When we went, the attractions seemed to be repairing, the pool at the door was drained, and there was an excavator under construction, but it did not affect the tour. After entering, take the boat first. A boat can take 8 people. The waterway is about 800 meters. Then it is followed by walking. There are many stalactites in the middle. There are several larger halls that will be charged for taking pictures. The three steps behind are also steep. I thought it would be very cold inside and wore a lot of clothes. It turned out to be a lot of sweat all the way down. The last exit seems to be on the mountain. It takes about half an hour to walk down the mountain. You can also take the slide. It is a small car like a roller coaster. A small car can take one person or 2 people. The fare is 45, but we have a counter-offer to 30 people. It is more fun. The attractions are generally good. There seems to be a bus at the door. If there is a joint discount ticket with a slide, it will be better to have a more favorable price.
