3. Unaweep Tabeguache Scenic Byway

Location: State Highway 141 and 145 in Colorado
Known For: Rugged terrain, sharp turns
Complex Says: Native American buildings, waterfalls, sweeping changes in terrain, and a near-constant view of Utah's massive La Sal mountains offer loads to love as you and your sweetheart meander along. Or take it at speed, which many people like to do. Romance is in what you and your partner like to do together, and if speed gives you thrills, we certainly won't argue.
