It feels good, the underground Grand Canyon is very magical, and the rafting is also very fun, but the rafting needs to go in and buy tickets later. It feels good to come to play in May and June later. Now the firefly water hole doesn't feel much, but it's also very interesting.

The scenic spot is not big. It is about 3 kilometers on the ground and underground. It takes only 2 hours to walk slowly. The underground scenery is still good. There are not many people on Saturday. The price is a bit more expensive.

Going in summer, it is cool and fun, there are too many drifters, no queues, because it is also very fun to walk! Going to escape the summer heat in summer is definitely a good choice, children and adults have fun...recommended

Overall, the tickets are not cheap, there are still too many people going during the holiday, especially when I first entered the hole, I feel that if there is a problem, I can't escape it. The rafting looks very fun, but unfortunately it takes a long time to queue. There is no experience.

The scenery is good, the environment is clean, the hole is particularly cool, the rafting is fun, but unfortunately it is only a short section, it will be longer.

The scenery is good, the cave is very cool, the rafting is also very interesting, the environment is clean, it is worth a visit.
