The Old Coach Link Trail is a challenging 5.8 kilometre hike (grade 4) located within Onkaparinga River National Park, South Australia. Designed for experienced walkers, the trail is estimated to take approximately 2.5 hours to complete.
Hikers can choose between two starting points in Old Noarlunga. The first option begins at Gate 1, situated near the former swingbridge location. The second option starts at Gate 3 on Church Hill Road, where you'll encounter a ford to cross the river.
The majority of the trail follows the Old Coach Road fire track. Be prepared for a steep ascent along the open grassy ridge towards the summit during the middle section. Nearing the top, the track branches off and follows the Pipeline Track and then the Tea Tree Track until reaching Gate 29 at the intersection of Sheoak Road and Barytes Road.
Planning for the return journey is crucial. Opting for a one-way (3.1km) hike requires prearranged transportation back to the starting point. To complete a return (6.2km) journey, simply retrace your steps along the same path. Hikers seeking a more extensive circuit route (refer to the map below) can follow the Pipeline Track north towards the Onkaparinga River. Upon reaching the river, turn westward (left) and follow the riverbank back to the trailhead at Gate 3 on Church Hill Road.
