Traveling between Denver International Airport (DEN) and Union Station is a common requirement for visitors and locals navigating the Denver metropolitan area. This route connects the primary aviation hub with the city’s historic heart, where travelers find Amtrak, light rail, and bus infrastructure. Understanding the available options ensures a smooth transition, whether you are arriving or departing.
Transportation Options Overview
Several distinct methods exist to complete the journey from the airport to the central rail hub, each with specific benefits regarding speed, cost, and convenience. The primary choice involves balancing direct service against budget considerations, as some solutions offer door-to-door ease while others require transfers. Selecting the right path depends heavily on your luggage, schedule, and comfort with public transit systems. Planning for this leg of your trip typically adds minimal stress to the overall travel experience.
The Ride-Hailing and Taxi Standard
The most straightforward method involves using a rideshare application or hailing a traditional taxi at the designated stands located outside the terminal. This option provides a direct route to Union Station without the need to navigate public schedules, making it ideal for late-night arrivals or groups traveling together. While convenient, this is generally the most expensive choice, with fares subject to traffic conditions and standard metered rates. Expect a drive time of roughly 30 to 45 minutes, depending on congestion on the E-470 bypass or I-25.
Private Car Services
Pre-booked luxury vehicles for a premium experience.
Fixed pricing options available to avoid meter uncertainty.
Meet and greet services inside the terminal for efficiency.
The Regional Transportation District (RTD) Train
For budget-conscious travelers seeking reliability, the RTD A Line offers a frequent and efficient rail link directly connecting the airport to Union Station. This train operates on a dedicated corridor, avoiding road traffic, which often makes it faster than driving during peak hours. The service runs at regular intervals, ensuring you do not spend excessive time waiting on the platform. It represents the sweet spot between cost and speed for the majority of solo travelers.
Key Train Route Details
Public Bus Alternatives
While the train is the recommended rail option, the RTD network also provides bus routes that connect the airport perimeter to various transit centers. These services are useful if you are staying in a neighborhood off the direct rail line, though they generally take longer due to road stops. Travelers with significant luggage may find the bus experience cumbersome, particularly when navigating stairs and multiple stops. Checking the specific route and schedule online beforehand is essential to avoid missed connections.
Driving and Parking Considerations
Self-driving offers flexibility, but requires an understanding of the airport layout and parking costs. If you choose to drive yourself to Union Station, you will navigate south on Peña Boulevard, merging onto I-70 or I-25 depending on your specific exit strategy. Long-term parking at the airport is available, but rates can accumulate if you leave your vehicle for extended periods. Traffic on I-25 can be unpredictable, so always add a buffer to your estimated travel time.
