Ancient trails used to be a key route for villagers to communicate and do trade with the outside world in the old days.  Many of them, including Nam Hang Pai Ancient Trail, Kap Lung Ancient Trail, and Yuen Tsuen Ancient Trail, lie inside Tai Lam Country Park, which also has the greatest number of country trails.  Linking Yuen Long with Tsuen Wan, Yuen Tsuen Ancient Trail has witnessed the time when villagers of Shap Pat Heung transported farm produce to Tsuen Wan Market.  The country trail also passes through the 400-metre Shek Lung Kung, which enjoys a 180-degree panorama of Tsing Yi, Rambler Channel, Ting Kau Bridge, Tsing Ma Bridge, and Lantau Island.  Tsing Ma Bridge, which opened in 1997, stretches for 1.377 kilometres, crossing Ma Wan Channel.  As one of Hong Kong’s architectural landmarks, the bridge was the world’s longest suspension bridge carrying road and rail traffic. The junction of the trail and Section Nine of the MacLehose Trail is Tin Fu Tsai Campsite, which was a resting point for commuters in days gone by.  Further along the shaded path is Kat Hing Bridge, which connects to the Sweet Gum Woods in Tai Tong, the finishing point of the trail.  In winter, the red leaves on the lines of Sweet Gum Woods in Tai Tong make for a great photography spot and give some welcome shade from the sun.
