The popular hike runs cliffside high above the Brule River. After a spur to the Lower Falls, make the final climb to where the river splits. The eastern flow tumbles over the High Falls while the western arm drops into the Devil’s Kettle, final destination unknown. While the roar of the river is spectacular in the spring, it can be hard to see the Devil’s Kettle. If that is your goal, head out midsummer or later when the spring flow has subsided.
