The central feature of the region is Mount Kaputar, the park's namesake, which rises to an altitude of 1,510 m (4,954 ft).

[3] The 360 degree view from the summit of the mountain encompasses one-tenth of New South Wales' area or 80,000 square kilometres (31,000 sq mi).

[4] The park protects a wide range of biomes, including semi-arid woodland, subalpine heath, and eucalypt forests, and provides a habitat for a range of animals, including bats, birds, wallabies, quolls, and the unique red triangle slug (Triboniophorus graeffei) and pink slug (Triboniophorus sp.

[2] In 1925, some 775 ha (3 sq mi) of land around Mount Kaputar were declared a "Reserve for Public Recreation".
