- Visiting address: Tvärstupet , Borlänge
Tvärstupet became a nature reserve already in 1947. The reserve has a varying nature with both forest, the actual steep, a marsh and a tarn by the name Tvärstupstjärn. Tvärstupet is a southern slope which means that both night and day temperature is higher here than in the surrounding areas, which means a lot to its vegetation.
