Upper Colorado River Inflatable Kayak Trip

Beginner level

Ages 13+ welcome

Half-day tour

Add a splash of adventures to your Upper Colorado River trip! Inflatable kayaking down the headwaters of the Colorado River near Rocky Mountain National Park is an exciting way to experience this whitewater gem. Participants will navigate the river in either solo or tandem inflatable kayak while a certified raft guide leads the way. Inflatable Kayaks will accompany our rafting trips down the river, so part of your group can opt to float the river in rafts by booking a rafting trip scheduled for the same time, while other members of the group can paddle along in I.K.s. Previous paddling experience is recommended.


Enjoy top-of-the-line equipment, including a wetsuit and splash jacket — all included in the tour price

Step away from the beaten path and check out what Colorado has to offer. This trip begins at Pumphouse campgrounds and flows downstream 5.5 miles through several class I-II rapids and an exciting class III rapid. This run casts a unique backdrop and is a favorite among commercial and private boaters alike. The “Upper-C” is a true gem of the Colorado Rockies.



The Mighty Upper Colorado starts high in the Rocky Mountains, west of Rocky Mountain National Park, and meanders through breathtaking landscapes of valleys and canyons. If you’re a beginner or seeking a relaxing and scenic float trip, this stretch of water is perfect for you.

Good to Know

Why Upper Colorado River Inflatable Kayaking?
The Upper Colorado River is a wild and scenic river and breathtaking vistas are in abundance on this stretch of water. This is considered one of the most popular family floats in Colorado.

Our location
Downstream Adventures’ Kremmling Outpost is nestled in the heart of the Colorado Rockies less than an hour from Winter Park, Grandby, Estes Park, Vail, Breckenridge, Keystone, and Steamboat Springs. The views along the drive are nearly as stunning as what you will experience on the river!

What you’ll see
The Upper Colorado River is a place of stunning beauty. Rich with natural beauty and an abundance of wildlife, the Upper C is a nature lover’s paradise. Keep an eye peeled for deer, big-horn sheep, pronghorn, elk, moose, bear, otters, bald eagles, and many other migratory birds.

Qualifications of our guides
At Downstream Adventures, we guarantee that all of our guides are highly qualified and experienced. Each guide has been certified in CPR/first aid and trained in life-saving swiftwater rescue techniques, and that’s just our minimum requirement!

Our guides are some of the most experienced in Colorado and are skilled in Swift-Water Rescue and precision boat control. Of course, you are entering a wild and natural environment and there are risks involved, but we at Downstream Adventures take great pride in making trip safety our top priority.
