The Park features diverse vegetation and wildflowers which are particularly abundant during late spring and early summer.
The walk, which is 10.4 kilometres return, begins in the Cotton Tree Campground, Granya. The site of an old dairy, it has a gravelled parking area, large flat grassed area for camping, campfire pits and a long drop toilet. The track begins as a 4WD track leading up the hill towards the Scout Hut, an aptly named log hut constracted for the Granya Scout Group in 1937. The track then continues on to Granya Falls, which following rain are quite spectacular. From there, the path continues through open forest to the summit of Mount Granya.
Once at the summit, extend your walk by completing the Lyrebird Loop Nature Trail. This short walk (400m return) wanders around the summit of Mount Granya. Lyrebirds are often seen and heard.
Impressive summit views are to be had, particularly from the Georges Creek Lookout.
