Located inside Tai Lam Country Park, Ho Pui Reservoir is an irrigation reservoir in Pat Heung, Yuen Long that feeds the fields in northwest New Territories. Compared to other large reservoirs, Ho Pui Reservoir bears a closer to a small lake in the mountains. When the water level is high, the submerged forests and the islets are like a gigantic sea turtle that has its emerald carapace emerged on the water surface. Apart from the gentle uphill slope before the entrance, the trail consists of level muddy paths that are easy to walk on. Towards the end is one of the very few S-shaped dams in Hong Kong. It sits nicely between artificial splendour and natural beauty, with a 17.4-metre outfall on one side and an oasis surrounded by water on the other. In the proximity to the family walk, there are campsites and organic farms, making it an ideal place for families to get close to nature.
