Tippy was a great guide and very knowledgeable about Clear Creek and the history of the area. The beginner's trip is just that, designed for beginners. We had our 8,10 and 12 year old boys with us. They were trepid at first but now cannot wait to go again. I would highly recommend if you have never gone before or are with younger kids. My wife and I have gone on more challenging waters but this was a perfect way to introduce the kids to white water rafting.
We were fortunate to see all kinds of wildlife including Big Horn Sheep, all kinds of birds (hummingbird, King Fisher, gold Finch I think, and others). I was a little hesitant being so close to I-70 but it was not an issue or much of an impediment to the views.
Again, we had an awesome trip and can't wait to get back!
