This was about our fifth visit to Colorado, and we have seen all those places you listed (which we loved). This visit we went to the Black Canyon of Gunnison National Park, the Great Sands Dunes National Park and Preserve, Zapata Falls, and Castlewood Canyon State Park. The rest of the time was spent visiting family out there. We did bring back two boxes of Palisades peaches. Boy are they yummy!!
