Welcome to your 5-Day Itinerary to Colorado Springs (without a National Park)
If you're not wanting to venture out and explore the Great Sand Dunes National Park, and would rather stay in town, this is everything I recommend :) Mind you, this is very hiking focused but there are PLENTY of in-town attractions and museums to explore if you please.
Make sure to be well-prepared for hiking in Colorado and it's higher elevation. Read my travel tips for more information!
