Lau Shui Heung, a feast for the eyes and ears, certainly lives up to its name.  The start point Lau Shui Heung Reservoir, which is called ‘the Mirror of the Sky in the Forest’ among hikers, is a fairyland – in the morning it is cloaked in mist; on windless days upright Paperbark trees lined on the opposite shore are reflected in the water, with Lung Shan Bridge in the vicinity.  Built after the Second World War, this reservoir used to feed neighbouring farmland, but is now a hot spot for picnicking and taking photos at weekends.  This country trail is a circular trail, beginning and ending at the reservoir.  Despite some steep ascents in the latter part, the trail offers some recreational facilities like pavilions and barbecue sites, which makes the trip less difficult to complete.  To its northwest sits Kat Tsai Shan Au, which used to be filled with the pleasant scent of mandarin oranges given off by the rich crop of mandarin oranges prior to the Second World War.  The latter leg of the trail is Lung Shan, where a terraced campsite is located.  Word has it that before being renamed for auspicious reasons, Lung Shan was formerly known as Cheuk Shan.
