Hornsby Heights and Crosslands loop walk
This newly-surveyed circuit links a series of Hornsby Heights fire trails and streets, the Great North Walk, the Crosslands Reserve, and the Lyrebird Gulley track. It's done with the help of two short off-track bits, which involve some steep scrambling in possibly damp and slippery creek beds. You'll need to be comfortable with this sort of thing. It's all very scenic. Car pooling from Hornsby station.
