Ku-ring-gai Chase National Park lies at the place where the Hawkesbury River meets the sea: a tight cluster of secretive, winding creeks, sheltered beaches, hidden coves and wide expanses of deep blue water. Wildflowers grace the sandstone ridges, dense forests cling to the slopes, and mangroves squat on the tidal mudflats. This scenic beauty is combined with a rich Aboriginal heritage and a strong sense of history. So it's hardly surprising that millions of walkers, boaters, swimmers and picnickers have visited this icon Sydney park since it opened in 1894. Park highlights include: the rock engravings, hand stencils and other Aboriginal sites along the Resolute Track, historic Bobbin Head, with its picnic areas, marina and visitor centres, the outstanding water views from West Head Lookout or a day's outing on the ferry to The Basin, for a picnic and a swim around the lagoon or sandy beach.
