Introduction to Gaoba Feihong: Gaoba Feihong is located at the entrance of Tonglingshan Gorge. The lake covers an area of ​​about 4 square kilometers and the water is green. The dam is 80 meters high. When the spill gate is opened, a curtain of water more than 20 meters wide rushes down, like a sea of ​​clouds pouring down, and thousands of horses galloping, shaking the canyon; under the sun, a hundred rainbows hang in the sky, which is extremely spectacular.
