Featuring undulating mountains with a steep gradient, the third section of the MacLehose Trail is definitely one of the top three in terms of difficulty. Surrounded by Ngam Tau Shan, Wa Mei Shan, Lui Ta Shek and Kai Kun Shan, their dazzling heights at around 400 metres above sea level can also offer you distinct appearances of the rolling mountains from different angles. Terraced fields can even be seen in the depths of the forest. Climbing from Pak Tam Au, the start point, up to Ngau Yee Shek Shan is a radical challenge of the third section of the MacLehose Trail. Every one of the stone steps, which are about one kilometre long, puts your perseverance through the mill, and if you successfully navigate your way to the crest of the mountain, you will be rewarded with an unobstructed view up there - Kei Ling Ha Hoi to the east, Tolo Harbour to the north, Tai Po to the west, Ma On Shan to the south. After a break on the crest of Cheung Sheung, proceed to Kai Kung Shan, and if you are determined to plough on, rest, food and water are crucial.
