Fodor's Expert Review Kings Canyon

Inside Watarrka National Park, Kings Canyon is one of the most spectacular sights in central Australia. Sprawling in scope, the canyon's sheer cliff walls shelter a world of ferns and woodlands, permanent springs, and rock pools. The main path is the 6-km (4-mile) Kings Canyon Rim Walk, which starts with a short but steep 15-minute climb straight up from the parking lot to the top of the escarpment; the view 886 feet down to the base of the canyon is amazing. Steep stairs mark your arrival into the scenic Garden of Eden—the only way out along the main trail is via another round of intense stair-climbing back up to the top of the canyon wall, so make sure you're carrying plenty of water for the hike. An easier walk, called the Creek Walk, which starts at the parking lot and winds through the base of the canyon, is just as worthwhile. Alternatively, Kings Canyon Resort offers 8-, 15-, and 30-minute helicopter rides so you can view it all from above (from A$95, A$150, and A$285, respectively).
