Easily one of the most beautiful sights in Arkansas, the view from Big Bluff looking down on Buffalo National River will amaze you. Established in 1972, Buffalo National River flows freely for 135 miles and is one of the few remaining undammed rivers in the lower 48 states. Once you arrive, prepare to journey from running rapids to quiet pools while surrounded by massive bluffs as you cruise through the Ozark Mountains down to the White River. Photo by Aaron Bates.
