The underground Grand Canyon belongs to the national 4A-level scenic spot. The parking lot inside is large, the scenic spot is very clean, and the service is great. Tourists with children and the elderly can take the sightseeing car in the park for 10 yuan per person to reach the hole directly. Other affiliated charges such as Xiaofeilong, Adventure Island, The zipline personally feels really meaningless, that is, it is to spend money in vain. The main underground part is really amazing. I sigh the ghostly work of nature and appreciate the essence of the main attractions. The scenery on the ground is very general. There is no need to waste money!
