We have three boys (17, 15 and 11). Looking for suggestions on what to do while we're in Colorado. Would be end of July/first of August. Hoping to see the Cardinals play at Mile High Stadium. Unsure what part of Colorado would be our best bet. Would like to go white water rafting for sure. Probably go to Pikes Peak also. We are all up for adventurous activities. But, at the end of the day, would like to return to a comfortable place to relax. So, would also like suggestions on cabins/cottages to stay.
