How to Get from Denver to Boulder
Getting to Boulder is incredibly straightforward, with fantastic options to fit any budget, travel style, or desire to deal with traffic. Here’s a breakdown of the best ways to make the short journey.
Driving to Boulder
- Route: The most direct route is US-36 West, a straight shot from Denver to Boulder. For a more scenic drive, consider taking US-6 through Golden and then heading north on CO-93 (Foothills Highway), which offers beautiful views as you approach the city.
- Travel Time: Expect the drive to take 45 to 60 minutes in ideal conditions. Be warned: Denver’s rush hour (roughly 7-9 AM and 4-6 PM) can easily double this time. Plan accordingly!
- Parking: This is a crucial detail! Your best bet is to use the city-owned parking garages downtown, like the ones at 15th & Pearl or 11th & Spruce. They typically cost around $1.25-$2.50 per hour. Parking at Chautauqua Park is very limited and costs $2.50/hour for non-residents during peak season. We highly recommend using the free weekend Park-to-Park shuttle in the summer to avoid the stress.
Taking the Bus to Boulder
- Service: The RTD Flatiron Flyer (specifically the FF1 route) is the gold standard for public transport. It runs frequently from Denver’s Union Station directly to the Downtown Boulder Station, putting you right in the heart of the action.
- Cost & Tickets: A 3-Hour Pass costs about $5.25 each way. For unlimited rides all day, a Regional Day Pass is a great value at around $10.50. You can easily buy tickets using the RTD MyRide app, at ticket vending machines at the station, or with exact cash on the bus.
- Why it’s a great option: It’s affordable, eco-friendly, and lets you completely bypass the stress of traffic and the hunt for parking. Just sit back, relax, and enjoy the view.
Rideshare & Shuttles
- Uber/Lyft: A one-way trip will typically run you $50-$80+, but be aware that prices can surge dramatically during peak hours, events, or bad weather.
- Shuttles: To answer a common question, “is there a shuttle from denver to boulder,” the main shuttle services like Groome Transportation primarily connect Boulder with Denver International Airport (DIA). For travel from downtown Denver, the RTD Flatiron Flyer bus is your best and most direct “shuttle” option.
Is There a Train from Denver to Boulder?
This is a frequent question, and the answer is clear: No, there is currently no direct passenger train service between Denver and Boulder. The RTD B Line commuter rail from Union Station ends in Westminster, which is still a significant distance from Boulder. The bus remains the only direct public transit link.
| Method | Avg. Time | Avg. Cost (One-Way) | Pros | Cons |
|---|---|---|---|---|
| Driving | 45-90 min | $5-$10 (gas) | Ultimate flexibility, can stop along the way | Peak hour traffic, parking can be difficult and costly |
| RTD Bus | 50-70 min | ~$5.25 | Affordable, relaxing, no parking stress | Fixed schedule, less flexible than a car |
| Rideshare | 45-90 min | $50-$80+ | Door-to-door convenience, no parking | Most expensive option, subject to surge pricing |
