Starting from the Gate 11 car park on Piggott Range Road, Onkaparinga Hills, this walk takes you on a circuit around Onkaparinga River National Park via the Nature Trail, Echidna Trail, Bakers Gully Track and Sundews Ridge Hike. This challenging hike combines several trails in the eastern end of Onkaparinga National Park, with spectacular views over the narrow river valley of Onkaparinga Gorge. The loop was designed to stay on the same side of the river, which is often difficult to cross. The park protects some of the finest remnant vegetation in the region, providing habitat for native wildlife such as birds, koalas, kangaroos, possums and echidnas. The hike initially follows the Nature Trail through regenerating pink gum and grey box woodlands, then heads along the Echidna Trail, passing the ruins of an old cottage and a side trip to a seasonal waterfall. The hike continues along the Bakers Gully Track, descending to the river before returning along the Nature and Echidna trails, then follows the Sundews Ridge Hike past the Sundews Lookout, which offers great views over the river. This loop consists of fire tracks and narrow walking trails, with some short steep hills and creek crossings, suitable for average 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.
