Situated in the valley, floodplain and reclaimed land, Tsuen Wan is surrounded on two sides by hills and woodlands that make up the Shing Mun Country Park and the Tai Mo Shan Country Park. Located within these parks are the Tai Mo Shan peak, the highest point in Hong Kong at 957 metres (3140 feet), and the Upper Shing Mun Reservoir. Route Twisk winds over and through the country parks linking Tsuen Wan with Pat Heung, via Shek Kong. Originally built by the Royal Engineers as a military road, it was opened to the public on 25 May 1961.
