The southern and western sides of the park form the steep slope of the Western Ghats ridgeline, with the altitude varying from 100 m - 1892 m (peak). The northern, central and the eastern portions of the park constitute a chain of rolling hills with a mosaic of natural grassland and shola forests. Kudremukh receives an average annual rainfall of 7000 mm, largely due to the forest types of mainly evergreen vegetation that can be found here.
