It's hard to compare the upper and lower falls in the park to each other. While it is a little bit small, McKinney Lower Falls is no less impressive than its larger counterpart. You have the opportunity to get wet here if you want.

You should be careful when walking barefoot through the water, or you'll just get wet :-)
