Thornleigh to Cowan is a 35.9km, grade 4 One way hike located in Berowra Valley National Park New South Wales. The hike should take approximately 2 days to complete.


Following the Great North Walk and Berowra Creek through Berowra Valley Regional Park this walk cuts straight through the length of the Park. The views are good providing a broad idea of what this park has to offer. Conserve your energy for the section between Berowra Waters and Cowan as there are several solid hills. You can refill the tummy in Berowra Waters with a couple cafes to choose from. 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.
