Huangshi Grand Canyon is one of the famous landscapes in Huangshi Park. It can also enjoy the magnificent scenery of the canyon and the waterfalls flowing down. The Yellow Stone River, 97 kilometers long, is the only river in the United States without dams. The river runs through the volcanic rocks and has been eroded strongly for a long time, forming a magnificent Yellowstone Canyon with a length of 32 kilometers, a width of 450-1200 meters and a depth of 360 meters. This is the most magnificent and beautiful scenery of Yellowstone Park. Long-term river erosion has formed a magnificent rock wall, showing yellow, orange, brown, brown, etc., Indians call it "Yellowstone" - - Yellow Stone thus named. From the Huangshi River to the Huangshi Canyon, it falls twice in less than one kilometer, forming two waterfalls. The downfall is 92 meters high and is the most ornamental Canyon waterfall in Yellowstone Park. It is nearly twice as high as the world-famous Niagara Falls and 33 meters high as the Upper Falls. On the other side of the Huangshi River, there are sightseeing spots, in turn - "Lookout Point, Grand View and Inspiration Point. The best viewing point of the Huangshi Grand Canyon is Inspiration Point. It should be noted that this road is a one-way street, and the convenience before leaving this road is Canyon Village. In Upper Falls, the Yellowstone Canyon feels like an oil painting. But you can only see the waterfall from a distance. Then we go Uncle Tom" s Trail. Back from the Artist Point viewing terrace along South Rim Drive, the southern edge lane, and back to the main road, there is a fork, you can go to Uncle Tom ''s Trail, close to Lower falls. Although the full length is only about 2 miles, the steel staircase in the second half is steep, a total of 328 steps, down about 20 minutes, it takes 40 minutes to walk up. I thought I could go down to the bottom of the waterfall, but I actually went down to the waist. But it's close to the waterfall. It's still spectacular. As long as the weather is good, you can see a rainbow across the canyon.
