Rondane is a typical high mountain area, with large plateaus and a total of ten peaks above 2,000 m (6,560 ft). The highest point is Rondslottet ("The Rondane Castle") at an altitude of 2,178 m (7,146 ft). The lowest point is just below the tree line, which is approximately 1,000 to 1,100 m (about 3,300 to 3,600 ft) above sea level. The climate is mild but relatively arid. Apart from the White Birch trees of the lower areas, the soil and rocks are covered by heather and lichen, since they lack nutrients. The largest mountains are almost entirely barren; above 1,500 m (5,000 ft) nothing but the hardiest lichens grow on the bare stones.
The mountains are divided by marked valleys through the landscape; the deepest valley is filled by Rondvatnet, a narrow lake filling the steep space between the large Storronden-Rondslottet part and Smiubelgen ("The blacksmith's bellows"). The central massif is also cut by "botns": flat, dead stone valleys below the steep mountain walls of the peaks. Generally, Rondane does not receive enough precipitation to generate persistent glaciers, but glacier-like heaps of snow can be found in the flat back valleys.
The centre of the Park is the Rondvatnet lake, from which all the peaks beyond 2,000 m (6,560 ft) of altitude can be reached in less than one day's walk. In this central region and north of it, the altitude is quite high compared with the flatter plateaus of the south. Rondane has ten peaks over 2,000 m, Rondslottet (2,178 m), Storronden (2,138 m), H�gronden (2,114 m), Midtronden western summit (2,060 m), Vinjeronden (2,044 m), Midtrondeneastern summit (2,042 m), Trolltinden (2,018 m), Storsmeden (2,016 m), Digerronden (2,015 m), and Veslesmeden (2,015 m).
In many parts of the park, there are spread-out holes (kettle holes) created by small remains of ice age glaciers, and peculiar small hills called "eskers" made by ground moraine released by melting glaciers
