Dinosaur Diamond

Dinosaur Diamond Scenic Byway map

Length: 134 miles (486 miles total CO/UT) 
Driving time: two to three days

Some of the world's most significant dinosaur fossil quarries and museums are clustered along this route, in the midst of a forbidding but stunningly beautiful landscape. The earth, fractured and stained, coughs up a rare collection of treasures. Ancient stone rises to the surface after eons underground; skeletons buried 100 million years ago now bleach in the desert sun. The byway traverses high mountains and barren plateaus, with stops at two national parks, two national monuments, and two great rivers of the West(the Colorado and Green). This dramatic maze of rocks and bones defies the imagination.

Dinosaur Diamond was designated by the U.S. Secretary of Transportation as a National Scenic Byway in 2002. It is one of 13 America's Byways® designated in Colorado.
