Upper Colorado River Scenic Byway (UT-128)

44.6-mile two-lane highway north of Moab that follows the Colorado River through a corridor of sheer sandstone canyon walls. The route runs from US-191 just north of Moab north to I-70 near Cisco. Key highlights include Fisher Towers, Castle Valley, and views of the snow-capped La Sal Mountains mirrored on the river. Road narrows in the canyon section; most curves require reduced speed. Officially designated the Upper Colorado River Scenic Byway and part of the Dinosaur Diamond National Scenic Byway.
