Nambung National Park
Imagine an eerie moonscape where pale yellow limestone formations loom as high as 15 feet. Now see the image in your head displayed before you at Nambung National Park, set on the Swan coastal plain 200 km (125 miles) north of Perth, along the scenic Indian Ocean Drive. At the park you can walk among those otherworldly formations in the Pinnacles Desert, home to one of the world's most spectacular karst landscapes. Geologists believe the pinnacles were created by the dissolving action of water on exposed limestone beds that formed under wind-blown sand dunes. Only a tiny proportion of them have been uncovered. The 1.2-km (0.7-mile) return walk starts at the parking area. There's also a 4-km (2½-mile) one-way Pinnacles Desert Loop scenic drive (not suitable for large RVs or buses). Stop in to the Pinnacles Desert Discovery Centre to see interpretative displays focused on the region's unique geology, flora, and fauna. August through October the heath blazes with wildflowers. Note the rules: no pinnacle climbing, no dogs, no littering (no receptacles are provided, so take your trash with you), and no camping. There is no drinking water available throughout the park, although water is available to purchase at the interpretative center and gift shop.
Indian Ocean Drive is a frequent crash zone; please take care and avoid driving at dawn, dusk, and dark.
