Starting from the Mack Creek (Gate 4) car park on Humbug Scrub Road, Yattalunga, this walk takes you on a circuit around the Mack Creek sec­tion of Para Wirra Conservation Park via the Mack Creek Hike. This moderately challenging loop meanders around the Mack Creek section at the southern end of Para Wirra Conservation Park, passing through a variety of native bushland habitats. The walk initially follows the Mack Creek Bound­ary Track, parallel to Humbug Scrub Road, then continues alongside Bassnet Road. After crossing Mack Creek, the walk briefly follows Frank Barker Road along the park's southern boundary, then heads past the Orchid Dam. From there, the walk continues alongside Mack Creek, following the creek up­stream through a val­ley of mag­nif­i­cent riv­er red gums before returning to the car park. In late win­ter and spring, there are colour­ful displays of orchids along the trail. Walkers should note that this loop partially follows the Horseplay Trail, which is shared with horse riders. This loop consists of wide and narrow fire tracks and walking trails, with uneven natural surfaces, compacted natural surfaces, short steep hills and creek crossings, suitable for moderate 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.
