Quick Answer: The A Line train is cheapest ($10.50) but only goes to Union Station. Rideshare runs $35–$90 depending on surge. Taxis are about $65 flat to downtown. Shared shuttles are $20–$40 but add 30–60 minutes of stops. Private car service is fixed-price, pre-staged, and the only option where someone is already waiting at the curb when you walk out.

The A Line Train — $10.50 and 37 Minutes to Union Station
The RTD A Line commuter rail connects DEN to Denver's Union Station in downtown. It's the cheapest option and it works well — within a specific set of circumstances.
Cost: $10.50 one way. You can buy tickets at platform kiosks or use the RTD mobile app.
Schedule: Every 15 minutes during peak hours (roughly 6:00 AM–7:00 PM weekdays), every 30 minutes evenings and weekends. Last departure from DEN is around 12:30 AM. First train leaves around 3:30 AM.

Travel time: 37 minutes to Union Station with six intermediate stops.
Where it works: Solo travelers with one carry-on bag heading to a downtown hotel within walking distance of Union Station. LoDo, Larimer Square, the Convention Center — all reachable from Union Station on foot or via a short light-rail connection.
Where it doesn't: If you're heading anywhere outside downtown — Cherry Creek, Tech Center, DTC, or any mountain destination — the train gets you to Union Station and then you need a second ride. Two bags plus a ski boot bag on a commuter train at rush hour is manageable but not enjoyable. Groups of four or more with luggage will spend more time wrangling bags than saving money.
Rideshare (Uber/Lyft) — Convenient Until It Isn't
Rideshare is the default for most travelers. Open the app, request a ride, wait. The process is familiar. The pricing and timing at DEN, though, are less predictable than people expect.
Cost: UberX from DEN to downtown Denver: $35–$55 standard. During surge pricing (Friday afternoons, holiday weekends, ski season mornings): $60–$90+. Uber Black: $70–$100+. Airport surcharges are built into the fare.
Wait time: 8–15 minutes from request to pickup during normal hours. During peak periods, wait times can stretch to 20–25 minutes. The rideshare pickup zone is on Level 5, Island 5.

Where it works: Solo travelers or couples heading to a straightforward Denver address, during non-peak hours, with standard luggage.
Where it breaks down:
- Peak pricing — DEN's rideshare surge pricing is aggressive during ski season. A Friday 2:00 PM arrival in January can easily cost more than a private car service.
- Groups — UberXL or Lyft XL fits up to 6 passengers, but luggage capacity is unpredictable. One driver shows up in a Tahoe with plenty of room; the next has a mid-size SUV where four suitcases don't fit.
- Mountain destinations — Most rideshare drivers won't accept trips to Vail, Breckenridge, or Aspen. If they do, the fare is $250–$400+ one way, and the driver may not know the mountain roads.
- No one waiting — You request after landing. The driver heads your way after you request. You wait. With a car service, the vehicle is already there.
Taxi — The Predictable Middle Ground
Taxis at DEN are regulated, metered, and available without an app. The taxi queue is on Level 5, Island 1.
Cost: Flat rate to downtown Denver: ~$65. Metered rates to other destinations vary — Cherry Creek runs about $55, Tech Center about $75–$85. Tip is standard 15–20%.
Wait time: Usually under 5 minutes during business hours. The queue moves steadily.

Where it works: When you want to leave immediately without an app, your phone is dead, or surge pricing makes rideshare absurd. Taxi pricing doesn't change based on demand.
Where it doesn't: Taxis are metered, so heavy traffic means a higher fare (except for the flat-rate downtown corridor). Vehicle quality is inconsistent — you might get a clean sedan or a cab that's seen better decades. No pre-arranged coordination for groups.
Shared Shuttle — Cheap, Slow, and Unpredictable
Several companies run shared shuttle vans from DEN to Denver-area hotels. You book a seat, share the van with other travelers, and the driver makes multiple stops.
Cost: $20–$40 per person to downtown Denver hotels. Mountain destinations (Vail, Breckenridge) run $60–$100 per person.
Wait time: 15–45 minutes. Shuttles operate on schedules, not on-demand. You wait until the van fills or the departure time hits.

Travel time: Downtown Denver: 50–90 minutes (depending on how many stops). Mountain destinations: 3–4+ hours with stops.
Where it works: Budget solo travelers with flexible schedules who don't mind the route. Ski shuttles to specific resorts can be reasonable if you book ahead and the schedule aligns with your arrival.
Where it doesn't: For anyone who values their time. A shared shuttle to downtown Denver that takes 75 minutes (vs. 35 minutes by car) costs you 40 extra minutes to save $20–$30. If you're traveling with a group, the per-person cost adds up fast — four people at $35 each is $140, more than a private car service that takes half the time.
Hotel Shuttle — Free but Limited
Some Denver-area hotels run complimentary airport shuttles. They pick up at the hotel shuttle zones on Level 5.
Cost: Free.
Wait time: 20–40 minutes. Shuttles run on fixed schedules. You call the hotel from the courtesy phone bank or cell phone lot direct line, and they dispatch when the next run departs — not when you call.

