The MacLehose Trail (Chinese: 麥理浩徑) is a 100-kilometre hiking trail that crosses much of the New Territories, Hong Kong, starting from Pak Tam Chung, Sai Kung, in the east to Tuen Mun in the west. The path is marked by distance posts at 500-metre intervals. The trail is named after Sir Murray MacLehose, the longest-serving governor of Hong Kong, who established the Country Parks and was himself an enthusiastic hiker. The trail passes through a variety of natural scenery including beaches and mountains. (From Wikipedia)
This series of 5 caches is placed along section 10 of the trial starting from Tuen Mun.
