Corbett National Park comprises 520.8 km2 (201.1 sq. mi) area of hills, riverine belts, marshy depressions, grasslands and a large lake. The elevation ranges from 1,300 to 4,000 ft (400 to 1,220 m). The park has sub-Himalayan belt geographical and ecological characteristics. Dense moist deciduous forest mainly consists of sal, haldu, peepal, rohini and mango trees. The rich biodiversity of the Reserve is partly attributed to the variety of habitat found here. Due to the location of the Reserve in the foothills of the Central Himalayas, both Himalayan and peninsular flora and fauna is found in the Reserve.
