Extra fees for the Stone Flower Cave?

Other than the admission fee, you do not need to pay extra fee for entering the cave. The whole cave can be finished visiting in about an hour and half with the help of the tourist guide. All the tourists there will be guided. Including the transportation, one day is enough.

But how is it possible to fit "twelve huge "halls" which are interconnected with countless narrow passages, sixteen "chambers" and 71 "branch caves" in many sizes and shapes" and "the Silver Fox Cave is worth visiting. It was discovered and developed in 1991. Composed of eight halls and over 40 scenic sights" all in one and a half hour? Can we tour the caves ourselves, rather than getting a guided tour?

They are naturally formed by the nature force. The whole place can be finished visiting in about an hour and a half by tour guide. If you want to travel alone, you may need more time.
Actually, the tour guide is provided by the scenic spot and it is better to travel with the guide, so that you can enjoy the beauty well.
From the Stone Flower Cave to Silver Fox Cave, it is suggested to take a taxi at the gate for you, because there is still a long distance between them and it may be a little difficult for you to find the exact place.
