CO Springs was just named as a Top 10 city for recent college grads (Denver also made the list). Part of the reason is the exapanding downtown (as my 25 year old AF Lt said when he returned home last year, Springs is now cool). And the new expansion is south of the old downtown. So hit downtown for some good food and relaxation. There's
White Pie for excellent pizza.
COATI is a cool new food warehouse marketplace. And we have a beer garden now there (your daughter can enjoy non-alcoholic drinks and good food trucks) -
The Garden. These are all within walking distance.
Bingo Burger is the older downtown is the best burger in the area and locally owned.
As mentioned above, Garden of the Gods is a must-see - stop at the visitors' center for a good film and then find a good hike. It's a Top 50 site in the US.
If you have a day free, a trip to Breckenridge is fun. Cool ski town about 2 hours away. Park and walk around. Good food up there. And if you go the back route through Woodland Park, the drive will sell you on CO. If she skis or wants to, cadets can get an Epic Ski Pass for about $125 (it includes Breck and other resorts - where day passes cost $200). Plus she can rent skis and equipment cheaply from the Academy.
Manitou Springs is a cool small town to walk through, play a few games at an old arcade, have some food, and collect natural springs water. It borders the Springs.
Old Colorado City is fun to see as well, it's on the way to Manitou. Good BBQ there = Front Range BBQ, and locally owned. The Springs is full of chains but we have better locally owned places.
If you want a day hike nearby, Google Spruce Mountain. It's about a 15 minute drive, but a beautiful easy/moderate hike either up the mountain or in the grasslands. Then hit the small town of Palmer Lake for some wings or lunch.
I don't know where you're coming from but prep for the elevation - always have water with you and hydrate.
Good luck. PM me if you have questions.
Edit: Great new restaurant:
