The Ayi River Canyon sightseeing lane is 13 kilometers long. It is built against the mountain, sometimes chiseling through the mountain, sometimes walking along the mountain, with sharp bends and narrow roads, only allowing one car to pass through. Riding on the sightseeing bus, you can enjoy the thrilling and exciting scenery of "waves restraining flying boats" in the river valley, as well as the leisurely and leisurely scenery of green mountains and lush bamboo on both sides. Listening to the sound of flowing water and bird songs, you can leisurely reach the exit.
