Introduction to Buyun Bridge: After tourists leave the Mysterious Valley, they can see a bridge spanning the canyon, connecting the two cliffs into one, as if walking on the clouds. At an altitude of 900 meters, it is the highest iron cable wooden bridge in Tianjin. This bridge also means that although the mountains and roads here are high and dangerous, visitors will be influenced by the aura of the top of the mountain and will have a bright future.
