The Serpentine Falls area often fills to capacity and is then closed to new visitors - plan to arrive before 10am. The scenic features of Serpentine National Park together with its close proximity to Perth have attracted visitors for almost 100 years. It is also a sanctuary for an array of plants and animals (particularly kangaroos) and has a shaded grassed area popular for picnics. Set in a naturally beautiful cleft at the foot of the scarp, the park stretched up the steep slopes if the Serpentine River valley, past a sheer face of granite polished smooth by the rushing waters. Past weathering has resulted in distinct landscapes of lateritic uplands, minor and major valleys and abrupt scarps.
