The parking spot of this is on the opposite side of the road, you'll notice a small asphalt patch that then also leads into a spot where there's room for a couple more vehicles. These falls are listed in Tim Ernst's "Arkansas Waterfall" guide, and the volunteer trail that leads from the Highway and on down to the falls is now well trodden. The trail down can be just a little steep in places, but there are no major obstacles to have to work around. You'll pass by a small waterfall on the creek that feeds Dewey Canyon Falls right as you are nearing them. Bumpers Falls (upper) is visible from Dewey Canyon, and you can walk behind them and then along the "ledge" if you'd like to track on to see Heuston Falls. There is a well placed ladder shortly before Heuston Falls that is the best way to get down to the bottoms of all three falls.
