The Sylan mountain range is located on the border with Sweden. Both countries share the huge, lumpish mountains, rising up from the eroded and rocky plains. These gabbro rock formations more or less survived the grinding forces of the glaciers in the ice age. The highest mountain – Helagsfjället, 1797 m - is located in Sweden. Storsylen (1762 m) is another fine mountain, with its peak just on the Norwegian side of the frontier.
Sylan also refers to a much wider area, reaching out to Trondheim in the west, Nord-Trøndelag in the north, Swedish Sylarna in the east and Femundsmarka in the south. The entire region is a large hikers paradise, with many staffed huts on the Swedish side, and some three staffed huts plus seven self-service huts in Norway. In winter, the area is popular as one of the largest cross-country skiing regions.
Walking is easy, because of the modest differences in height. Lakes and rivers can be fished, in spite of hydro-electrical works for which a nature reserve had to be flooded. Reindeer can be seen trotting over the barren fields. This is a spacious landscape.
