They require a 40-inch height for Cave of the Winds.

Yes, there is a minimum height requirement: 40 inches (about 102 cm). There is no specific minimum age — if your kid is tall enough, they’re welcome. Below that, they can’t go on the wooden walkways near the falls. It’s a safety thing, not a gatekeeping thing.

They do provide ponchos and sandals for everyone, including smaller sizes for children. The sandals are the cheap foam kind, but they work fine. You can also bring your own water shoes if you prefer. Ponchos are disposable but effective — you’ll still get wet, just less soaked.

If your child is close to 40 inches, measure before you go. There’s no leniency on that line.
