We arranged a 1/2 day rafting trip with 6 adults in mid-April. I was a bit worried about being miserable on this trip because of the cool weather (and the cold river temp!). However, the staff outfitted us with splash gear which kept us mostly dry, and the only thing cold about me at the end were my toes! The river was running at class 1 and class 2, which gave us enough of a thrill to be exciting, but not scary enough to freak out the less adventurous group members. The scenery is stunning, the guide was fun and easy going. In warmer weather, I'd love to come back and do a full day trip!
