From Colorado to Utah, here are the most popular whitewater rafting sections of the Yampa River:
Steamboat To Craig
The first popular whitewater section of the Yampa river is made up of 65 miles of Class II and III rapids. The route begins in Steamboat Springs, with river access typically putting boaters in at Shield Drive or Little Toots Park.
After 25 miles of mostly public property, the first take-out opportunity is at the Hayden Pump Station. From here, most rafters continue their journey to Craig, ending at the Yampa Valley Golf Course, Loudy Simpson Park, or South Beach access points.
Rafting this route in its entirety is highly dependent on water levels, due to low bridges and diversion dams. Overall, the ride is very smooth, with the most challenging section being the Steamboat Whitewater Park at the beginning of the journey.
Little Yampa Canyon / Juniper Canyon
The next 50 miles of the Yampa river provide remote and playful whitewater rapids. This section starts by cutting through the Little Yampa Canyon 32 miles towards the Duffy Mountain access point.
This is a popular stop for multi-day rafting trips, with the diversion dam and Class III+ rapids of Juniper Canyon awaiting downstream in the morning. From there, large bouts of continuous Class II rapids flow to the Maybell Bridge access at the end of the section.
Maybell to Cross Mountain
For the most part, the only people who are lucky enough to raft from Maybell to Cross Mountain on the Yampa River are in the midst of a five or six day whitewater trip. This remote section covers 29 miles of Class II whitewater with ample opportunity for wildlife viewing and star gazing.
Cross Mountain Gorge
Cross Mountain Gorge is the most challenging and infamous section of the Yampa River. After a nice long float, the boulder field and sharp canyon walls of Cross Mountain Gorge could terrify an unsuspecting rider.
This is the thirteen mile section of the river that separates the pros from the wannabes, with some of the most technical Class IV – V rapids in Colorado. After, Cross Mountain Gorge rafters can take-out at the Deerlodge Park access or continue westward overnight.
Yampa Canyon / Dinosaur National Monument
Colorado’s last popular section of the Yampa River stretches through the towering sandstone walls of Dinosaur National Monument. The 46 miles stretch is mainly smooth sailing among occasional Class II and III rapids. Typically, rafters will take between 3 and 5 days to raft and camp in this breathtaking isolated wilderness area.
