A really nice loop walk in a corner of Berowra Valley Regional Park with good access by public transport. The walk starts and finishes at Thornleigh train station. The scenery includes beautiful scenes along Zig Zag creek and nice forest while going up Stringybark ridge plus as an optional side trip to see the remnants of the historic Thornleigh Quarry and Zig Zag railway. There are good spots to eat or grab a coffee near Thornleigh station before or after the walk.
