There is an observation deck soon after the trail starts. The south of the observation deck overlooks Tsuen Wan and Stonecutters Bridge, while the north of it commands Ho Pui Irrigation Reservoir, which is encircled by forests. A small island in the middle of the calm water, Ho Pui Reservoir is the source of water for irrigation for the farmers in northwest New Territories. At the foot of the mountain is the scenery of the rural plains of Pat Heung, Shek Kong and Kam Tin. If you look closely, you will even see a mine cave at the roadside that is no longer used. With trees lining the trail, even summer is not stifling.  Spring brings yet another type of scenery - the blooming native Red Azalea will add redness to the mountain. Don’t forget the bluish and purplish flower, known as Skullcap, which may be right next to your foot though. A military general of the Han dynasty, Han Xin, allegedly used Skullcap to treat the soldiers. On the way, you will see Snake Strawberries, whose receptacles swell like balls and which look like strawberries. You will also see a type of plant called Dichrocephala integrifolia, its flower resembles eyeballs of goldfish.
