Starting near the Old Noarlunga Uniting Church on Malpas Street, Old Noarlunga, this walk takes you on a circuit along the Onkaparinga River via the Pipeline Track and Old Coach Road. This hike crosses the bridge and climbs the grassy hill following the pipeline before descending steeply back to the river. Massive river gums and thick bush fill the valley, and the river is visible through the foliage. Keep a lookout for birds and other wildlife along the way. This hike includes one rock scramble and some narrow walking trails through overgrown sections. There is a short and challenging ascent about halfway through, followed by a steep descent. The rest of the walk undulates gently on well-formed tracks, and there is clear signage throughout. 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.
