The park was established on July 5 1996, but has managed consistent with a statutory plan of management which was adopted in 2003.
The park features waterfalls that plunge from the plateau on the edge of the Warrumbungle and Liverpool ranges (which are all essentially part of the Great Dividing Range.
It is home to one of the largest populations of greater gliders in Australia, but is also home to numerous eucalyptus and pine trees as well. Also contains giant grass trees and open forest with stands of snow gums shelter gliders, wallabies, eagles and owls.
Generally the park is cold during the winter, but warm during the summer and rainy during late summer to autumn. Usually, the best times to visit the park are between spring to summer for more general things to do here, but late autumn after the rainy season if you wanted to camp here.
The only way to get to Coolah Tops National Park is by car. From Coolah, head east for 19km Coolah Creek Road, and then use The Tops Road for 11km before entering the park. Do note that The Tops Road is not paved, but the quality of the road is like any other road crossing the Great Dividing Range.
