Just about a 20 minute drive from the city is Lane Cove National Park. Here you will find a 6.8 mile running track following the shores of Land Cove River. Start in Chatswood Park (where there is parking available). Catch the Riverside Walk trail and enjoy the gnarled red gum trees and rocky outcroppings. Cross over the De Burghs Bridge to return along the opposite bank. Along the way, look for caves and Australian native birds including kookaburras (with a laughing-cackling call) and lorikeets .
