The falls are a jewel of Oklahoma tourism. Once you’re at the bottom, all of the effort is worth it. The moderate rating comes from a short section of elevation gain along a natural path that does get fairly steep. You can see the falls from a viewpoint at the very top, but if you’re able, follow the boardwalk path to the lower level for views from below.
While there is indeed a spring and a little lake along the way, the big payoff here is the park’s 77-foot-tall waterfall. This loop trail is why most tourists travel to Natural Falls State Park.
