Starting from the Gate 3 car park at the end of Richman Valley Road, Quorn, this walk takes you to the summit of Mount Brown and back via the Heysen Trail. Mount Brown is one of the tallest peaks in the South Flinders Ranges, standing at a height of 964 metres, named by Matthew Flinders after Scottish botanist Robert Brown, who climbed the mountain in 1802. This hike initially follows a fire track for a short distance past Waukarie Falls, then heads south along the Heysen Trail. The first few kilometres through the valley are fairly easy-going, followed by a relentless climb up a long ridge towards the summit of Mount Brown. At the summit, there's interpretive signage and a lookout tower commemorating Robert Brown, which offers panoramic views over the surrounding area, including Richman Valley, the Dutchman's Stern and Mount Remarkable. This hike consists of narrow walking trails, with very steep hills and some uneven rocky surfaces, suitable for moderate fitness levels. All junctions are clearly marked, with yellow distance markers and checkpoints with maps along the way, and there are usually printed brochures in the metal box at the trailhead. 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.
