The Centennial Grove Grotto and Walls Ledge Loop Track in New South Wales, Australia, offers a fantastic hiking experience. This moderately challenging 1.1-mile loop trail near Blackheath provides stunning views of the Magalong Valley below. As you walk along the cliff side, you’ll encounter beautiful rock formations and eventually reach the Centennial Pass1. The trail is popular for both hiking and walking, so you’ll likely encounter other outdoor enthusiasts. The Centennial Grove Grotto Canyon is a slot canyon with a small waterfall at the end. This waterfall drops into a pool where you can take a quick dip if the weather is warm. To get to that pool, you can walk through the water in the slot canyon or try to walk along a narrow-elevated path under a rock overhang.
