Folldal is located along the northwestern border of Hedmark county. It is bordered in the north by Oppdal (in Sør-Trøndelag county) and Tynset, in the east by Alvdal, in the southeast by Stor-Elvdal, and to the southwest and west by Sør-Fron, Sel, and Dovre (all in Oppland county). Folldal Municipality has the country's highest administrative center (712.5 meters above sea level) and has picturesque scenery with mountains and valleys. The village lies at the foot of Rondeslottet mountain and Snøhetta mountain. The area also has many interesting geologic features from the last Ice Age. Norway's longest seter valley, the 55 kilometer long Einunndalen, lies within the municipality. The Einunndalen is still actively used for summer grazing at the seters (mountain summer farms) established in the 1700s. Almost half of the municipal land is protected as conservation areas and national parks, including parts that are included in the Rondane National Park and Dovrefjell-Sunndalsfjella National Park.
