The experience is not good, and I only found out after I went there. The so-called Jiuyi Mountain is the collective name of the entire area, and the development of the scenic spot is rather chaotic. There is no unified plan or tour route. The scenic spots are far away, there are no commuter vehicles, and there is no road map for self-driving tours. So I personally think it's a pit.
Jiuyi Mountain is a very broad place, equivalent to a mountain system, not the name of a single mountain. Moreover, the scenic spots are scattered. If you don't have a self-driving car, I don't recommend you to visit it. To understand clearly, the most important thing is to do a good strategy.
