Colorado isn’t just one of the best places to go whitewater rafting in the United States. By most measures (the variety of rivers, the range of difficulty, the sheer mileage of raftable water) it’s one of the best places in the world for whitewater rafting.
The state has more than a dozen commercially rafted rivers, running through landscapes that shift from high alpine meadows to deep desert canyons within a few hours’ drive. Whether you’re a beginner looking for your first float or an experienced paddler chasing Class V water, Colorado has rivers for all skill levels.
If you’re looking for the best whitewater rafting in the state, you’re already on the right river. As a Colorado rafting company, we’ve been here for more than 50 years of experience guiding the Arkansas, and here are the five raft tours worth your time in 2026.
#1 – The Royal Gorge | Cañon City, Colorado
Class IV (V) | Ages 14+
There’s a reason the Royal Gorge consistently lands at the top of every serious Colorado rafting list. More than just floating through beautiful canyon scenery, this is a trip you take to test yourself against some of the world-class whitewater in North America. This trip is built for thrill-seekers ready to test themselves.
The Royal Gorge section of the Arkansas River (just eight miles west of Cañon City and an hour from Colorado Springs) carves through 1,000-foot granite walls. Your raft navigates through a canyon so deep and narrow that the famous Royal Gorge Bridge (once the highest suspension bridge in the world) looks like a thread stretched across the sky above you. The rapids here are relentless and technical: Sunshine Falls drops you into a churning hole, Sledgehammer lives up to its name, and Wall Slammer makes it personal. These aren’t names chosen for marketing purposes: they’re real descriptions.
The full-day trip runs 5-6 hours and includes a warmup through Bighorn Sheep Canyon in the morning before the Royal Gorge itself in the afternoon, plus a riverside lunch between the two. The half-day option cuts straight to the gorge: Sunshine Falls, Sledge Hammer, and Boat Eater in 2-3 hours, no filler.
Strong swimming ability is required, and we mean it. Safety is our top priority, and guests need to be physically fit and comfortable in turbulent conditions. But if that’s you, the Royal Gorge is hard to top.
#2 – Browns Canyon National Monument |
Buena Vista, Colorado
Class III (IV) | Ages 6+
The iconic Browns Canyon National Monument (six miles south of Buena Vista) is the most popular section on Colorado’s Arkansas River, and it earns that reputation time after time. If the Royal Gorge is about intensity, the iconic Browns Canyon is about everything else: genuine whitewater, spectacular scenery, wildlife around every bend, and an experience that’s perfect for your first time on the river.
Your raft will work through Class III (IV) rapids with names that tell you what’s coming next: Zoom Flume accelerates you through a narrow chute, Pinball bounces you between boulders, and Sidell’s Suckhole is exactly what it sounds like. In between the action, the river opens up into long stretches of moving water with views of the Collegiate Peaks and the Sawatch Range filling the horizon.
The half-day trip covers 10 miles and seven rapids in 2-3 hours, enough to get a real taste of the canyon without a full-day commitment. The full-day option runs 13+ rapids over 5-6 hours, includes a catered riverside lunch, and gives you the Browns Canyon experience.
What sets the Buena Vista outpost apart is what happens after the rafting. River Runners‘ put-in is right at the canyon entrance, so there are no long bus rides in your day. And when you get off the water, The Beach Restaurant and Bar is right there on-site: food, cold drinks, and a riverside patio to decompress and relive the run – perfect for large groups to gather after the trip.

#3 – The Numbers | Buena Vista, Colorado
Class IV (V)
The Numbers runs just upstream from Buena Vista, putting in from the same Browns Canyon Outpost as trip #2 (but the experience is way different). This stretch of the Arkansas River, just upstream from Buena Vista, earned its name for a good reason: rapids No. 1 through 7, one after another, with barely enough flat water between them to catch your breath. So don’t expect a warmup: you drop in and it starts immediately.
The Numbers sits in a completely different landscape from the other two raft trips on this list. Where the Royal Gorge is a deep canyon and Browns Canyon is a granite monument, The Numbers is alpine: open sky, fast water, and purely about paddling.
The full-day trip continues through the Narrows and the Miracle Mile, more continuous whitewater on top of an already demanding run.
This one demands fitness and real swimming confidence. The rapids are continuous and technical, and the teamwork requirement is higher than anything else on the Arkansas. Thrill-seekers and experienced paddlers come back to The Numbers year after year.

#4 – Clear Creek Idaho Springs, Colorado (30 minutes from Denver)
Class III-IV
If the Arkansas River is Colorado’s rafting heartland, Clear Creek is its most accessible front door. The river is a short drive from Denver: just 30 miles west via I-70, being the closest serious whitewater to the city. Clear Creek is the steepest raftable river in Colorado, generating more rapids per mile than any other run in the state. The narrow canyon walls keep the water fast and technical in a way that surprises people who expect something tame just because it’s close to the highway.
Available raft trips cover everything from Class II-III runs (perfect for first-timers and families with young kids) to Class IV canyon sections that demand real paddling ability. The historic gold rush town of Idaho Springs sits right at the put-in, which gives the whole experience a grounding in Colorado history that most river trips don’t have.
For anyone based in Denver looking for a same-day whitewater fix (or a warm-up before a bigger Arkansas River trip) Clear Creek is the honest answer.
#5 – Gore Canyon Colorado River, near Kremmling
Class IV-V | Experienced rafters only
Gore Canyon is one of the reasons Colorado has a reputation for whitewater rafting. This section of the Colorado River near Kremmling is widely considered the most demanding commercially rafted run in the state: a steep, technical gorge of Class IV and V rapids that requires fit, experienced paddlers and expert guides. During the high water season, it’s genuinely relentless.
Gore Canyon delivers world-class whitewater in a remote setting: sheer walls, fast water, and spectacular scenery you only reach by river. It’s a different side of Colorado than most visitors ever see.
Season matters here more than anywhere else on this list. Gore Canyon runs roughly from Memorial Day through Labor Day, and peak flows in late May and June produce the most intense conditions. If you’re ready for it, there isn’t a more challenging day on the water in Colorado.
Planning Your Trip: What to Know
Prime season on the Arkansas runs from mid-May through early September. High water season (and the most intense conditions) hit around mid-June. The best time to raft is late June through July: still exciting, but more manageable for most groups. August and early September see water levels drop, which actually opens up some trips to younger and less experienced groups, including young children.
All three raft trips go out rain or shine (rafting is a wet sport anyway). Bring moisture-wicking layers (wear a bathing suit under quick-dry shorts or athletic pants), secure footwear (no flip-flops), sunscreen, and a dry set of clothes for after. River Runners has guided guests on the Arkansas River since 1972, and provides wetsuits, splash jackets, helmets, and neoprene river boots on every trip. All trips include comprehensive safety briefings and certified guides. We also handle large groups: corporate outings, scout troops, bachelor and bachelorette parties, and celebrations of all sizes.
Cancellations made at least 48 hours in advance receive a full refund. Less than 48 hours gets you a rain check minus $10 per person.
