The section of the Yampa River that flows through Colorado's Dinosaur National Monument is one of the most beloved river trips in the country. The canyon is full of incredible desert scenery, archaeological masterpieces, and spacious campsites and offers some of the best hiking opportunities on a western river. Because it is the only free-flowing river in the entire Colorado River Basin, flows fluctuate naturally and trips have an exceptional sense of wildness to them.

The Yampa can be done in five or six days which includes about three days on the Yampa and two or three days below the confluence with the Green River, all of them within Dinosaur National Monument. The second section on the Green goes through historic Echo Park which was the site of proposed dams and the birthplace of the modern environmental movement. In a strategy that David Brower called the most regrettable decision in the history of the Sierra Club, Echo Park on the Green was protected and Glen Canyon on the Colorado was sacrificed, dammed and flooded.

ARTA River TripsARTA River Trips (800) 323-2782 is a non-profit organization that runs 14 of the best rivers in the West.

Most rapids are Class II or III with the exception of Warm Springs which is a big class IV rapid with a flipper wave to avoid and some additional holes. The campsites are spacious and several offer side hikes to view points or archaeological sites. The canyon walls are incredible and offer jaw-dropping views and vistas for the majority of the trip. The museum and quarry near the take-out are fascinating and worth a visit.
