Moab to Green River Road Trip: Epic Utah-Wyoming Drive

The drive from Moab, Utah to Green River, Wyoming spans approximately 375 miles along US-191 and I-80, taking about 6.5 hours without stops. This route crosses the historic Lincoln Highway, the first transcontinental highway in the US, and passes through the eastern edge of the Uinta Basin.

Along the way, you'll traverse dramatic red rock canyons, high desert plateaus, and the vast Wyoming sagebrush plains. The journey offers a stark contrast between Utah's iconic sandstone formations and Wyoming's open rangeland.

The route passes through three distinct eco-regions: the Colorado Plateau's red rock country, the Uinta Basin's badlands, and the Wyoming Basin's shortgrass prairie. Key geological features include the Book Cliffs, which stretch for 200 miles along the Utah-Colorado border.
