Grassy Hill, Mountain summit in Tsuen Wan District, Hong Kong.
Grassy Hill is a mountain summit in Hong Kong, sitting at the boundary of Tsuen Wan, Tai Po, and Sha Tin districts, at about 647 meters (2,120 feet) above sea level. The terrain is largely open near the top, with rocky ground and low vegetation, giving way to denser forest on the lower slopes.
Grassy Hill formed during the Late Jurassic period, roughly 160 million years ago, through volcanic activity. The volcanic rocks and tuffs that make up the mountain are part of a broader geological story shared by much of Hong Kong's terrain.
The MacLehose Trail, a long hiking route that crosses Hong Kong from east to west, passes close to the peak and draws local walking groups on weekends. The area is a natural retreat for city residents who come here regularly to walk and spend time outdoors.
Trails approach the summit from several directions, so it is worth checking a map before setting out to choose the best route for your level. Weather in Hong Kong can change quickly, especially in summer, so starting early and bringing water is a good habit.
Grassy Hill sits within the catchment area of Shing Mun Reservoir, meaning that rainwater falling on its slopes feeds into one of Hong Kong's main water sources. Most people who walk to the top are unaware of this connection between the mountain and the city's water supply.
