Pak Tam Chung (北潭涌) is the start of the MacLehose Trail. While you’re in Pak Tam Chung, visit the Sai Kung Country Park Visitor Centre, which is to the south of the village, just by the road from Sai Kung. It has excellent maps, photographs and displays of the area’s geology, fauna and flora, as well as useful information on the traditional villages nearby and Hoi Ha Wan Marine Park.
