The Baden Park Rest Area is 173km from Cobar and 87km from Wilcannia. The rest area contains a sheltered picnic area and amenities (known as Windyloo). There is lots of space for parking, some with shade. I could not find any signs prohibition overnight camping. However, if you do decide to stay here overnight you do so at your own risk.
