The Kings river Falls are located near Witter in North West arkansas. There wasn't that much water flowing over the falls when I visited. The trip involves some driving along dirt roads – watch out for locals on tractors – and about a mile or so hike along a well worn footpath along the western river bank. It's a pretty level hike but as I recall, one or two of the boulders on the path represented considerable steps. This is a view from the top of the falls looking down into the pool at the base. I've seen plenty of photos taken in times of greater flow where you just wouldn't be able to stand where I was standing for this shot.
