[1] A precinct of Western Sydney Parklands, and situated within the heart of the Cumberland Plain Woodland, the regional park features several picnic areas, recreational facilities, equestrian trails, and walking paths within the Australian bush.

The regional park rises as one moves to the west of it, with the elevation reaching 140 metres (460 ft) at its highest point.

[8] Western Sydney Regional Park features around 135 hectares of developed natural woodland communities where the bulk of the regional park constitutes 427 hectares of planted revegetation and cleared grassland environments, thus providing multifarious habitat areas for wildlife and vegetation communities.

The understorey plants usually rely on underground tubers or abundant annual seed production to survive untoward conditions.

Apportioned shrubs include Bursaria spinosa, Solanum prinophyllum, Rubus parvifolius, Breynia oblongifolia, Ozothamnus diosmifolius, Hymenanthera dentata, Acacia floribunda and Phyllanthus gunnii.

The groundcover in the river flat areas mainly consist of forbs, scramblers and grasses including Microlaena stipoides, Dichondra repens, Glycine clandestina, Oplismenus aemulus, Desmodium gunnii, Pratia purpurascens, Entolasia marginata, Oxalis perennans and Veronica plebeia.

[1] The Western Sydney Dry Rainforest, which is to the west of the park, features Melaleuca styphelioides, Acacia implexa and Alectryon subcinereus.

[1] Invasive plant species include, Araujia sericifera, Cardiospermum grandiflorum, Asparagus asparagoides, Rubus ulmifolius, Cestrum parqui, Lantana camara, Olea europaea subsp.

Western Sydney Regional Park contains Calmsley Hill Farm, which is protected under State Heritage listing.

The park features a broad system of walking and cycling opportunities on various tracks which link the several fundamental recreational areas.

There exists a walking track called the Spotted Gum Trail, which is 3 km in length, that loops around Plough and Harrow within the native bushland, thereby allowing walkers to encounter kangaroos and wallabies, in addition to birdwatching.
