Jotunheimen is a large mountain range in Norway. The many summits are over 2,000 meters above sea level, and the range contains no less that 20 of Norway's highest peaks, including Galdhøpiggen, Norway's highest mountain, and the second largest, Glittertind, only 5 meters shorter. It is also hosts a large number of both small and large glaciers.

Most of Jotunheimen has status as national park, meaning that special regulations apply. No motor vehicles are allowed, which makes the area ideally suited for hikers and climbers that enjoy the experience of virtually untouched nature.

Etymology: Jotunheimen is named after the giants of Norse mythology, and it literally means the Home of Giants.
