Flow AK was a peak experience of a long trip around this region of Alaska, and is not to be missed. I wanted a day of whitewater rafting, did the reddit research and chose Sixmile over Nenana in Denali, then found Flow AK, and couldn't be happier how it worked out. The owners, operators, and guides are all top notch, as is the river, and they combine for an entertaining, exciting, easy and unforgettable experience. The staff knows a lot about the river and rapids and the town, including a lot of history. They're extremely talented, communicative, and safe paddlers that will get your body pumping with adrenaline and soaked from head to toe while maintaining total control. It does help to show up with an ability to swim, knowledge of how a paddle works, and an adventurous attitude, but Flow AK has created an all-inclusive, very accessible, and great team experience, and they do everything the right way, from equipment, safety, training, and customer interaction. The half day, 3 canyon trip wasn't cheap, but you get what you pay for and these guys deliver everything you could possibly want at the highest level, plus the river/canyon is very pretty in the summer. Absolutely worth it read more
