  • "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."
  • "I’ve traveled with Pete on 4 river trips, 4 of them covering multiple days. In every case, his professionalism shines and in each case, my experiences have been nothing less than brilliant." - Alan

  • "I think I have been on a half dozen trips with Momentum (and dozens with other river outfitters so I know what I am talking about in this one limited area). Momentum rocks! Absolutely the best in every category. The guides are unbelievable in their knowledge of the surroundings and in their ability to make everyone feel welcome and challenged. The food is first class. Every trip is pure fun from dawn till late night. "
