Completed in 1968, Plover Cove Reservoir is the second largest reservoir in Hong Kong in terms of the area it covers.  The many undulating slopes and the lack of supplies on this long hiking trail that skirts along the lake make it a test of experience and fitness.  Beginning along the ridge, the trail passes through such peaks as Ma Tau Fung, Chek Ma Tau, and Tai Tung.  The small plateau that links Wang Leng Au with Tai Tung is called Sam Toi Teng, which can lead the less physically-strong hikers to Ha Miu Tin to retrace their steps.  In fact, the ridge offers different sorts of scenery – on one side are the rich greenery of Plover Cove Country Park and the estuary of Sam A Wan; on the other side is the full view of Plover Cove Reservoir.  The latter part commands the view of Tolo Channel and leads to the auxiliary dam and the two-kilometre main dam.  As the world’s first reservoir in the ocean, Plover Cove Reservoir is undoubtedly an era-defining representation of creativity and courage – it is formed by connecting the island with land by the damming sections to dam the inlet, and pumping out the sea water and filling it with fresh water.  Along the way, hikers might be able to spot egrets and herons sitting on the floating solar power system, which is yet another social media check-in spot.
