The Sundews Ridge Hike is a moderately challenging 4.5km loop trail situated within Onkaparinga River National Park, South Australia. This scenic path offers hikers stunning views of the Onkaparinga Gorge without requiring a descent into the valley below. With an estimated completion time of 2 hours, the hike is perfect for those seeking a rewarding escape into nature.
The journey begins at the designated Sundews Carpark near Gate 11 on Piggott Range Road, where restrooms and trail information are available for your convenience. The well-marked trail leads you towards the Sundews Lookout, a vantage point offering breathtaking panoramas of the gorge's rocky outcrops and the meandering Onkaparinga River snaking through the bushland.
Here, the Sundews Ridge Hike diverges from the Lookout Hike. Continuing along the single-track path, you'll be treated to glimpses of the valley peeking through the trees. The trail includes a few short, manageable descents, making it suitable for moderately fit hikers.
As you emerge from the tree cover, a grassy section unfolds before you, revealing expansive views across the surrounding landscape. Take a moment to soak in the scenery and appreciate the beauty of the Onkaparinga Gorge. The return leg winds back into the trees before rejoining the wider Gorge Track. Keep your eyes peeled, as you might spot kangaroos or even a few sheep grazing peacefully in the nearby meadow.
The circuit hike concludes at the car park, marking the end of your exploration along the Sundews Ridge.
Looking to extend your walk? Enjoy the 6km Sundews River Gorge Circuit. This extended route descends into the heart of the gorge, offering a closer look at the river and its surrounds. Expect a more demanding hike (grade 4) taking roughly 3 hours to complete.
