Starting from the car park near the cattle yards at the end of Wanganderry Road, High Range, this walk takes you to Bonnum Pic and back via the Bonnum Pic Walking Trail. This challenging walk ventures deep into Nattai National Park to Bonnum Pic, which lies near the end of a spectacular narrow ridge jutting out into the Wollondilly Valley. The walk initially heads along the Wanganderry Pass Fire Trail before following the signposted Bonnum Pic Walking Trail through dry eucalypt forest, then enters the Nattai Wilderness and follows an unmarked and overgrown trail to a cliff edge overlooking the Wollondilly Valley. From there, the walk heads north along the cliff line, passing over exposed dome-shaped rock formations, following rock cairns and pink tape markers. After passing a small camping cave and descending into a shady gully, the walk becomes more technical, requiring some boulder scrambling to reach Bonnum Pic, which offers panoramic views over the Wollondilly Valley, Lake Burragorang, the Wanganderry Walls and Mount Colong. Reaching the end of the ridge involves a dangerous scramble down an exposed rocky slope known as the 'slide of death', which requires a rope and should only be attempted by experienced bushwalkers. This walk consists of wide and narrow fire tracks and walking trails, with uneven natural surfaces, compacted natural surfaces, off-track sections, overgrown sections, rock scrambling sections, creek crossings and steep hills, suitable for high 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.
Warning This journey requires significant bushwalking experience, specialised equipment and navigation skills. Please ensure you and your group well prepared and equiped for this journey.
