We really enjoyed our float. I'm giving it a 4 in comparison to the other float we did on this vacation. The guide was good, but didn't have lots of knowledge about the area or the things we were passing (again in comparison to the other float that we did). But we did enjoy it and I would do it again. It was 8 miles long (the guide told me when I asked) and did seem a bit short...he went through it pretty quickly. The views on the Yellowstone River were beautiful!
