The Mount Sonfjallet is slightly round in shape and filled with large boulders. Located in the Swedish province of Harjedalen, the Mt. Sonfjallet rises to 4,193 feet or 1,278 meters above the sea level on top of the pine forests in central Sweden. Surrounding this majestic peak is an expanded forest area which was turned into a national park in 1909 and named after the Mount Sonfjallet.
Thus the Sonfjället National Park is now one of the oldest national parks’ of Europe. The park covers an area of 103 km² and guards the slopes of the mountain and the thick carpets of reindeer moss from too much grazing. The national park is home to various species of animals namely the resident bear tribe, wolves, large elk tribe, lynx and much more. The park is rich in birdlife and while trekking on the mountains you will easily see those ptarmigan, golden plover, snow bunting, rough-legged buzzard, brambling, goshawk and various species of owl hidden under cover of the trees.
The whole area around the Mount Sonfjallet is covered with large boulders that crisscross few streaming lakes. The noteworthy feature of mountain area is its boulders as these rocks are checkered patterns and the shape is brought about by erosion brought about by severe frosts. A greater part of the mountain is bare. It is because the bedrock is made up of acidic quartzite that prohibits plant growth. The only plants that survive here are the alpine bear berry bushes and the crowberry.
The Mount Sonfjallet alone covers an area of 1,761 acres whereas the area of Sonfjallet National Park below is 6,479 acres half of which is covered with coniferous forest. The park has overnight cabin and quite a few shelters for setting up camps for adventure seeking visitors on the eastern boundary of the park beside the Valmen River.
