This section of the Great North Walk starts from Hornsby train station and winds down along the Blue Gum Walk into Fishponds and along Berowra Creek. The walk passes through the Tunks Ridge Reserve and then into Galston Gorge. From here the walk keeps following the Berowra Creek through the Crosslands campsite to Calna creek and then up to Mt Kuring-gai. 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.
