Starting from the town of Dinosaur in northwestern Colorado, travel approximately 1 mile east on Highway 40.  Turn left onto the Harpers Corner Road and travel for approximately 24 miles.  Turn right into the Echo Park Road and travel approximately 13 miles to the Echo Park Campground. When you reach the campground, travel an additional 800 feet to the Group Campsite. It takes most visitors around 90 minutes to travel from the town of Dinosaur to the Echo Park Campground Group Site.  The road can become impassible in wet conditions.  Be sure to check with the National Park Service concerning road conditions if the weather is a factor.

Our partners at Unitah County are having a week long celebration to commemorate the 150th anniversary. Information about the entire event can be found at:
