Shing Mun Reservoir was built in 1937. Its main dam, steel bridge, valve tower and bellmouth overflow have been graded as Grade I historic buildings, making the reservoir one of the most popular hiking spots among Hongkongers. Over one hundred types of butterflies were recorded within the country park; the paperbark trees that surround the reservoir are even favourite check-in spots. The reservoir leads to Needle Hill, which allegedly means a mountain with a pointed crest in the Hakka dialect.  Despite only having the altitude of 532 metres, Needle Hill, as shown by its name in the Hakka dialect, is exceedingly steep. As a Chinese saying goes, “You would never appreciate the pain if you did not go through it”. Only when you experience it could you understand the experience per se. To scale Needle Hill, you have to climb over a thousand steps within 1.7 kilometres, which, together with sparse trees, puts endurance and willpower through the mill. However, the scenery that one can see on Needle Hill is well worth the efforts. After climbing up to the crest, you will be rewarded with the panoramic view of Shatin in front of you and, if you navigate your way through the narrow and mighty reservoir, you will then be rewarded with the view of Kwai Chung, Tsing Yi and Tseun Wan. If you scale Grassy Hill, which has an altitude of 647 metres, you can enjoy an even wider view ― this is what the hikers call Needle Hill, Grassy Hill and Tai Mo Shan face one another. Never will you get bored with the spectacular views on the way to the end point ― Lead Mine Pass.
