While you shouldn't expect rolling sand dunes, this arid park does cover a huge 1320 sq km and is rich in flora and fauna that thrive in the dry environment. There are over 670 indigenous plant species here, and in spring and early summer the landscape is transformed into a colourful wonderland of wildflowers. The best-known resident is the Malleefowl, an industrious bird that can be seen in an aviary at the Little Desert Nature Lodge.
The Nhill–Harrow Rd through the park is sealed and the road from Dimboola is gravel, but in the park the tracks are mostly sand and only suitable for 4WD vehicles or walking. Some are closed to 4WDs in the wet season (July to October).
