Wutong Mountain National Park (梧桐山Wutong Village Luohu District 罗湖区捂桐村). At just over 900-m tall, Wutong Mountain is the second tallest mountain in the Pearl River Delta after Hong Kong's Tai Mo Shan and it is a Mecca for hikers and climbers. This has been a recognised beauty spot since at least the Ming Dynasty when it was included in the Eight Great Views of Xin'an County and was celebrated in poetry. There are several routes to the top varying significantly in difficulty. The broad road will be a gentle climb. But be prepared for a good 5 hours if you intend to go to the top and back. There are two peaks, Lesser Wutong where the Shenzhen TV Company has its handsome transmission tower, and Greater Wutong which is reached via the notoriously difficult Hao Han Slope. On a clear day, the views from the summit over Mirs Bay and the mountains of Hong Kong's New Territories are indescribably beautiful. Night views over the city set against the sweep of Shenzhen Bay are also to die for.
