Forollhogna National Park, also called Forollhogna nasjonalpark in Norwegian, is located in the counties of Trøndelag and Innlandet in Norway. The park has a wide variety of plants and is an important habitat for wild reindeer. The park covers parts of several municipalities. In Innlandet county, these include Tynset, Tolga, and Os. In Trøndelag county, the park includes Holtålen, Midtre Gauldal, and Rennebu.

The area around the mountain Forollhogna has large alpine regions with gentle slopes that rise from the valleys below. This area is known as "the gentle mountains." There are lively villages and a rich cultural area shaped by the region's farming traditions. For many years, mountain farms have been used during the summer, and some are still used today. This is the setting of Forollhogna National Park, which is Norway's 19th national park.

Name

The name is made up of two parts. The second part comes from the word "hogn," which means "defender" or "protector." This tall and impressive mountain marks the border between Trøndelag and Innlandet. The first part of the name comes from the lake in the central part of the park, called Forollen (Forollsjøen).
