A rocky, reptilianlike spine runs through the center of Hong Kong Island, and there are some 30 miles of hiking trails spreading over it like arteries, offering visitors exercise along with excellent sightseeing. One of the most popular sections is the three-mile Dragon’s Back trek that follows the undulating ridge on the southern end of Hong Kong Island, between Wan Cham Shan and Shek O Peak. The walk isn’t strenuous, but the views may take your breath away. All along the way, soak up panoramas of the island and the sea. The entrance to the hike is on Shek O Road near To Tei Wan village, and the trek should take about 4-5 hours.
