China has many sacred mountains, but they are not all the same kind of Buddhist travel experience. Some are pilgrimage islands filled with temples and incense. Some are real mountain hikes with Buddhist monasteries along the route. Others are famous not only for Buddhism, but also for martial arts, history and cultural symbolism.
For foreign visitors, four especially useful Buddhist mountain choices are Mount Putuo, Mount Emei, Mount Song with Shaolin Temple, and Mount Wutai. This guide compares what each one is best for, how difficult it is, how many days you need, what kind of Buddhist atmosphere to expect, and which one makes the most sense for a first trip.
This is still not a full list of every Buddhist mountain in China. Mount Jiuhua also matters greatly, but this page focuses first on the four destinations that are easiest to turn into a practical foreign-visitor itinerary.
