The parks contain rolling and steep forested hills, providing known habitat for 14 threatened animal species, including the koala, yellow-bellied glider, squirrel glider and three species of large forest owl. They are also part of an important wildlife corridor that, together with areas of state forest and other lands, links the coastal reserves of Maria National Park, Hat Head National Park and Limeburners Creek Nature Reserve in the east with Willi Willi National Park in the west.
Kumbatine National Park and Kumbatine State Conservation Area contain a number of Aboriginal sites, including open camp sites and scarred trees, while Kumbatine National Park also contains convict lime kilns that are listed as items of state and national significance.
Both parks are used for a range of recreational activities, including bushwalking, horse riding and car touring.
