Idaho Rafting Trips

The World-Class Whitewater of Idaho's Salmon River and Hells Canyon of the Snake
"I've rafted and kayaked rivers throughout the West. Our 6 days with Momentum on the Main Stem of Idaho's Salmon River was a good as it gets. The guides were experienced, hardworking, and attentive. Momentum's policy of hiring only guides with at least 8 years' experience is unusual, and it clearly is working for them."

  • "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
  • "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
  • "You run the best business and hire the best people I have ever been with on the river. Runner up isn’t even close… Great entrepreneurship, customer service, and execution skills are rare, but you have them all going on inside the same shop. (Safari Style Trip)" - Sean
  • "This was our 6th trip with Pete and Momentum! The quality of the guides remains stellar! Thank you Rebecca, Jeff and Jane, it was great to be in your company. I have been rafting with my friends for 30 years and Momentum always takes EVERYTHING up a notch. The food is gourmet, in fact no desire to go out to dinner after 6 days on the river because we knew nothing would compare in quality!!"
  • "Never before have I had every expectation met, and, once met, utterly surpassed to the point of obliteration. Maybe someday I’ll get to slide down the gravity well of a black hole. Until then, there’s Momentum… The guides on our trip embodied a quiet confidence and calm competence that was infectious. Never once did I feel endangered, even beneath my kayak in the middle of a rapid– it happens, and I enjoyed the ride… Momentum guides could lead a one-way expedition to Mars, and I’d sign up tomorrow. They also have some great late-night stories– and the night skies have never been so clear to my jaded eyes. The other guests on our trip were equally amazing. Between the guides and the guests, I have never been surrounded by so many kindred spirits. We were all there for a true time-of-our-lives, guides and guests alike. Once our child is barely old enough, we’re absolutely inflicting him on some folks. The brochure proclaims gourmet meals in the wilds of, in our case, Idaho. “Gourmet” does not adequately describe the effort and attention given to these meals. To get off an already amazing day on the river to an already prepared spread of brie and crackers was mind-blowing. Every single meal, breakfast lunch or dinner, was nutritious and deeply soul-satisfying. I was enabled to make the best sandwich I have ever made for myself beside a creek across from an abandoned mine trail. I took photos of that sandwich. These guides truly do love food and sharing their love of cooking as much as they love sharing their love of nature. I cannot recommend Momentum River Expeditions more highly. I’m not naive enough to believe that I’ve made friends for life on this trip, but I can honestly say that I met people with whom I would want to be friends with for the rest of my life. "
