Jotunheimen is a mountainous area of roughly 3,500 square kilometres (1,400 sq mi) in southern Norway and is part of the long range known as the Scandinavian Mountains. The 29 highest mountains in Norway are all located in the Jotunheimen mountains, including the 2,469-metre (8,100 ft) tall mountain Galdhøpiggen. The Jotunheimen mountains straddle the border between Innlandet and Vestland counties.

The Scandinavian Mountains or the Scandes is a mountain range that runs through the Scandinavian Peninsula. The western sides of the mountains drop precipitously into the North Sea and Norwegian Sea, forming the fjords of Norway, whereas to the northeast they gradually curve towards Finland. To the north they form the border between Norway and Sweden, reaching 2,000 metres (6,600 ft) high at the Arctic Circle. The mountain range just touches northwesternmost Finland but are scarcely more than hills at their northernmost extension at the North Cape.
