Zhijin Cave

The Zhijin Cave is like a vast underground palace, complete with a velvety moss around the first reception hall cave and sparking rare rock formations throughout. It is also China's largest, around 173 m wide and 150 m tall at the cavern's largest point. Visitors are taken past a dense forest of glistening stalactites and stalagmites deep under the surrounding hills; the whole tunnel and cavern complex is over 12 km in length. There's a superb array of different karst formations, including one large and particularly unique example in the main cavern. It has unusually shaped passages and grottos, which you explore in semi darkness, down the paths created by felled stalagmites. Guizhou province is worth visiting for its misty terrain of high altitude plateaus and craggy peaks. While walking on the province's quiet tracks you'll also come across some of China's most remote and traditional villages. China's highest waterfall, the Huangguoshu Fall, is nearby.
