Dinosaur National Monument is located in both Colorado and Utah. Each state also provides a chance to visit very distinctive areas of the monument. The east side of the monument located in Colorado provides access to deep canyons along the Green and Yampa rivers. Dramatic views are available along the Harpers Corner Road. The west side of the monument located in Utah features the world-famous dinosaur quarry where visitors can see over 1,500 fossils still embedded in the cliff face.

The Dinosaur Quarry Exhibit Hall and Quarry Visitor Center, one-half mile from the Quarry, are open year round. They are found by taking Highway 149 north from Jensen, UT to the park. Rangers lead visitors up to the Quarry by car caravans between October and April.

The Canyon Area Visitor Center, located on U.S. Highway 40, two miles east of Dinosaur, CO, is closed for the season. The Colorado Welcome Center is located 2 miles from the Canyon Visitor Center and they are open daily through November, but closed during the winter. The Welcome Center is located in the town of Dinosaur, CO. There are no fossil displays in the canyon area of the park.
