Quick Answer
The best way for most travelers to get from Denver Airport (DEN) to the 16th Street Mall is by taking the RTD A-Line commuter train. It takes 37 minutes, costs a fixed $10.50 for a one-way ticket, and delivers you directly to Denver Union Station, just a short walk or free shuttle ride from the mall. It's fast, affordable, reliable, and avoids traffic.
Train: The RTD A-Line (The Top Recommendation)
The University of Colorado A-Line is a dedicated commuter rail service connecting Denver Airport (DEN) directly to the heart of downtown at Union Station. It is overwhelmingly the best choice for solo travelers, couples, and families seeking a balance of speed, cost, and convenience.
Why It's the Best Choice:
- Traffic-Proof: Runs on a dedicated rail line, unaffected by I-70 or I-25 congestion.
- Predictable Timing: A consistent 37-minute journey.
- Central Arrival: Union Station is a major hub for local buses, light rail, and the free 16th Street Mall shuttle.
- Excellent Value: $10.50 provides a premium, comfortable transit experience.
Step-by-Step Guide:
- Find the Station: After collecting baggage, follow clear signs for "Transit Center" or "Train to City" to Level 1 of the terminal.
- Purchase a Ticket: Buy a one-way ticket ($10.50) from the RTD vending machines or via the RTD Mobile Ticket app. The Airport Fare is automatically selected.
- Board the Train: Trains depart every 15 minutes during peak times and every 30 minutes off-peak, from ~3:00 AM to 1:00 AM.
- Ride to Union Station: Enjoy the views of the plains and downtown skyline. The train makes several stops, but Union Station is the final downtown stop.
- Walk to the Mall: Exit Union Station onto 17th Street, walk one block south to 16th Street, and you're on the mall. For the free MallRide, turn right (east) on 16th Street.
Key Features & Tips:
Luggage: Ample overhead racks and dedicated luggage areas in each car.
Wi-Fi & Outlets: Free Wi-Fi and power outlets are available at every seat.
Safety & Security: The train and stations are well-lit, monitored, and patrolled by transit security. It's considered very safe, even at night.
Is Flying an Option? (Spoiler: No)
Unlike some international destinations with close secondary airports, flying is not a viable option for travel from Denver Airport to downtown Denver. Denver International Airport (DEN) is the sole major commercial airport serving the region.
Why This Section Exists (For Perspective):
Travelers from other countries might wonder about short “connector flights.” In Denver's case, this doesn't apply. The "door-to-door" time for a theoretical flight would be vastly longer than the A-Line train when you factor in:
- Travel from DEN's terminal to a hypothetical downtown airfield (non-existent).
- Security, boarding, and actual flight time.
- Deplaning and ground transport from the airfield to the mall.
Verdict: The A-Line train effectively serves as Denver's high-speed, ground-based “airport connector.” Do not consider air travel for this route.
Bus & Shared Shuttle Services (The Budget Options)
Regional bus services offer the lowest cash price but trade off speed and direct convenience. There are two main types: public transit buses and private shared-ride shuttles.
1. RTD Public Buses (The Cheapest)
- Route AF (SkyRide): A dedicated airport bus to downtown. Travel time is 55-70+ minutes depending on traffic. Costs $10.50.
- Route 169X (Peak Hours): An express bus during weekday rush hours. Slightly faster than Route AF.
- Where to Catch: Both depart from the DEN Transit Center on Level 1.
- Best For: Extreme budget travelers, those going to specific stops along the bus route not served by the train.
2. Private Shared-Ride Shuttles (Like SuperShuttle)
Companies offer door-to-door shared van service. You book in advance or at counters in the terminal.
- Cost: Typically $30-$50 per person to downtown. Often more expensive than a train, but delivers to your hotel.
- Travel Time: Highly variable (60-90+ minutes), as the van makes multiple stops to drop off other passengers.
- Best For: Travelers going to a hotel not near Union Station, who want a direct drop-off but don't want to pay for a private taxi.
Comparison Tip: For $10.50, the A-Line train is almost always a better choice than both bus options, offering a faster, more comfortable, and more reliable journey.
Taxi, Rideshare & Private Transport (Door-to-Door Premium)
For direct, private transportation from the airport curb to your downtown hotel, taxis and app-based rideshares are available 24/7.
Cost & Pickup Details:
- Flat Taxi Fare to Downtown: The approximate set fare from DEN to the downtown/Central Business District is $55 - $70, plus tip. Confirm the flat rate with the driver before departure.
- Rideshare (Uber/Lyft): Prices are dynamic. Expect to pay $45 - $80+ for UberX or Lyft Standard, depending on demand. UberXL/Lyft XL for groups costs more.
- Pickup Locations:
- Taxis: Located on Level 5, Island 5, outside all terminals.
