Below the put in falls (it's easy to put in below them) the river is non-stop III-IV action for two miles, with one rapid verging on V in the middle. Just enough to keep you on your toes. As we lapped this run over the week at different levels I became amazed at how good it is. It's scary the first time because it feels like something major is around every corner that you can't stop above, but over time it's more fun and less stress. Even so on following laps moves are defined enough to remain interesting, there are fun eddies and hidden boofs to hit. Above three meters on the gauge it's very exciting and more class V as a swim would be unpleasant and probably result in a lost kayak. On the other hand it took us just over ten minutes to do the run at higher flows. The Upper Cheakamus is simply a river that words and media can't do justice to; even though it's short and roadside I'd consider it a bucket list run for the pure fun factor.
