Xianqi Cave is located in Dongguanshang Village, Zhangfang Township, Fangshan District, Beijing. It is rather unique cave compared to others. What makes it different is that when the ferryman is pulling the towrope in the middle of the mountain along the 500 meters water route, with a view to getting into the cave, sitting in the boat and feeling the gentle touch of the breeze, you will experience the fantastic feeling brought by the unique landscape. So it is also called “Beijing's paradise on earth.” Some entrances of the caves are very narrow, while others are quite wide. The paths inside the caves twist and turn, and the stalactites in the cave are generally formed about 300,000 to 700,000 years ago according to some relevant experts.

Yinhu (literally meaning Silver Fox) Cave is 60km away from downtown Beijing. The characteristic attraction is the snow-white calcite crystal which is nearly 2 meters long and resembles a cat-headed fox hanging on the top. It is called "Chinese National Treasure" - Silver Fox.

Developed more than 400 million years ago in the Ordovician limestone, the cave space was formed within millions of years. The entrance of the cave is 207 meters above sea level and 10 meters in relative height. It is called "The Underground Labyrinth of North China".

The annual temperature of the Yinhu Cave keeps at around 14 to 16 °C, and long sleeves are recommended when going in summer. The 530-meter tunnel in the cave is equipped with trams, which can be used without an extra ticket.

Yinhu Cave is worth visiting for two reasons: First, the rare stone chrysanthemum, crystal flower, stone pearl, stone grape and other landscapes can be seen everywhere in the cave. The most fabulous is the large fox-like calcite crystal with a length of nearly two meters. The crystal full of white and clear plush and seta is first discovered for the world's caves.

The second is that at the bottom of the Yinhu Cave, there is a deep underground river 106 meters down from the entrance. The water in the river is crystal clear. It has become natural magnetized water after flowing through the magnet deposit, and has obvious anti-inflammatory and bactericidal functions.