- Rideshares: Follow signs to “Ride App Pickup” on Level 5, Island 4. You must use the app to request and meet your driver.
When to Choose This Option:
- Traveling in a group of 3-4 people (splitting the fare makes it competitive).
- You have an excessive amount of luggage.
- You arrive after the A-Line has stopped for the night (post-1:00 AM).
- You require door-to-door service due to mobility issues.
Warning: This is the most expensive option by far, often 4-7 times the cost of the A-Line train, and is subject to heavy traffic delays during rush hour.

Purchasing Tickets:
A-Line & Bus: Purchase at airport vending machines (credit/debit/cash) or via the official RTD Mobile Ticket app. The airport fare is distinct from local fares.
Tip: If you plan on using RTD multiple times in a day, consider a $10.50 Local Day Pass (purchased after the airport trip) or a $6 Regional Day Pass for unlimited travel on the day you arrive.
Traveler Experience & Local Tips
Beyond schedules and fares, these practical tips from frequent travelers will make your journey smoother.
Essential Advice for a Smooth Trip:
- Download the RTD App Before You Land: Have the RTD Mobile Ticket app ready. You can buy and activate your A-Line ticket as you walk to the platform, avoiding lines at machines.
- Denver's Altitude & Weather: You've landed at 5,280 feet. Stay hydrated. In winter, the train is far more reliable than driving in snowstorms. Check RTD Service Alerts for any weather-related delays.
- Navigating Union Station: It's a bustling hub. Follow signs for "16th Street" or "Transit Center" to exit towards the mall. The iconic "Travel by Train" sign is a great meeting spot.
- The Free MallRide is Your Friend: Once on 16th Street, the electric, hybrid shuttle buses run continuously from Union Station (at Wewatta) to Civic Center Station, stopping every block. Use it to quickly get to your hotel or a specific mall restaurant.
- For Large or Awkward Luggage: The A-Line train has ample space, but if you have ski/snowboard bags or oversized items, try to board at less crowded cars near the ends of the platform. Taxis/rideshare are easier for massive gear.
- Returning to the Airport: Allow at least 60 minutes total from downtown to your airport gate via the A-Line: 10-min walk to Union Station, 37-min train ride, and at least 15 minutes for airport security. Trains are punctual; plan to take one earlier than you think you need.
FAQs: Getting from Denver Airport to Downtown
Is there a direct train from Denver Airport to 16th Street Mall?
Yes, the RTD A-Line train offers a direct, non-stop rail connection from Denver Airport (DEN) to Union Station in Downtown Denver. From Union Station, the 16th Street Mall is just a short walk or a free MallRide shuttle ride away.
What is the cheapest way to get from Denver Airport to downtown?
The cheapest option is the RTD public bus (Route AF or 169X during peak hours), costing only $10.50. However, the best value for most travelers is the RTD A-Line train ($10.50), offering a superior blend of speed, reliability, and direct downtown access for the same price as the bus.
How long is the train ride from Denver Airport to Union Station?
The RTD A-Line train ride takes approximately 37 minutes from Denver Airport Station to Denver Union Station, with no traffic delays. Trains depart every 15-30 minutes from approximately 3:00 AM to 1:00 AM daily.
What if my flight arrives very late at night or early in the morning?
The A-Line train does not run between about 1:00 AM and 3:00 AM. For late-night arrivals, your only public transit option is the RTD Route 145 night bus (schedule varies). More reliable options include taxis, rideshares (Uber/Lyft), or pre-booking a private shuttle, though these are significantly more expensive.
Is the train or a taxi better for a family with lots of luggage?
This depends: The A-Line train has dedicated luggage racks and space, is excellent for 1-2 bags per person, and is very cost-effective for families. A taxi or rideshare is more convenient for 3+ people with multiple large suitcases, offering door-to-door service, but costs 4-6 times more than train tickets for the family.
Where do I buy a ticket for the A-Line train at the airport?
You can purchase tickets at vending machines located on the transit level (Level 1) of the Denver Airport Terminal, just outside the train platform entrance. The machines accept credit/debit cards and cash. You can also use the RTD Mobile Ticket app.
How do I get from Union Station to the 16th Street Mall?
It's an easy 5-10 minute walk southeast from Union Station. Alternatively, catch the free MallRide shuttle on 16th Street at Wewatta Street (just outside the station). The electric shuttle runs the entire length of the pedestrian mall every few minutes.
Is flying to a different airport faster for reaching 16th Street Mall?
No. Denver International Airport (DEN) is the primary airport serving the city. The concept of a short "shuttle flight" to a downtown airport doesn't apply here. The A-Line train from DEN is the fastest and most efficient public transit link to downtown Denver and the 16th Street Mall.
