Starting from the Sundews Trails (Gate 11) car park on Piggott Range Road, Onkaparinga Hills, this walk takes you on a circuit through Onkaparinga Gorge via the Onkaparinga Gorge Hike. This challenging loop explores the spectacular Onkaparinga Gorge at the eastern end of Onkaparinga River National Park, which has the most intact native vegetation in the park. The trail initially winds its way through native vegetation before reaching the Sun­dews Look­out, which offers scenic views of the rocky outcrops and the gorge below. From there, the walk descends steeply to the bot­tom of the gorge and follows the riv­er down­stream, passing several scenic waterholes, then follows a steep fire track to the top of the ridge and back to the car park. The trail isn't well-defined along the river and involves some rock scrambling. The descent and ascent in and out of the gorge are steep and may be slippery after rains, and the river is often impassable during wet periods. This loop consists of wide and narrow fire tracks and walking trails, with uneven natural surfaces, compacted natural surfaces, steep hills and rock scrambling sections, suitable for high fitness levels. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
