Kalvehøgde is a 10 km long massif in the southernmost part of the Jotunheimen mountain range. The northern part of the massif lies within Jotunheimen National Park. The massif rises quite slowly from lake Bygdin, and ends in an extremely steep wall to the north. The wall is about 500 to 700 m high. On the northern side of the massif, there are several glaciers, with Leirungsbrean as the greatest. On the southern slopes there are two smaller glaciers – the Kalveholobrean glaciers. All the glaciers have retreated in the later years. The massif contains ten 2000 m summits, but the northwesternmost (in the foreground on the photo to the right) and the two easternmost (not visible) are normally seen as independent mountains. The prominence of most of the summits are less than 100 m, and most of the massif is a broad ridge or a plateau which makes it very popular among mountain skiers. The proximity to the National Route 51 adds to the popularity, and the massif is one of the definitely most visited in Jotunheimen.

Because of the number of summits, there has been a need for more distinct names for all the seven summits, and the National Map Institute has decided upon the name Munken (the Monk) for the northeastern plateau – seen in the lowermost picture, Mugna (probably meaning huge) for the two central summits, Kalvehøgde (reindeer calf mountain) for the three western summits, and lastly Nordre Kalveholotind (northern reindeer calf hole peak) for the southwestern summit, which is the only summit which has a prominent, steep wall on the southern side of the massif.

The massif is built mostly by gabbro rocks, a hard and resistant rock. The southern slopes and the plateaus consist mostly of talus, and there is very little plant life except lichen, moss and ranunculus glacialis. Snow sparrows and mountain grouses are frequent and reindeers can be seen, but they mostly prefer the grassy slopes down towards lake Bygdin.

The Eastern Kalvehøgde and the Mugna summit were both climbed in 1820 by the two students Balthazar Mathias Keilhau and Peter Christian Bianco Boeck, both later prominent scientists at the university of Christiania. This is considered to be the first real mountain expedition in Norwegian history, and these summits were the first to be climbed by the two friends. The rest of the summits have unknown first ascents.
