Twin Falls is one of the more famous waterfall areas in Northwest Arkansas. I first read about this falls about 10 years ago in Backpacker Magazine and was quick to add it to my list. It really is worth the national exposure.
The falls is actually two different falls of two different creeks -- the Big Devils Fork and the Long Devils Fork -- that merge together at this waterfall site. One of the falls is 17 feet tall, the other 19 feet tall, and they fall over into a glistening pool that is a great swimming hole.
The easiest trail head to get to is via the Richland Creek campground -- and is a spectacular hike. When coming to the area, be sure to also check out Richland Falls and many of the other beautiful areas within the Richland Creek Wilderness Area.
This really is one of the most worthy destinations in the Ozarks. Difficult to get to, but worth the effort.
