Subterranean river exploration, an immersive experience

Exploring the heart of the earth in extreme regions, a place worth recommending in summer, it's super cool inside and you can wear a coat. After ticket verification, you will be given a life jacket, a hat, and a flashlight. Then you get on a bus, and in about 5 minutes you arrive at the cave entrance, then walk to the underground river entrance to board the boat and start the tour. The first half has no lighting at all and is entirely illuminated by flashlights, giving it a very 'Tomb Raider Notes' feel. Along the way, the stalactites and naturally formed caves are very beautiful. There are also many bats flying around, and we even saw many small bats hanging upside down (sorry for disturbing your sleep). The boat ride takes about 1-1.5 hours, and the staff mentioned that the water is more than 20 meters deep in some places, and the river water is very cool. After the boat tour ends, you start walking, which also takes about an hour, and then you are back at the main entrance.
