Rafting in a cave, underground canyon

This is one of the few 5A-level scenic spots in Shandong Province, China. It is a karst cave that was formed between 230 million and 65 million years ago. Of the total length of 6,100 meters, only about 3,100 meters are open to tourists. However, contrary to expectations, the cave itself is not a place with much to see. It is mainly a type of sports where you can ride a cave rafting or a more thrilling train. In particular, the train, such as the sky bike, must be operated manually and has a sense of speed, so it is secretly thrilling. However, since it is a bit disappointing to see this place alone, it is better to combine it with the nearby ‘Firefly Manual’. #China #Shandong Province #Yishui #Groundwater Canyon #Cave Rafting
