The Harpers Corner Trail provides sweeping views of the canyons of the Green and Yampa rivers and geologic features such as the Mitten Park Fault.



Located on the Colorado side of the monument, Harpers Corner Drive is a scenic, 32-mile (55-km) road that leads to the heart of Dinosaur National Monument's canyon country. Overlooks offer sweeping vistas of the Green and Yampa river canyons. Several picnic areas and the trailheads of three hiking trails are located just off Harpers Corner Drive. On one trail, sharp-eyed hikers can spot fossils of small sea creatures that lived long ago. Visitors prepared for remote driving conditions can access two unimproved roads from Harpers Corner Drive.

Fuel, food, and other services are not available along Harpers Corner Drive. The nearest services are in Dinosaur, Colorado, two miles west of the Canyon Area Visitor Center on Highway 40.

Winter Recreation
During the winter, cross-country skiing and snowmobile use are allowed on the closed portion of Harpers Corner Drive, beyond Plug Hat Butte. Throughout the winter, the first five miles of Harpers Corner Drive remain open and plowed to allow public access to the Plug Hat parking area for snowmobile and cross-country ski enthusiasts. Snowmobiles are not allowed off the road surface and may not go past the Echo Park Road turn-off.

At the end of the Harpers Corner Trail, look closely at the rock underfoot. Those with a keen eye and a bit of patience will find the fossilized remains of small sea creatures that lived hundreds of millions of years ago. Look for the clam-like shells of brachiopods and for pieces of the stems of crinoids, ancient relative of the starfish. The rock around these fossils was once mud at the bottom of an ancient sea. There are no dinosaur fossils in the Harpers Corner area.
