Colorado River Rafting
Raft the Colorado River
From the peaks of the Rockies to the depths of Grand Canyon and beyond, the Colorado River is the West’s most iconic river. At more than 1,400 miles in length—passing through seven U.S. States and 11 national parks and monuments—it’s not only the lifeline of the Colorado Plateau, the Colorado River is one of the best whitewater rafting destinations in the world.
Inhabited for centuries by the Navajo, Mojave, Ute, and many other tribes, as well as their native predecessors, the Colorado River Basin provided rich grounds for hunting, fishing, and gathering. The lush riparian areas helped native communities flourish, and the wide flows allowed them to travel up and downstream.
It wasn’t until John Wesley Powell’s harrowing 1869 exploration of a large section of the river that the hidden canyons and raging rapids of the Colorado were put on the map. After that, it didn’t take long for other explorers and early river-running pioneers to follow in Powell’s footsteps.
Today, despite dams and development restraining the free flow of the river in many places, much of the Colorado’s wild and rugged beauty remains and is now protected. Though flows are carefully regulated, Colorado River rafting adventures consistently provide world-class whitewater and the trip of a lifetime.

The guides made this trip so special, worthwhile, and memorable. Having booked the 17-day Grand Canyon trip on only two week's notice, I truly wasn't sure what to expect and decided to come into the adventure with an open mind and "just say yes" attitude. I was shocked to experience the level of hospitality provided 24/7 by the guides. Even more impressive was the guides' passion and expert knowledge of the Grand Canyon's geology, anthropology, and rafting history.OARS Grand Canyon guest 2022

Frequently Asked Questions
Have more questions?
Where is the best Colorado River rafting?
As the Colorado River flows through southeastern Utah and Arizona, it snakes its way through some of the West’s most dramatic canyon country, including Canyonlands National Park and Grand Canyon National Park.
Some of the best Colorado River rafting opportunities are easily accessible from the adventure hubs of Moab, UT, and Flagstaff, AZ, including three of the most stunning and exciting sections of whitewater: Westwater Canyon, Cataract Canyon, and Grand Canyon. On all three of these white water rafting trips, fascinating geology, incredible camping opportunities and incredible hiking opportunities await.
How long are rafting trips on the Colorado River?
Depending on how much time you have, OARS offers a variety of rafting trips on the Colorado River ranging anywhere from 2 to 18 days.
For Westwater Canyon, 2- to 3-day options are the norm, with 3 days providing a more laid-back experience and more exploring. Slightly longer trips ranging from 4 to 6 days are available through Cataract Canyon, where you can enjoy incredible backstage access to Canyonlands National Park.
The longest Colorado River rafting trips available are full Grand Canyon rafting and dory expeditions, which float the entire 280-mile stretch of the Colorado River from Lees Ferry to Pearce Ferry and typically last 14 to 18 days. Partial canyon trips normally range between 6 to 12 days.
Does OARS offer day trips?
OARS doesn’t currently offer 1-day rafting trips on the Colorado River. If you’re short on time, the Moab Daily run or the shorter, 12-mile Westwater Canyon trip, are popular day trips for adventure seekers.
What are the rapids on the Colorado River rated?
Most of the rapids on the Colorado River are rated on the standard scale of I-VI. Everyone from beginners and families to thrill seekers and seasoned river runners can find a Colorado River white water adventure that caters to their experience level.
River ratings and adventure levels on the Colorado vary by section, and even the water level or season. For example, Cataract Canyon trips are generally considered Class III-IV, however at peak flows in the spring, some of the more technical rapids like the Big Drops are as big or bigger than the most formidable rapids in Grand Canyon.
Grand Canyon rapids are rated on a different scale of 1 to 10. Flat water is 1, while tough rapids like Lava Falls or Crystal can be rated 10 at certain water levels. A 10 rating in the canyon is roughly equivalent to a Class V in the standard river scale.
What is the minimum age to raft the Colorado?
OARS offers multi-day river trips on the Colorado that cater to ages 7 and up, depending on the trip and water levels. Refer to trip pages for minimum age requirements for each adventure.
River ratings, other inherent risks of backcountry travel, and even an individual’s adventure threshold and activity level should be considered when deciding if a person is ready for a river trip.
When is the best time to go rafting on the Colorado River?
Guided rafting trips on the Colorado River are generally offered April through October, but conditions can vary greatly depending on when and where you decide to go. The best time to raft the Colorado River really depends on individual preferences, like desired adventure level, boat preference, and other factors, like threshold for extreme weather both hot and cold.
Trips early in the commercial rafting season offer fun, average flows for rafters, typically during April and early May before the spring melt begins in full force. Wildflowers are blooming, waterfalls are gushing, conditions are ideal for hiking, and there are fewer people on the water. However, paddlers need to be prepared for frigid water and unpredictable weather that can go from warm and sunny to raining, or even snowing, on the same day.
Later in spring, often mid-May through mid-June, snowmelt runoff from the Rocky Mountains adds abundant amounts of water to the river. “High-water trips” on the more free-flowing and untamed stretches of the Colorado River, like Cataract Canyon, during these peak flows are best for thrill seekers and the most adventurous rafters. A raft flip or cold water swim should be anticipated. At the same time, rapids in narrower sections of the Colorado River, like Westwater Canyon, tend to wash out completely during high water. As a result, OARS doesn’t offer Westwater trips during the peak-flow window, since it can be a disappointing experience for paddlers.
As Colorado River flows return to normal by late June to early-July most seasons, both Cataract Canyon and Westwater Canyon offer splashy, reliable flows for rafters into the late summer/early fall.
Westwater Canyon rafting trips typically conclude by the end of September, since the water levels can become more challenging for rafts to navigate later in the season, while Cataract Canyon trips are often available into mid-October, depending on the outfitter.
During this time, we’re generally able to offer a wider selection of crafts to try out on calmer stretches of the river, like stand-up paddleboards or inflatable kayaks, and the heat of summer is a welcome invitation to swim in the brisk Colorado. Rafters aren’t immune to unpredictable weather in the summer, though. During monsoon season (July through September), rafters can anticipate frequent afternoon thunderstorms.
Grand Canyon River Trip Considerations
The best time to raft Grand Canyon is a bit of a different scenario. Before the Colorado River flows through Grand Canyon, it hits Lake Powell. As a result, Grand Canyon rafting trips rely on dam-controlled water releases from the upstream reservoir all year long. This means rafters won’t necessarily see drastic changes in water levels during spring snowmelt season, but the big legendary whitewater that Grand Canyon is known for is guaranteed throughout the Colorado River rafting season. Arguably, the months of April and October are considered the best time for Grand Canyon rafting trips, because there are fewer people in the canyon, temperatures are milder, and the conditions are ideal for side hikes and exploring.
