Welcome to your 5-Day Itinerary to Colorado Springs (with a National Park!)
Since you have more time to explore, I suggest using 2 of those days to go on a beautiful 2.5 hour drive to the Great Sand Dunes National Park! They have a campground for you to stay at with reservations. You can stay 2 nights in the closest National Park and use the other 2 days to explore everything else in Colorado Springs!
