Denver Airport (DEN) – Getting to the City from America's Most Remote Major Airport

Denver International Airport sits about 40 km (25 miles) northeast of downtown Denver — it is one of the most distant major airports from its city center in the United States. The A Line commuter rail runs directly from the airport to Union Station (downtown) in 37 minutes for $10.50 (EUR 9.70). A taxi costs $55–$65 (EUR 51–60) and takes 30–45 minutes. Uber and Lyft run $35–$60 (EUR 32–55) depending on demand. A pre-booked private transfer costs $75–$120 (EUR 69–110).

The A Line train is the clear value option — fast, predictable, and cheap. For groups, late-night arrivals, or anyone with heavy luggage, a taxi or pre-booked transfer makes more sense.

DEN is a massive airport with a distinctive white-peaked roof visible from miles away. It has three concourses (A, B, and C) connected to the main terminal (Jeppesen Terminal) by an underground train. After landing, you take the airport train to the main terminal, collect your bags, and head to ground transportation.

The main terminal is well-signed. The A Line train station is on Level 1 (ground level), accessible by escalators from the baggage claim area. Follow signs for "Rail" or "Train to Denver."

The taxi and rideshare pickup is on Level 5 (the upper level of the transit center), also clearly signed from baggage claim. The walk from baggage claim to either option takes about 5–10 minutes.

DEN handles a high volume of passengers, but the terminal is modern and navigation is straightforward.

| Option | Cost (USD) | Cost (EUR) | Time to Union Station | Best for | |--------|-----------|-----------|----------------------|----------| | A Line commuter rail | $10.50 | 9.70 | 37 min | Most travelers | | Pre-booked private transfer | $75–$120 | 69–110 | 30–45 min | Families, groups, comfort | | Taxi | $55–$65 | 51–60 | 30–45 min | Convenience | | Uber / Lyft | $35–$60 | 32–55 | 30–45 min | Flexibility | | SkyRide bus (RTD) | $6.00 | 5.50 | 50–70 min | Budget travelers |

The A Line (University of Colorado A Line) is a commuter rail service operated by RTD. Trains run every 15 minutes during the day and take exactly 37 minutes to reach Union Station. From Union Station, you can walk to LoDo (Lower Downtown) or transfer to light rail, bus, or rideshare for other Denver neighborhoods.

Taxis use meters at DEN. The fare to downtown is fairly consistent at $55–$65 because the route is mostly highway with predictable travel times. There is a $3.50 airport surcharge added to the meter.

Uber and Lyft have a designated pickup on Level 5, Island 5 of the transit center. Fares fluctuate with demand — during ski season weekends and holidays, surge pricing can push rides above taxi rates. During quiet times, fares drop to $35–$45.

| Destination | A Line (USD) | Taxi (USD) | Uber/Lyft (USD) | Transfer (USD) | |-------------|-----------|-----------|-----------------|---------------| | Union Station / LoDo | $10.50 | $55–$65 | $35–$55 | $75–$100 | | Capitol Hill / Colfax | $10.50 + transfer | $55–$70 | $35–$55 | $75–$100 | | Cherry Creek | $10.50 + transfer | $60–$75 | $40–$60 | $80–$110 | | Boulder | N/A | $90–$120 | $70–$100 | $110–$150 | | Ski resorts (Breckenridge, Vail) | N/A | $250–$400 | $200–$350 | $200–$350 |

For destinations beyond downtown Denver, the A Line to Union Station plus a rideshare or light rail for the last leg is often the best value. For ski resort transfers, dedicated shuttle services (like Colorado Mountain Express) often offer better rates than taxis — expect $50–$80 per person to major resorts.

All road-based fares are relatively consistent because most of the route is the E-470 tollway or I-70/I-25, which rarely has severe congestion except during rush hour or major weather events.

The A Line runs until approximately 1:30 AM on weekdays and weekends, with reduced frequency after 10 PM (every 30 minutes instead of 15). If your flight lands before midnight, you can still catch the train.

After the A Line stops running, your options are:

• Taxis: Available 24/7 at the terminal, same metered fares
• Uber/Lyft: Available but with longer wait times (10–20 minutes) and potential surge pricing
• Pre-booked transfer: Your driver waits regardless of time

The A Line allows luggage but does not have dedicated storage areas — you hold your bags or place them in the aisle. With multiple large suitcases, this can be awkward, especially during busy periods.

For families with children, the A Line is manageable if you are traveling light. The train has space for strollers, and kids enjoy the ride. However, if you have car seats, ski equipment, or more than 3–4 large bags, a taxi or transfer is more practical.

Child car seats are not provided by taxis at DEN. Rideshare car-seat options exist but are unreliable. A pre-booked transfer can provide a child seat on request — specify when booking.

For ski trips, the luggage factor is significant. Ski bags, boot bags, and personal luggage for a family quickly exceed what fits in a standard taxi. Book an SUV or van transfer for $100–$130 (EUR 92–120) to downtown, or arrange a dedicated ski resort shuttle.

Taxis: Go to Level 5, Island 1 of the transit center. The taxi line is organized and staffed. Wait times are typically 5–15 minutes.

Uber/Lyft: Go to Level 5, Island 5 of the transit center. The app directs you to the exact pickup spot. A staffed holding area helps coordinate pickups.

Pre-booked transfer: Drivers typically meet you in the main terminal near baggage claim or at a designated curb spot on Level 5. Your confirmation will specify the exact meeting point and driver details.

Take a taxi if: you are in a group of 3–4 (splitting the $55–$65 fare), have moderate luggage, or prefer the simplicity of a metered cab.

Book a private transfer if: you are traveling with a family, have heavy luggage (especially ski gear), need a child seat, or are heading to a destination beyond downtown.

Use Uber/Lyft if: you want flexibility and are traveling during off-peak times when fares are lower.

The 40 km distance from DEN to downtown means the price difference between options is significant — much more than at a close-in airport. For solo travelers, the A Line saves $45–$55 over a taxi. For groups of 3–4, a taxi split four ways is only $14–$16 per person, making it competitive with the train.
