About 10.1 kilometers from the trailhead, Huangma Suspension Bridge No. 2 is exquisite and quietly sits across smaller creeks. The water supply is no abundant, but the small stream cuts through the earth, showing how great the sheer force of running water is. Huadong Valley is located in the area with active tectonics which provides great geological stresses. Plates are pushed up, which accelerate the downward erosion of creeks, forming a landscape of the secluded deep valley.
