Reasonable beginner/intermediate level.
Carry upstream from the rafting outfitters to put in just above a sweet series of waves which are scattered across the wide river.
Some will offer repeat play as long as you are suitably skilled, and come off in control. More will be 'catch-on-the-fly', one-shot play.
A good video showing some of the best parts of the run is available on YouTube: https://youtu.be/FCa0WnJtQDs?t=124
