The park consists of 5 non-contiguous parts. The majority of the park is a section of land north of Black Donald Lake surrounding Oakhill Lake and bordered on the east by the Black Donald Creek; another part is the largest island in Black Donald Lake, and the remaining 3 parts are portions of three smaller islets in the same lake.^[3][5]

The park protects unusual geological features and many rare plant species, including the Purple cliffbrake (Pellaea atropurpurea). It is a non-operating park, meaning there are no facilities or services.^[3]
