Best White Water Rafting in California is in the Sierra

Did you know that over 75% of California’s annual precipitation falls during the winter? A big chunk of that ends up as snow in the Sierra, creating what’s often called the state’s “frozen reservoir.” As spring rolls around and the sun climbs higher in the sky, that snowpack begins to melt—fueling a seasonal transformation. Wildflowers start to bloom. Wildlife stirs from its winter slumber. And most of all creeks, streams, and rivers begin to roar back to life.

While spring is famous for its epic waterfalls, there’s another adrenaline-pumping activity you shouldn’t miss this time of year—white water rafting. In fact, the Sierra Nevada is home to some of the best white water rafting in California. Here are a few spots that are guaranteed to get your heart racing and your stoke level high.

Tuolumne River

Rafting Season: April – September
Peak run-off usually occurs between mid-May and mid-June – intense whitewater experience; a high level of physical fitness required

The Tuolumne River gets its start high in the Sierra, fed by the Lyell and Dana Forks as they converge in Yosemite’s breathtaking Tuolumne Meadows. As the river winds west out of the park, it transforms into a whitewater playground—boasting more than 40 named rapids packed into an 18-mile stretch.

One thing that sets the Tuolumne apart? It’s dam-controlled. That means flows are more consistent and predictable during the summer, making it a reliable choice for thrill-seekers looking to plan ahead.

It’s no surprise the San Francisco Chronicle crowned it the #1 rafting river in California. Want to learn more or book a trip? Head over to Visit Tuolumne’s site for details on outfitters and everything you need to know to hit the water.

Truckee River

Rafting Season: Mid-May – September
Peak run-off usually occurs in April & May – intense whitewater experience; for lazy floats on Truckee starts mid-June through September

Just a few miles northwest of Lake Tahoe flows the iconic Truckee River—the only outlet from what many call the “Jewel of the Sierra.” This winding, scenic river is famous for its world-class trout fishing, especially fly fishing, but that’s just the beginning. It’s also a go-to spot for all kinds of water-based adventures.

Looking for something mellow? Try the classic River Ranch Run. Starting in Tahoe City and ending at River Ranch, this easy-going float features Class I and II rapids—perfect for rafts, kayaks, or just a good old-fashioned inner tube.

If you’re itching for more action, head over to Boca Reservoir. That’s where most of the guided rafting tours begin. You’ll take on 5.5 miles of splashy Class II rapids before dropping into the heart-pumping Class III section near Bronco Creek.

Whether you’re chasing chill vibes or white-knuckle thrills, Truckee delivers the perfect spring or summer adventure to round out your time in the High Sierra.

Kaweah River

Rafting Season: Mid-April – June*
Peak run-off usually occurs around Memorial Day (**free-flowing river* season length and flows may vary)

If you’re looking for raw, untamed adventure, the Kaweah River is as wild as they come. Carving its way out of Sequoia National Park—home to legendary spots like Moro Rock and some of California’s best-kept secrets—this river holds a serious title: the steepest in the lower 48. It drops a jaw-dropping 12,000 feet over just 20 miles!

With no upstream dams, the Kaweah runs on pure snowmelt. That means its flow—and its fury—change with the season. Early and late in the rafting season, you’ll find Class II to III rapids. But come peak flow (typically May through early June), things crank up fast to Class IV and even Class V, offering some of the most intense whitewater in California. As you can from the photo on one of the runs by Mountain Descents.

If you’re road-tripping the Majestic Mountain Loop, the Kaweah River is a great addition for thrill-seekers.

Merced River

Rafting Season: April – early July*
Peak run-off usually occur in mid-May and early June, providing the most thrilling whitewater rafting experiences (**free-flowing river* season length and flows may vary)

Last but definitely not least is the legendary Merced River. It begins gently, winding its way through Yosemite Valley—offering a refreshing way to cool down on a hot summer day. A mellow float near Curry Village is perfect for soaking in the scenery, maybe even catching a glimpse of the stars as twilight sets in.

But once the Merced flows west, beyond the park’s boundaries, things start to heat up. This is where the whitewater action begins. As the river tumbles through glacially carved canyons, it transforms into an adventure playground. Depending on the season, you’ll find Class II to IV rapids, with the biggest thrills coming during peak snowmelt. That’s when the river really swells—pushing paddlers into fast-moving Class IV waters that’ll get your heart racing. And once you’re done plunging the rapids head to the June Bug Café where the local river rats hang for a craft beer and a tasty bite.

Whether you’re looking for a peaceful paddle or a full-on adrenaline rush, the Merced delivers a slice of Sierra magic.
