Recent Testimonials

  • "I think you all have done a spectacular job of creating a comfortable yet still authentic wilderness experience. It is amazing what can be provided in the wilderness of Alaska." - Gia
  • "There is not a day, on which I do not restore my batteries for daily ho-hum living in “civilized” conditions, by having my mind wander back to that stretch between the Brabazon and Fairweather Ranges visited earlier this year. The “Tat” was indeed epic, and I say this after having seen much of the world. I was impressed by the logistics but not mentally prepared for the level of gourmet living." - Hans
  • "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
  • "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."
  • "It was a fantastic trip & praise to Momentum for your excellent guides, equipment, food & overall river/camping experience! The cots were unexpectedly comfortable." - Cheri