Where it works: If you're staying at a hotel that offers the service, you have no luggage emergencies, and you're comfortable waiting. Airport-adjacent hotels (near Tower Road or along I-70) commonly offer shuttles.
Where it doesn't: Downtown Denver hotels rarely offer DEN shuttles due to the distance (25 miles). You're locked into the hotel's schedule, and there's no priority — the shuttle picks up everyone who called before you.
Rental Car — Independence with a Time Tax
All rental car companies at DEN operate from the consolidated Rental Car Center, which is not in the main terminal. You take a shuttle bus from Level 5, Island 4.
Cost: $40–$120+ per day depending on vehicle class, season, and how far ahead you book. Ski season prices spike. Add insurance ($15–$30/day if you need it), gas, and parking at your hotel ($20–$50/night in downtown Denver).
Time from baggage claim to driving: 20–30 minutes minimum. Shuttle wait (5–10 min), ride to Rental Car Center (5 min), counter/check-in (5–15 min), vehicle pickup and inspection.
Where it works: Multi-day trips where you need independent transportation — exploring Colorado, visiting multiple mountain towns, or combining business meetings across the metro area. If you're heading to one destination and back, it's usually more hassle and total cost than it's worth.
Where it doesn't: One-way trips to the mountains and back. After a long day of skiing, the last thing you want is a 2-hour drive on I-70. Winter rentals without all-wheel drive are a liability — Colorado's traction law requires chains or AWD on I-70 during winter storms, and not all rental SUVs are AWD despite looking the part.
Private Car Service — Fixed Price, Pre-Staged, No Variables
A private car service operates differently from every other option on this list. You book in advance, receive a confirmed price, and your chauffeur is at the airport before you land.
Cost: DEN to downtown Denver: typically $90–$140 depending on vehicle class (sedan vs. SUV). DEN to Vail: $350–$500. No surge pricing, no meter, no surprises. The price you're quoted is the price you pay.
Wait time at curb: Zero — if the car service is doing its job. Your chauffeur monitors your flight, adjusts for delays, and is in position when you reach the pickup zone. You walk out, get in, leave.
Where it works:
- Business travel — you need to arrive somewhere on time looking composed, not sweating after a luggage sprint through a shared shuttle van
- Groups — SUVs fit 6 passengers with luggage, Sprinter vans fit 12. One vehicle, one price, everyone together
- Mountain destinations — the driver knows the roads, the vehicle is equipped for conditions, and you relax instead of white-knuckling I-70 for two hours
- Late arrivals — when your flight lands at 11:45 PM and the A Line has stopped running, rideshare availability is thin, and the taxi line is long
- Weddings, events, multi-stop trips — the chauffeur stays with you. No rebooking, no app, no coordination stress
The real difference: Every other option on this list starts after you request it. A private car service starts before you land. Flight tracking, vehicle staging, route planning, and communication protocols are running while you're still in the air. That's the gap — not just the vehicle, but the infrastructure.

Frequently Asked Questions
What's the cheapest way to get from DEN to downtown Denver?
The RTD A Line train is $10.50 one way to Union Station (37 minutes). It runs every 15 minutes during peak hours and every 30 minutes late at night. It's the cheapest option, but you'll need a secondary ride from Union Station to your final destination unless your hotel is in LoDo.
How much does a taxi cost from DEN to downtown Denver?
About $65 flat rate to downtown Denver. The meter may read differently, but most Denver taxi companies offer a flat rate for the DEN-to-downtown corridor. Tip is extra. For destinations outside downtown (like Cherry Creek or the Tech Center), expect $55–$85 metered.
Is Uber or Lyft cheaper than a private car from DEN?
Base pricing is sometimes lower, but DEN rideshare rates include airport surcharges and surge pricing during peak hours. A standard UberX from DEN to downtown runs $35–$55 on a normal day. During ski season Friday afternoons or holiday weekends, surge can push that to $60–$90. Private car service is fixed-price — no surges.
How long does the A Line train take from DEN to Union Station?
37 minutes, with six stops. The train runs every 15 minutes during peak commute hours and every 30 minutes late at night and on weekends. Last train leaves DEN around 12:30 AM. First train departs around 3:30 AM.
Should I rent a car at DEN or use a car service?
If you're staying in Denver or heading to one destination and back, a car service is usually simpler and often comparable in total cost after parking, gas, and insurance. If you need a vehicle for multiple days of independent driving — especially to mountain towns — a rental car makes more sense. The rental car center is a shuttle ride from baggage claim, so budget 20–30 extra minutes.
