How much does the boat fee for drifting in the underground grand canyon cost? I'm saying it's not with a tour group, self-driving travel, is it 60 yuan per person? Hurry hurry hurry!

Drifting alone for 60 years, with only one pair of shoes left.
Found the ticket, it’s 60, half price for children is 30, each ticket comes with a pair of shoe covers.
If I don’t go, then I won’t regret going; the scenic area is all garbage, people are crowded together, everyone who goes regrets it!
Two large ones and one small, 150, small is 130cm, don’t know whether it’s the full price or half price.
One person 60 yuan, free ticket below 120.
