Colorado itinerary

Can someone help me fix these online four day itineraries? We mostly want to see pretty nature spots without having to drive 4-5 hours from each other. We are willing to drive an hour or two though!

Front Range sample: Day 1 Denver breweries + LoDo/RiNo; Day 2 Boulder + Red Rocks; Day 3 Estes Park + RMNP (timed entry); Day 4 Colorado Springs (Garden of the Gods + Pikes Peak).

I-70 sample: Day 1 Vail/drive to Glenwood; Day 2 Hanging Lake + hot springs; Day 3 Aspen + Maroon Bells; Day 4 scenic drive back with stop in Breckenridge.

Southwest sample: Day 1 Durango town; Day 2 Mesa Verde + nearby ruins; Day 3 Million Dollar Highway to Telluride/Ouray; Day 4 Black Canyon
