Recent Testimonials

  • "Pete, although I filled out your survey form following our trip, my husband and I want to personally thank you for a great trip. What really made the trip special was lead guide, Andy. He greeted us the moment we stepped out of our car at the put-in and from that point on he provided calm, mature leadership throughout the trip. Andy worked non-stop to make sure the group had everything we needed even when the weather was harsh. You should rest assured that your guests are well taken care of with Andy. We only wish you could do more raft supported kayak trips with your staff and the DeRiemer. And thank you Pete for providing an opportunity for us to explore an absolutely beautiful place in comfort. We appreciate the logistic challenges you face when planning this trip."
  • "In July 2018, my best friend and I joined Momentum and the DeRiemers for a 6 day, 5 night raft supported kayak trip down the Main Salmon River. It was our first time paddling western whitewater and we couldn't have asked for a better introduction! The Momentum Guides and DeRiemer Instructors are top-notch. All were highly skilled on the river and very warm and welcoming. The Momentum guides did an excellent job of setting up comfy camps each night and their cooking can't be beat- seriously, the food was outstanding! An extra thank you to Andy for patiently showing me the basics of fly fishing, it was my first time trying it and a highlight of the trip for me. Rafters and hard boaters, if you are looking to get away from it all without having to deal with the often challenging backcountry logistics this is the way to go. Thank you all for a great week in Idaho!" - Donna Morgan
