Långfjället

Långfjället Nature Reserve covers a vast area of 68,000 hectares, including Långfjället itself, the Dyllen area, and Juttulslätten. The region boasts high natural values with primeval forests and extensive marshlands. It's a sought-after mountainous area, particularly around Grövelsjöns Mountain Station and the southern part of the Kungsleden trail.

The landscape is characterized by flat low mountains interspersed with forested valleys and a level marsh area to the east. The mountains are grouped in three northwest-southeast ridges separated by Grövlan's, Storån-Hävlingen's, and Hågan's valleys. Most peaks reach around a thousand meters above sea level, with Storvätteshågna, Svealand's highest point, reaching 1,204 meters above sea level. Juttulslätten is bordered by occasional low mountains at around 900-1,000 meters above sea level, while the plateau itself sits at approximately 750 meters above sea level. Remnants of the southernmost Sami settlements are visible in the form of remains from the Lappland camps constructed around the turn of the century. Isolated lavvus and other buildings are found at locations like Slagufjällets Lappläger, Hävlinghällorna's Lappläger, Hågålägret, and Grövelsjön. Throughout the area, especially in Grövlan's valley, old systems of pitfall traps are present. The reserve is nearly entirely within the year-round grazing area of the Idre Sami village and is utilized almost all year. Fishing is most extensive in the Storån-Hävlingen system, but active fishing also occurs in Hågån, Foskan, Grövlan, and other larger lakes and watercourses. Rental cabins are available at Särsjön, Hävlingstugorna, and Stor-Våndsjön and are heavily utilized year-round. Rowboats and canoes can be rented at Hävlingenstugorna. Activities in the area, primarily between Hävlingen and Grövelsjön, include mountain hiking, fishing, cross-country skiing, canoeing, berry picking, and some downhill skiing. The area is highly frequented, with peak visits during the summer and early spring. Numerous snowmobile, winter, and summer trails originate from Grövelsjön and Lövåsen, with Storvätteshågna or Hävlingenstugorna as common destinations. The most renowned trail is the pilgrim's path passing through the southern tip of Grövelsjön. West of Grövlan, several trails lead towards Stora Olån, where a wind shelter is located, towards Sylen in Norway, and towards Valdalsbygget, where a summer pasture farm serves as a rest cabin. Rest cabins are situated at Foskbäcken, Töfsingen, Slugusjön, and at two locations along Storån with two open-fronted lean-tos arranged as shelters. At the Hävlingen system, numerous rest cabins are available. The Swedish Tourist Association operates a cabin with 20 sleeping places at Storrödingtjärn.
