If you go down to Colorado Springs on a day with no show to get back to, you\'d have no problem hitting both Pikes Peak Cog Rail & Garden of the Gods the same day. If you have extra time, Manitou Springs has a nice town center with quaint shops to walk around.
Glad I could be helpful with some ideas. In 2011, we took our 3 adult children, their spouse & significant other, our granddaughter and my brother-in-law also joined us, to see Furthur at Red Rocks. We spent a few days down in Colorado Springs before moving up to Evergreen for the days of the shows. What I shared was pretty much our itinerary with the kids. We had a great time!
If you ever get back to CO and like to explore, Durango is a beautiful area.
Counting down days till Red Rocks & Fall Tour! Have a great time!
