Starting this September, United Airlines will begin nonstop air service from Dayton International Airport (DAY) to Denver International Airport (DEN). If you’re planning on a trip to Denver, here are some helpful tips to make the most of your time there.

Pack with layers in mind

Denver is the gateway to the Rocky Mountains so you will absolutely want to take advantage of all the great outdoor activities it offers. With frequent fluctuations in weather possible throughout the day, dressing in layers and packing with that in mind will save you from sweating or shivering throughout your stay. And plan on snow anytime between November and February.

Think about visiting off high season

If you want to lower the cost of your stay in Denver, consider visiting in April, May, September, or October. Prices for lodging are a bit lower during these months and the city is a little less crowded. The weather is still ideal during these times of the year, so there isn’t much of a trade off for the potential savings.

You might not need a car

For more potential savings, it might be possible for you to do everything on your Denver to-do list without renting a car or paying high parking fees. Denver has a robust public transit system, including a train from the airport to Denver Union Station, located right in the heart of downtown.

Take time to adjust

There are two aspects to arriving in Denver that might affect you. First, Denver is in Mountain Standard Time, which is two hours behind us in Dayton. Second, and most importantly, some people experience altitude sickness when they get to Denver. They don’t call it the “Mile High City” for nothing – it’s located 5,280 feet above sea level, which is 4,542 feet higher than Dayton.

It’s recommended to stay overnight in Denver before taking on the Rocky Mountains to help get acclimated to the elevation. Other recommendations include getting plenty of water, avoiding or limiting alcohol intake, and taking time to rest.

Enjoy all the Denver has to offer

There is so much to see and do in Colorado’s capital. From outdoor activities to checking out Denver’s huge craft brewery scene to museums, parks, and more – this is one city that can keep you plenty busy. With over 200 mountains visible nearby, it’s also the perfect place to kick back and take in the view.

No matter what you do in Denver, getting there can be a breeze. Fly from DAY for an easy to and through experience.
