Heidal is a side valley of the Gudbrand Valley. The valley runs northwest from the village of Sjoa on Highway E-6, some 10 km before the community center of Otta. Heidal is rich in beauty and tradition, lying along the narrow valley of the Sjoa River. The Sjoa runs from Lake Gjende in the Jotunheimen Mountains, through Heidal and down to the Gudbrandsdalslågen river. It has a high concentration of older protected timber houses and farmsteads. The main industries are agriculture and forestry. Local traditions includes carpentry, wood carving, painting and weaving.
Heidal Church (Heidal Kirke) was built during the period 1937-41 as an exact replica of a 1754 church which was destroyed after being struck by lightning in 1933. Heidal Church is a cruciform church as are most of the churches in the Gudbrand Valley. The church was built of wood. It has about 300 seats and three galleries. The church was designed by architect Bredo Berntsen (1877–1957). The altarpiece is a work by the Norwegian sculptor Jakob Klukstad. Near the church stands the Bjølstad Chapel (Bjølstad-kapellet). Bjølstad Chapel seating 75 and dates from around 1531.
Some locations allow guided tours, including Søre Harildstad farm and Bjølstad Chapel. Farms like the Bjølstad Farm are not open to the public. At the Bjølstad Farm the newest building was constructed in about 1820 and the farm has been in the same family since the 13th century.
