Lau Shui Heung Country Trail is a circular trail. Although it is shaded by trees along the way, it involves a total ascent of 300 meters, requiring a certain level of fitness. From the starting point, turn left and ascend the steps. After about 300 meters, you will reach a viewing point where visitors can take a break and enjoy the view of the Lau Shui Heung Irrigation Reservoir. Continue uphill for about 1 kilometer, then turn right towards Kau Lung Hang Shan and walk to the second intersection, which is the highest point of the route. Next, proceed to the southwestern end of the trail at Kat Tsai Shan Au. Although the fragrance of citrus can no longer be smelled today, this area was once filled with calamondin before World War II. Walking another kilometer along the trail will lead you past the Lau Shui Heung Campsite and Lung Shan Bridge. The sound of flowing water indicates you are near the Lau Shui Heung Irrigation Reservoir. Notice the small bridge on the left leading to the Bald Cypress thematic plantation area. The Lau Shui Heung Irrigation Reservoir is known as the "Sky Mirror in the Forest" by hiking enthusiasts. In the morning, it is enveloped in mist like a fairyland, and when there is no wind, it reflects a row of tall Paper-bark Tree on the opposite bank, creating a magical atmosphere! This enchanting reservoir was built after World War II to provide water for nearby farmland and has now become a popular hiking destination, with visitors often seen picnicking and taking photos on holidays.
