Located inside Pat Sin Leng Country Park, Hok Tau Reservoir was once an area of streams and marshes with abundant water supply and therefore an irrigation reservoir was built there in 1968. For those who opt for doing things one step at a time, follow the left trail by strolling on a gentle uphill footpath; for those who likes to make haste, take the right route on what is famously known as the ‘68 steps’ in one go. Whichever route you take, you will be rewarded with vistas of the reservoir down the mountains at the top of Pat Sin Leng Country Park. Despite a capacity of 0.18 million cubic metres only, the reservoir is narrow and full of twists and turns. Skirting along the reservoir, the family walk features a picturesque bridge arching over running river. At certain heights, it offers an aerial view of the reservoir and the dam. Since the reservoir is located in the valley with plentiful water supply, it is home to many species of butterflies and dragonflies, including the rare Macromidia ellenae and the only freshwater fish species named after the territory Macropodus hongkongensis. There are barbecue sites and campsites around the family walk, making it an ideal place for families to get close to nature.
