This trail is the longest nature trail in the country parks. With its undulating terrain and frequent ascents and descents, it is best suited to those with a reasonable level of fitness and some hiking experience. Shortly after setting off from the starting point, you will come across a bench crafted from upcycled old railway sleepers. Sleepers were originally used to hold rail tracks in position and maintain the correct gauge, preventing the rails from shifting as trains passed over them. After prolonged use, they become worn and must be replaced periodically to ensure safe railway operations. The MTR Corporation donated the retired sleepers to the Agriculture, Fisheries and Conservation Department for upcycling, giving them a second life as rest facilities in the country park. Continue for about 180 m to a junction. Turn left and descend a flight of steps to the Pak Kung Temple. In earlier times, villagers built three such temples along the main routes to Tin Fu Tsai Village, Tai Lam Village, and Kan Uk Tei, following the natural lie of the hills. The temples were built to pray for the safe passage of villagers as they travelled to and from the local markets. From here, walk on for about 400 m and enter a grove of Paper-bark Trees (Melaleuca cajuputi), their trunks peeling in pale, papery layers beneath a canopy of lush green foliage. After a further 400 m, you will reach the Tai Lam Forest Track — Tai Tong Section. Follow the directional sign for "Tai Lam Chung Reservoir" and continue for about 600 m, where Tai Lam Chung Reservoir and Kit Hing Bridge come into view. The waters here run swift and strong. In 1868, local residents pooled their resources to build Kit Hing Bridge, easing passage for those travelling through the area. Continue for about 350 m to a junction and follow the directional sign for "Tai Lam Nature Trail". After walking about 1.5 km, you will arrive at another junction, where the trails diverge toward Tsing Lung Tau and Castle Peak Road. Follow the direction for Tsing Lung Tau and walk for about 1 km to the Tai Lam Nature Trail Viewing Point, where you can overlook Tai Lam Chung Reservoir and gaze out toward Hong Kong International Airport and Tuen Mun. A further 450 m brings you to another viewing point. The vista here opens up, stretching across Deep Bay and Yuen Long, with the graceful span of the Tsing Ma Bridge reaching across the channel in the distance — a sweeping panorama where mountains meet the sea. Walk on for about 350 m to another junction, where the trails lead to Tin Fu Tsai and Tsing Lung Tau. Follow the direction for Tsing Lung Tau and continue for about 600 m to arrive at the Tai Lam Ecological Garden. The garden is home to a variety of plant species that attract an abundance of butterflies, making it an ideal spot to appreciate the richness of the local ecology. After your visit, follow the trail for a further 1 km until you reach a Tai Chi terrace, which marks the endpoint of this trail.
