The Ruff lek on Langvassmyrane is the only known phenomenon of its kind on Hardangervidda. Every year it attracts hens from the whole plateau. The marsh is also the richest wetland in the county. This green oasis is located in a rocky moraine landscape a few hours walking distance south of Dyranut.
The old stone church at Eidfjord has an open position on the terrace at Lægreid. In a diploma from 1310 it transpires that Torgeir on Sponheim donated a gift for the erection of the church in Eidfjord. Thus we can assume that the church was under construction at the time. The elements in the style confirm such a dating.
