Introduction to Guanshan Canyon: It is about one kilometer long, more than ten meters wide, and up to one hundred meters deep. The route is extremely dangerous and lined with huge boulders. The rock walls on both sides are like knives and axes. There is virgin secondary forest here, and you can take an outdoor trip through the canyon with your bare hands. The process of crossing is thrilling. Sometimes you have to wade across the pond and sometimes pass through the cave. Relying only on simple iron-locked plank roads and other tools to climb over the dangerous passes, if you are not careful, you will come into close contact with the stream and have a passionate kiss with the stone, which will test the physical fitness and will of the tourists.
