You can't even see the whole waterfall! We had to pay in cash too, so we had to go back to town to get cash then come back and for a disappointing partial waterfall.

Was expecting something completely different with the way they market this attraction. Needless to say, it was pretty cool to see a waterfall inside a mountain, it was not worth the $8 USD each!
You don't even get to see the whole falls, you maybe get to see a 8 foot opening of where the water is falling.
Don't recommend this as one of your first choices!!!

As many other folks have said, save your $7.50 a person. You walk thru a dug out cave to see the lower 20 feet of a waterfall. Doesn't even make a good picture. The waterfall outside is worth the visit and there's no cost to look at it. The drive back thru the canyon is nice. Fortunately we had VIP passes that got us free admission. I'd have really been upset if we had to pay and I feel sorry for those who do. With the money they make from unsuspecting visitors they could at least repaint the signs inside the cave.

Paying was not the problem ... we glading donate for the viewing, but at $7.50/adult and $3.50/child ... it's not worth the 5 minute walk. You walk along a mine shaft which goes through the middle of the mountain. At the end, there is a waterfall ... sort of. You expect to see a 600 foot waterfall, but in reallity, all you see is the bottom 20 feet of the fall which is flowing between the mountains. You cannot see up to where it is coming from. Nice story, but even the kids advsied that this was a waste of time and money.
