World-Class California, Idaho, Arizona, Alaska, and Oregon Rafting & Adventure Travel Vacations
"What just might be the best commercial rafting company in North America. The trips are spectacular beyond description, the guides are the best of the best, the food is incomparable, and the customers are treated like royalty."

We are a small guide owned and operated company offering adventure travel and whitewater rafting in Oregon, California, Idaho, Arizona, Alaska and beyond.

You will enjoy world-class river and adventure travel trips with a handcrafted quality and attention to detail, a focus on friendliness, personal service and comfort, and one of the most experienced (and friendly) guide staff’s in the world.

We offer trips ranging from mild to heart-pounding, from half-day trips to 12-day wilderness adventures, from remote and rarely run expedition-style trips to some of the most comfortable river trips in the world; most are off the beaten path, and all offer incredible scenery.  Our multi-day trips are done with our comfortable and innovative wilderness camping (something we are well known for), lodges, or our unique and award-winning ‘safari-style’ luxury camping.  No matter the place or style, all of our trips are a mix of service, relaxation, excitement, and wild beauty – a chance to step out of civilization for a short time and step into a more simple and uncomplicated life.  Whether you’re a first-timer or an experienced paddler, join us for a river trip like no other.

Recent Guest Testimonials

  • "As a past small businessman, I know how important feedback can be. I don’t think you have too many worries. I’ve been doing trips down rivers for the last 40 years, I pre-date self-bailing boats. Your guides are the hardest working guides I have ever been around and they put more effort in than any other group I have been around. " - Matt
  • "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
  • "I will be travelling with Momentum as often as I can in the future. This is a first rate company and I couldn't have asked for a better experience. This trip changed my perspective on life and my life for the better and it made me realize that I need these outdoor experiences in my life. Thank you, truly, from the bottom of my heart." - Courtney
  • "It far exceeded my expectations, I don't think I can ever take another river trip with another company. You made Zach's 40th celebration absolutely amazing... blew all expectations out of the water. Will definitely return again!" - Melanie
  • "We had an amazing trip down the Main Salmon River with Momentum. We had my Dad's 80th birthday on the river, grandkids, aunts, uncles.....ages 14 to 80 and everyone had a BLAST! The guides were friendly, knowledgeable and cooked great meals. Arriving to camp and having everything set up for you was a pleasure. I have been on many a river trip and they say you are pampered....nothing compared to Momentum! Bar and hors d'oeuvres ready for you as you get off the river, the sun sets and you relax while the guides cook 4-star worthy meals. Sam was a great leader and was able to keep the teens having fun every minute of the trip! Lane, Rick, Derek, Sammie (our kayak guide) Shana, Elsa... everyone was great! Planning another trip next summer with Momentum. (Safari-Style)" - Kelly
