Two major rivers converge in the canyon country of Dinosaur National Monument—the Yampa and Green Rivers—which make rafting trips on both rivers the ideal way to explore this unique geologic area.
The Yampa River is the only major tributary in the Colorado River system that still runs wild and free, straight into the heart of Dinosaur National Monument. A Yampa River rafting trip offers paddlers exciting Class III or IV whitewater rafting (depending on water levels) through colorful canyons where a billion years are captured within walls that tower more than 1,000 feet above the river in some places. Along the way you’ll marvel at mysterious rock formations like Cleopatra’s Couch, hike to places such as Whispering Cave and Stubb’s Cabin, and explore parts of Dinosaur National Monument few visitors ever see.
On a Green River rafting trip through the Gates of Lodore you’ll wind your way through three distinct canyons—Lodore, Whirlpool, and Split Mountain—all of which contain geological curiosities and rich human history. As the river twists through a catacomb of scarlet slot canyons, yawning valleys, and lush ledges of emerald evergreen and brush, you’ll be able to explore a fascinating land where dinosaurs once roamed. The Green River offers numerous side hikes, relaxing nights on the beach, and moderate whitewater perfect for young families and laid-back vacationers.
