The main industries are is agriculture and forestry. Local traditions includes carpentry, wood carving, painting and weaving.

Heidal Church is a cruciform church as are most of the churches in Gudbrandsdalen. 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).
