Thornleigh to Galston Gorge is a 15.5km, grade 4 One way hike located in Berowra Valley National Park New South Wales. The hike should take approximately 6 hrs to complete.


This walk follows the Great North Walk above Berowra Creek from Thornleigh to Galston Gorge on bush tracks and service trails. The Steele Bridge is quite an interesting landmark of the area. Fishponds is a wonderful highlight it is a lovely water hole surrounded by tall sandstone cliffs. The walk finishes on a road a long way from anywhere you will need to organise a friend to pick you up. 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.
