Jotunheimen contains Jotunheimen National Park, which was established in 1980 and covers an area of 1,151 km². The Hurrungane mountain range is also inside the national park with the sharpest peaks in Jotunheimen. Adjacent to the national park border is Utladalen Nature Reserve which covers the Utladalen valley and the mountain Falketind, amongst others.
Jotunheimen is very popular with hikers and climbers, and the Norwegian Mountain Touring Association maintains a number of mountain lodges in the area, as well as marked trails that run between the lodges and others that run up to some of the peaks.
The image from Gjende shows a cliff trailing down into the lake. At its base there is a popular guest house called Memurubu. The picture is taken from Gjendesheim, a starting point for hiking into the mountain range. There is a very popular trail along Besseggen that follows the edge of the mountainous range to the right, which it is named after.
There is a National Tourist Route, the Sognefjell Road, from Skjolden to Lom and another road, the RV 51, from Gol to Vågå through the special area of Valdresflya.
Jotunheimen includes the highest mountains in Norway.
Galdhøpiggen reaches 2469 m a.s.l., while Glittertind’s ice-covered summit is only a few metres lower.
The wildest and sharpest peaks in Jotunheimen are in the Hurrungane range, where Store Skagastølstind (2403 m a.s.l.), the third highest summit in Norway, reigns supreme.
The largest glacier is Smørstabbreen, covering some 15 km2.
