Booked to do this for myself, 17 y/o , friend, her husband and 13 y/o daughter. First of all.... it is definitely an exhausting experience. The 13 y/o didn't make it to the canyon she got too overwhelmed and a bit scared after the swim test. The swim test, yes there is one, no it's not a joke. You are throwing yourself into creek and swimming against current until you flip on your back and then swim to the boat or the side if the creek in 38 degree water. It was very very hard, and a bit scary. The guides do a great job of truly explaining the extent of what the experience can be to give everyone the option to bow out. But you truly can't imagine until you experience it. I am so glad I did the first 2 canyons but I never did the 3rd, by that point I was just DONE, so exhausted and really cold. Definitely layer up good. My drysuit was not dry... probably had some pinholes in the sock part because I had water get in from the beginning of just stepping into the creek but everyone else in my group stayed pretty dry. Every guide was really nice but think ours Neal was the best... because he got us through it and no one fell in... that means alot in my book lol Actually he was really informative, friendly and extremely helpful. Everyone should definitely experience something like this atleast once :)
