This is not a tourist destination, this is a location for experienced cavers with proper equipment. I went there on a private taxi tour to Ganjia and was not prepared for entering the cave. I was guided by a monk who had a flashlight while I had none. It was pitch black so he'd move forward a little and then shine the light so I could see my footing. There are 20m+ falls and little to no safety fences or steps and in parts you make your way down on rusty old ladders. The cost was 39 rmb to visit the cave and nearby monastery. The cave itself is extensive, apparently you could explore it or hours but I would only recommend this to experts.
