Section 61 is an 18 km (11.2 mi) one-way point-to-point hike from Aroona Hut to the Parachilna Gorge Northern Trailhead, the Heysen Trail’s northern finish. It follows Aroona Valley to the watershed between the Aroona Valley and Parachilna Creek catchments, then continues through the valley between the ABC and Heysen ranges. The appeal is the long, changing walk and the satisfaction of finishing the Heysen Trail at its northern end. Allow about six hours, with five to seven hours a sensible window for pace and stops.
