Staying Cool on the San Juan River with Colorado River Rafting & More

Summer in Pagosa Springs means one thing: river time. With the snowmelt flowing down from the high country, the San Juan River becomes the heart of all things cool, splashy, and wildly fun. Whether you're here for an adrenaline-pumping ride through whitewater rapids or a lazy float under the sun, the river offers something for every type of adventurer. And with our award-winning Pagosa Springs Hotel just steps from the river, you’ll have the perfect basecamp to dry off, relax, and do it all again tomorrow. 

The Story of the San Juan River 

Before you dip a paddle in the water, it’s worth knowing a little about the river beneath you. The San Juan River, named by early Spanish explorers after Saint John the Baptist begins in the snow-covered peaks of the San Juan Mountains in southwestern Colorado. From there, it flows for over 380 miles through Colorado, New Mexico, and Utah before feeding into Lake Powell. 

This river has long been a lifeline in the Four Corners region. Its waters have sustained Indigenous communities, supported ancient agriculture, and inspired Navajo mythology, where it’s sometimes known as Old Age River or One-With-a-Wide-Body. Today, its upper stretches near Pagosa Springs offer a pristine playground for whitewater enthusiasts, kayakers, and anyone looking to cool off in the heat of summer. 

The River’s Rhythm: Flow, Seasons, and Safety 

What makes the San Juan River such a dynamic place for adventure? It’s all about the flow. 

River flow is measured in cubic feet per second (CFS). Once the snowmelt kicks in, levels rise and change daily, creating the perfect conditions for different kinds of river fun. 

• Over 600 CFS: Whitewater rafting and kayaking are at their peak. 

• 250–400 CFS: High and splashy tubing conditions for thrill-seekers. 

• 90–150 CFS: Ideal for families looking for a gentle float.

Whitewater Rafting the San Juan 

If you’re chasing adrenaline, you’ll find it on the 13-mile stretch from Yamaguchi Park to Mesa Canyon. This section includes Class II and III rapids, remote canyon views, and a mandatory run through Llama Falls, a sheer volcanic drop that’s both beautiful and exhilarating. Peak rafting season hits in April and May, when melting mountain snow feeds the river and kicks the rapids into high gear. It’s a bucket-list experience for intermediate rafters or first-timers going with a guide. 

You’ve got some excellent local options for planning your rafting adventure, and each outfitter brings something a little different to the table: 

Pagosa Outside 

A trusted name in river recreation, Pagosa Outside offers a range of rafting experiences, from beginner-friendly trips to more adrenaline-pumping runs through Mesa Canyon. Their all-inclusive packages cover everything: high-quality gear, life jackets, river shoes, and even complimentary digital photos.  

Pagosa Rafting Outfitters, Inc. 

With experienced, safety-conscious guides and a wide variety of rafting tours, Pagosa Rafting Outfitters, Inc. is another great option for both scenic and whitewater routes. They also rent kayaks, tubes, and stand-up paddleboards (SUPs) if you want to switch things up. Whether you’re looking for a mellow float or a fast-paced thrill ride, their team ensures a safe and memorable trip. 

Pagosa Adventure 

Pagosa Adventure specializes in customizable experiences like the Pagosa Springs Town Run, a family-friendly rafting tour led by knowledgeable guides who make safety a top priority. For something truly unique, consider their Fly and Float combo, where you’ll start your day with a breathtaking hot air balloon ride before hitting the river. It’s a bucket-list-worthy way to see Pagosa Springs from every angle. 

No matter which outfitter you choose, rafting the San Juan is one of the best ways to stay cool, see the area’s wild beauty up close, and enjoy an unforgettable Colorado adventure. Just make sure to check current water levels and conditions before heading out, and don’t forget your sunscreen! 

Kayaking: Paddle at Your Pace 

For those who prefer carving their own line through the water, kayaking offers freedom and flow. Depending on the CFS, you can paddle through mellow town sections or tackle technical whitewater challenges. Kayaking is a favorite for locals and travelers alike, especially when the river starts to mellow out mid-summer. Just remember: helmets and life jackets aren’t optional; they’re essentials. 

Tubing: Float Through Town 

There’s nothing quite like tubing and floating in the San Juan River. Just grab a tube, hop in the river, and let the current carry you through town. The best tubing stretch runs from the River Center to Yamaguchi Park, about 2 miles of splash zones, calm pools, and riverside views. If you’re aiming for a relaxed, family-friendly float, the ideal time is late june and all of july, when flows are between 90 and 150 CFS. Anything above 250 CFS can get rowdy fast, with about a 40% flip rate in certain spots. 

Need gear? Head to any of the outfitters mentioned above for rentals and tours. They all make it easy to get on the water with little effort. 

Safety Tip: Kids under 12 are required by law to wear a life jacket, and pets should never be let out along private property stretches of the river. Always check the flow and know your limits. 

Respecting the River 

While the San Juan invites fun, it also demands respect. Much of the shoreline along the river is private property, including the riverbed itself in many stretches. Stay in your raft, kayak, or tube, use designated launch and exit points, and be mindful of others enjoying the water. 

Plan Your Day, Stay the Night 

After a full day on the water, nothing beats coming back to RiverWalk Inn. Our riverside location means you're never far from the action, but you’re also close to a hot tub, sauna, and a good night’s sleep. It’s the perfect place to wind down and plan your next day of summer adventure. Whether you’re rafting into the wild, kayaking through town, or simply floating your cares away, it’s time to dive in and make some waves.
