The scenery of Forollhogna consists of large alpine areas, with gentle slopes rising from the valleys below—an area often referred to as "the gentle mountains". Here are thriving villages and a lush cultural landscape formed by the region's farming traditions. For centuries the mountain farms have been in use during the summer, and many still are. This is the setting of Forollhogna National Park, Norway's 19th park to be so designated.
The name is a composition of two words. The last element is the finite form of hogn which means "defender" or "protector" (this tall and impressive mountain mark the border between Trøndelag and Hedmark). The first element comes the name of the lake in the central part of the park: Forollen (Forollsjøen).
