The park is situated in the Mid West region of Western Australia to the west of the Midlands Road between the towns of Badgingarra to the west and Dalwallinu to the east. The border of the park abuts Pinjarrega Nature Reserve to the north but is otherwise surrounded by farmland. Low Creek borders the park to the east, and then flows south to join Moore River.
The park is mostly composed of sand plain country which supports populations of heath, mallee and Banksia and many wildflowers. Eucalypt stands can be found to the western end of the park. Other species include the spinifex, wandoo and yorm gum. Some of the wildflowers found within the park include Kwongan, the bush cauliflower and the scarlet featherflower.
In 2010, the Environmental Protection Authority of Western Australia gave approval to survey the Warro gas field that is located beneath the park. The company Latent Petroleum was given permission to conduct a seismic survey, allowing them to drive over vegetation.
