Beautiful park. Hidden in the stunning Ozark Highlands near the Arkansas/Oklahoma border. Visitors are not allowed to swim under the waterfall, but there is a side area where they can play around in the water. The waterfalls are not massive, but you can do some hiking around them. Not an all-day adventure, but definitely something you can spend a couple of hours doing. Also, you have the option to stay overnight in one of the park's five yurts, which can be booked online. It's a great place to visit if you're in NWA or Tulsa.
