To enjoy the scenic beauty of Yuen Long, the best way is to walk in the mountains.  Tai Lam Chung Country Trail begins at Ma On Kong Warden Post, which is in close vicinity of Tai Lam Tunnel.  Views open up after series of ascending stairs of the 290-metre country trail, offering the scenery of mountains and water of Yuen Long Plain, Kam Tin, Shap Pat Heung, Tin Shui Wai and Tuen Mun.  The trail also amazes hikers with slopes that have been eroded by rainwater.  The real reward comes after scaling several mountains, when it reaches the finishing point Kat Hing Bridge, which was built more than a hundred years ago.  Given the fast-flowing stream of Chat To River, the bridge was built in the Qing Dynasty to make crossing easier.  The bridge was renovated in the 1950s during the construction of Tai Lam Chung Reservoir.  It is an excellent spot to muse on memories of ancient times, appreciate the beautiful scene of how streams merge together, or even revive the happy memories of walking on Tai Lam Chung Country Trail.
