Bimberamala National Park contains steep forested ridges and gullies, intersected by the Bimberamala River. It includes areas of old-growth forest and six vegetation communities that are rare in the region or have a restricted distribution, including patches of temperate rainforest. Five threatened animal species have been recorded in the park.
Camp sites indicate that Aboriginal people utilised the resources of the area, probably travelling along the rivers and ridges. The southeast corner of the park and areas within adjacent State forests contain the remains of goldmining activities from the late 19th and early 20th centuries.
