The paved highway over the crest of the Bighorn Mountains winds past a dense forest, lavish pastures, stunning waterfalls, and gorgeous deep canyons. Stretching from the Powder River Basin to the Bighorn Basin, the Bighorn Byway follows US 14 from the west outside Greybull, according to Travel Wyoming.
