In Sydney's far west, about 60km or so from the heart of Sydney’s CBD, Wallacia is an attractive semi-rural town on the banks of the Nepean River in the shadow of the Blue Mountains. Across the river to the town's west are two impressive features - one natural, the other man-made. Warragamba Dam, which plugs the end of the river of the same name, and the huge Blue Mountains National Park which covers some 1000sq km and has remained virtually untamed after tens of thousands of years of human habitation. The park, covered with tall eucalyptus forest with many waterfalls and shady glens, features spectacular gorges which are the result of erosion by the Grose River and Glenbrook Creek through more than 600m of colourful sandstones, shales and coals measures. Its forests also host the famous Wollemi pine - a living fossil that dates back to the age of the dinosaurs. Lookouts at Govetts Leap at Blackheath and Echo Point at Katoomba offer panoramic views, while there’s a great camping area at Euroke Clearing near Glenbrook. Back on flat land, water skiing is a favourite pastime on the broad reaches of the Nepean River near Wallacia.
