The main tourist destination is Huangshan (Yellow Mountain). From the Yuping Cable Car/Mercy Light Temple entrance, the "Western Steps" lead up for about 14 km over spectacular terrain. Allow 6-7 hours for the ascent. If you are fit and have a good head for heights, the steep ascent to Celestial Capital Peak is rewarding. From the Yungu Cable Car parking lot, the ascent by the "Eastern Steps" is easier, taking as little as 2-3 hours. If you choose to descend by the Eastern Steps you can extend the hike by including the Nine Dragon Waterfall area (Jiulongpu) for an additional charge.
The paths are all stone steps that can make your legs rubbery after a while. Remember: a long descent is not that much easier than an ascent. Huangshan is most famous for its sun rise and sea of cloud at dawn. However, all these wonders are subject to weather conditions. In the off-season, Mount Huangshan can be extremely foggy in the morning. Approach your hotel or hostel counters for some travel tips in this area; they are typically very experienced locals.
