Cape Arid National Park a vast 279,415 hectares, is located on the southeast coast of Western Australia, 120 kilometres east of Esperance.

Access to the park is from the sealed section of Fisheries Road. Nine kilometres of conventional drive all weather gravel road leads to park boundary. Another nine kilometres of the same quality roads lead to the main camp area at Thomas River. The majority of tracks within the park are rough four wheel drive and access is subject to weather conditions.

The park has magnificent coastal scenery, granite outcrops, swampy clay flats, several ruins and small mounts providing superb lookouts.

Vegetation in the park consists of young sand dune systems which support coastal heaths with patches of Yate, Banksia and Paperbark. Mallee stands, sometimes dense, occur, in the northern areas.

Diverse habitats within the park ensure a wide variety of fauna. Some of the more unusual species easily sighted include honey possums, brush tailed wallabies, cape barren geese, sea eagles and bustards.
