Yes, it is difficult, but Pat Sin Leng, which is part of the Wilson Trail, is one of the most rewarding and scenic hikes you can take in Hong Kong. The name refers to the Eight Immortals of Chinese folklore, and this trail threads up and down across the top of the eight peaks. With the highest summit at 600 metres, you are guaranteed spectacular views of the surrounding country park, and a sense of accomplishment. Start your walk from the mini bus stop at Hok Tau Wai village.
