The Ayi River Canyon sightseeing lane is 14 kilometers long and built close to the mountain wall. It sometimes passes through mountains and winds along cliffs, with sharp bends and dangerous roads that only allow one car to pass in one direction. By taking a sightseeing bus, you can enjoy the thrilling scene of the raft "Wave Suppressing Flying Boats" in the valley, as well as the peaceful scenery of green mountains and swaying bamboo on both sides. The sound of flowing water and the melodious chirping of birds by my ear, along the way, I arrived at the exit leisurely.
