Established and wildlife: One of Sweden’s older national parks, established in the early 20th century, known for mountain scenery and large mammals such as moose and brown bear.

Tips for Visiting Sonfjället National Park

  • Plan wildlife watching for early morning or late evening when moose and other large mammals are most active; midsummer daylight can be long, but dawn/dusk still gives the best chances of sightings.
  • Use the park's marked trail network and official trailheads rather than cutting cross-country; staying on signed routes protects fragile alpine vegetation and makes navigation straightforward.
  • Avoid the busiest period by visiting on weekdays or outside high July holiday weeks when local visitation peaks - you'll find trails and viewpoints noticeably quieter.
