It's really dangerous to go up by bus. It's eighteen bends of mountain road. There are many tunnels, and it's also a bend tunnel. The maximum turning is 360 degrees. So it's very responsible for the driver to fasten his seat belt when he goes up the mountain. After getting off the bus and walking for more than an hour, it's still good to see the mountain scenery at the top. It's just that there are many people going to the glass trestle, especially in Garze, but it's worth standing in line for an hour, hanging in the air. If you are afraid of being upright, don't go. It takes less than an hour to get down. Generally speaking, it's worth playing.
