Klamath River Rafting

Oregon and Northern California's Klamath River

We are a small guide owned and operated company offering whitewater rafting on the beautiful Klamath River – from mellow to heart-pounding, from Half-day excursions to Multi-day wilderness vacations. The Klamath River is the second largest in California and features more than 180 miles of premier whitewater rafting.

With its origin located near Crater Lake National Park in Oregon, the Klamath River carves out a beautiful and diverse river canyon through one of the most unique geological regions on Earth.  It journeys through the ancient lava flows of the Western Cascades, the cool granite of the Klamath-Siskiyou Mountains and finally through the lush Coast Range of Northern California.

The name “Klamath” means “swiftness” in Chinook, and swift is a perfect description of our Upper Klamath Rafting Trips.  It is our most popular day trip and is also the home of our unique 2-day Safari Trip. The Upper ‘K’ offers by far the most exciting summer rafting on the entire west coast.  It’s fun, addictive, and draws first-time boaters and world-class paddlers alike.  This run features more than 30 rapids ranging from Class III to IV+, including two rapids each over a football field long.

Our Lower Klamath down-river trips take you through the most scenic and secluded portions of the rugged Siskiyou Mountains.  This portion of the river features fun, splashy whitewater (even more exciting in kayaks), sandy beaches, amazing swimming holes and a staggering amount of wildlife.  Also one the finest side hikes in the west – the rainforest setting of Ukonom Falls.  It is a perfect river for families, beginners and relaxed adventurers.

  • "There is no way this trip could have been any better and it will be the standard to which all future river trips will be compared. Your guides are true professionals, incredibly hard working, and just plain great people. The meal/camping situation was astoundingly good, especially given the remoteness and duration of the trip. And of course the scenery was mind-blowing, and the itinerary (loved the layover days) allowed for maximum enjoyment. THANK YOU to everyone at Momentum for showing people like me, who could never visit places like this on my own." - James

  • "The Best – Our family has been on two rafting trips with Momentum, the Klamath and the Rogue, and they were really first rate. The guides are very experienced and great company, the food is excellent, and they make sure you have a wonderful ride without compromising safety in any way. They go the extra mile on everything e.g. providing gluten free food for one of our party, sending out a guide early in the morning to get the best camping sites, playing games with the kids in the evenings and so on. An extra notch above any other rafting company we have been with. Highly recommended."
  • "Flawless! – Couldn’t imagine a better run trip from A-Z. Loved the guides and the vibe surrounding the entire trip. If I’m ever looking to do another trip I will reach out to Momentum to go with them or even for advice on other companies if they don’t run that area…they are just great people."
