Your better off to lock evetything in your car for safety measure
There are locker only big enough for a phone and wallet, but they give you a box for bigger items that they keep in their office.
We didn't kayak, which is in a different spot. Typically speaking, regarding springs in general, you usually leave belongings in car. In other words, I have no idea. You could always call them. It's beautiful there!! Be sure to ask if you can see the waterfalls when kayaking. I didn't see any way possible to view them while in kayak. May be wrong on that too. Enjoy!!
