The park was opened in 2004 and is about 441.5 km². The park borders on the Stråsjøen-Prestøyan natural reserve and includes a large spruce forested area (the Roltdal is the largest roadless mountain valley in Sør-Trøndelag) as well as the Skarvan mountainous region which is typical of the Trøndelag region, both in cultural and natural history.
The Skarvan mountains, which stretches from Ruten to Fongen is the most notable mountainous area in the region. Trondhjems Turistforening maintains a network of touring trails connecting Roltdalen to the trail network of Nord-Trøndelag Tourist Association and trails in the Sylan area.
