Journey through 480 miles of ancient wonders on this spectacular loop connecting Colorado and Utah, where millions of years of Earth’s history unfold before your eyes. The Dinosaur Diamond Prehistoric Highway earned its National Scenic Byway designation for good reason—this is one of the richest paleontological regions on the planet.

Trace the route from Price through Moab and on to Vernal, passing through landscapes that seem frozen in time. Towering red rock formations, deep river canyons, and vast desert plateaus create a dramatic backdrop for world-class dinosaur quarries and fossil sites. Stop at the Utah Field House of Natural History, explore Dinosaur National Monument’s famous quarry wall embedded with over 1,500 dinosaur bones, and visit the Museum of Western Colorado’s Dinosaur Journey.

Beyond the prehistoric treasures, you’ll encounter the breathtaking scenery of Arches and Canyonlands National Parks near Moab, the rugged Book Cliffs, and the Colorado River’s sculptured canyons. The route through Rangely to Loma reveals Colorado’s remote high desert beauty.

Spring and fall offer ideal driving conditions with mild temperatures and golden light. Allow three to four days to fully appreciate the museums, hiking trails, and scenic overlooks along this prehistoric paradise. This is a drive through deep time itself.
