The Sundews River Gorge Circuit is a challenging 6km loop trail in Onkaparinga River National Park, South Australia. Expect to spend roughly 3 hours completing this exciting hike that combines the scenic Sundews Ridge Walk with a more adventurous trek along the Onkaparinga River gorge.
Your adventure begins at Sundews Carpark following the Gorge Link Track, which connects you to the well-maintained Nature Trail. This path leads you to the breathtaking Sundews Lookout, offering panoramic views of the surrounding area. From the lookout, descend via a contoured path until you reach the bottom of the gorge. Be prepared for some loose rocks and short sections that require rock scrambling.
Embrace the wild beauty of the gorge as you follow the river downstream for approximately 1.7km. The ascent back up utilises the steeper Gorge Link Track, leading you back to the trailhead.
Trail conditions can vary depending on recent rainfall. Higher water levels may make the river section more challenging. Always check the conditions before setting off. The circuit offers glimpses of the gorge throughout, with two permanent waterholes to refresh you along the way.
For easier navigation, tackle the circuit in a clockwise direction. This makes the fire trail exit at the end more readily identifiable.
