It is 19.95 dollars for an adult, so around 40 or so.
Buy the package, it is discounted. Well worth the price.
If you buy a package (ruby falls, rock city garden, incline railway) it's about $49.90 per head. Worth the package! Browse to find out more about the other two. You can finish a sufficiently good part of them all in as long as a day at work, although you could spend a whole day at just the Rock City Garden. It's beautiful!
It's 20$ per adult for the falls itself. If you want to do other attractions, it's extra.
