Moab to Alpine: Ultimate Road Trip Guide

The Moab-to-Alpine corridor traces the western edge of the Colorado Plateau, crossing the Green River at the historic Dewey Bridge (originally built 1916, now a pedestrian span). This 370-mile route on US-191 and US-189 delivers a vertical climb of nearly 6,000 feet, from Moab's 4,000-foot desert to Alpine's 5,600-foot mountain valley. It is worth driving Moab, UT to Alpine, WY for the sheer geological palette shift alone: red Navajo Sandstone yields to gray limestone and finally to granite peaks.
