This great walk starts from Crosslands Reserve. The walk follows a section of the Great North Walk along an old road timber boardwalk and firm dirt tracks to a lovely timber lookout platform on the edge of Berowra Creek. Along the way are signs providing interesting information about the mangroves estuaries and other surrounding flora and fauna. Make a day of it by enjoying the picnic areas and playground at the start of the walk. You can even book a campsite and enjoy the area for longer.
