We visited Denali last year and had a spectacular time. I have rafted a few times before, but my hubbie had not. I felt he needed a big splash into the fun. We rafted in 38 degree water. This was cooooold. However, we were provided excellent dry suits, that kept the important parts mostly warm, and mostly dry. We had excellent guides, which we tipped very well. We had awesome views, including a rainbow across a canyon, that was too pretty to be real. It was a shorter trip, since it was hubbie's first time, but it was just right, with the rain that began at the close of our trip. I highly suggest this experience.
