Paroo-Darling National Park is the big landscape excursion from White Cliffs. The park protects arid and semi-arid country, but the surprise is water: Peery Lake and the Paroo wetlands can draw serious birdlife when conditions are right.
This is remote-country travel, not a casual town park. Check road conditions before setting out, carry what you need, and be ready for the park to feel very different depending on recent rain.
