The Kings River in northwest Arkansas - like the Buffalo, is one of those few remaining pristine, free-flowing streams in the country. A float trip on this river is truly an unforgettable experience, as you meander through the rock of the high Ozark Plateau. The various waterfalls in the Leatherwood Wilderness south of Mountain Home will also astound you with their beauty as you hike above, below and behind them. Episode concludes with a special look at "Valley of Vapors" - the hot springs that were set aside as a federal reservation and eventually became - Hot Springs National Park.
