the gorge is also accessed on foot and via bike. the galston gorge east and galston gorge west climbs are both routes which are commonly taken by cyclists. the benowie walking track, the tunks trail and the ulolo trail are suitable bushwalking trails that run through the gorge. the most significant of these is the benowie walking track, which forms part of the great north walk that extends from sydney cove to newcastle. it is 25 km in length through berowra valley national park and can be accessed via six separate locations, generating a variety of different walks. the track is suitable for overnight walks, as the galston gorge campsite is located along the benowie walking track. although, this campground does not provide any water or facilities for campers. features such as the gulley creek falls, a small creek crossing, are also seen along the benowie walking track. the heritage bridges walk is an established bush-walk which begins at the constructed wetlands in clarinda street, hornsby, and follows predominantly fire trails with views of the two bridges before ending at the bottom of galston gorge.
