Wawu mountain is located in the “rain screen in West China” area with the most intensive rainfall in China. The well protected primeval forest on the top of the mountain and the huge platform on the top of the mountain form a natural water culvert area, and many springs form multiple waterfalls with a drop of more than 400 meters. The vast primeval forests and waterfalls make the negative oxygen ion content as high as 25000/cubic centimeter, and the average temperature in summer is about 16 ℃.
