Flight
If you're flying in, the Denver Airport is about an hour and a half away from Colorado Springs. However, depending on which airline you fly on, that will determine which airport is best for you. Colorado Springs Airport is more limited than Denver (ex. Southwest doesn't fly in there).
Travel Note
We understand that Airbnb isn't for everyone, but this will be the cheapest way to stay in Colorado Springs. We have used Airbnb multiple times and have always had great experiences. Also, most of the hotels in the area are kinda pricey. If you need help finding a place to stay, don't hesitate to ask. There are some really great Airbnb rentals in the area and are reasonably priced. Just let us know and we will send some your way!
Hotel
If you're not into Airbnb, here is a hotel that I've found that will be close to our ceremony site. It is about a 20-25 minute drive, the room rates include a free hot breakfast, and there's also an indoor pool!
