Starting from the Hardys Scrub (Gate 16) car park on Chapel Hill Road, Blewitt Springs, this walk takes you on a circuit around the eastern end of Onkaparinga River National Park via the Hardys Scrub Hike. This moderately challenging loop meanders through a large area of remnant native veg­e­ta­tion in the southeastern corner of Onkaparinga River National Park, with a rich diver­si­ty of plants due to its var­ied soils. The area conserves an important patch of grey box wood­land, which was once widespread in this part of the Adelaide Hills but has been mostly cleared for housing and farmland. Pink gums and southern cypress pines are also found here, and during late winter and spring, there are colour­ful displays of orchids and wildflowers. This is one of the only walks in the park that doesn't take in the river or gorge. There are picnic tables along the trail, as well as several alternative route options. This walk consists of wide and narrow, gently undulating walking trails and fire tracks, with uneven natural surfaces and compacted natural surfaces, 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.
