Hard track
This overnight walk starts from Thornleigh train station and follows the Great North Walk down through the Berowra Valley Regional Park and along Berowra creek. The walk passes through Fishponds and up to the top of Galston Gorge to the campsite. From there, the walk continues along the Great North Walk, down through the gorge and along Berowra Creek to Crosslands Reserve, then back out the well signposted Mt Kuring-gai link track. The walk finishes at the train station, soon after leaving the bush. Note this walk was re-routed in early 2016 to go via the streets of Hornsby Heights. This re-route is due to the multi-agency decision to close the Fishponds to Steele Bridge section of the Benowie Track. This decision has upset many people and the protest continues.
