Section 6 of the Hong Kong Trail starts at Quarry Gap at an elevation of over 300 metres.  The towering trees by the sides of Mount Parker Road form a canopy of leaves that spreads all the way to the road, blocking out the sun and providing natural cooling, as if the path were air conditioned.  At the main dam of Tai Tam Upper Reservoir, the picture-postcard views of azure blue water and verdant hills come into sight, creating a sense of soothing tranquillity; the hundred-year-old main dam and masonry bridge, distinctive of Victorian architecture, are also worthy of appreciation – they are a feast for the eyes.
