This will be our first trip to Breckenridge. We are bringing our 8 and 5 year old boys. We have been told that we should try some rafting. I don't want to do anything to scary because we will have our boys with us. Also we don't want to drive too far because this is a short trip. Any suggestions on a reputable company that I could call to schedule this? Also any suggestions on rivers or areas for beginner rafting?
