Travel Info

Getting to Boulder from Denver International Airport (DIA)

Bus: (Probably the easiest and cheapest way)

  • AB Bus (local bus route) will take you from DIA to the Boulder Transit Center (was $10.50 each way, check website for current cost, pay stations at DIA and the Transit Center). The Transit Center (basically bus station) is just one block south of Pearl Street. You can look up the schedule for the AB bus here.
    • To select the schedule heading west from the airport to Boulder, select “Westbound” and to select the schedule heading east from Boulder to the airport, select “Eastbound”. Heading into Boulder, you most likely want to get off at the Boulder Transit Center stop, but there are a few stops in Boulder before that. Heading back out to the airport, you’re going all the way to the Denver Airport Station.
    • They have plenty of room to put suitcases and will put them on / take them off for you!

Taxi Services:

  • Lyft or Uber are always options for travel, but depending on the time of day, could run you anywhere from 50-100 dollars each way.
  • Taxi from the airport is also an option, but likely ~$100 each way. If you wish to get a taxi from Boulder Transit Center to the hotel, the local taxi number is 303 777 7777. (As a warning, the operator refuses to acknowledge the existence of Boulder Transit Center nor a bus station, so give them the nearest corner, 15th & Walnut, this is the north east corner of the block, opposite the Post Office).
  • Super Shuttle or Green Ride from the airport direct to your hotel (about $40-80 each way)

Car: It’s a 45-min drive from DIA to Boulder, there is no need to take a toll road. Basic directions:

  • From Denver International Airport, (8500 Peña Boulevard, Denver, Colorado) head South (.05 miles) and take the ramp onto Peña Blvd (11.4 miles)
  • Merge onto I-70 W (4.6 miles)
  • Slight right onto I-270 W (signs for Fort Collins)(5.8 miles)
  • Continue (same road, different name) onto US-36 W (20 miles)
  • As you enter Boulder on the US-36 (when the speed limit drops) you’ll come to a set of traffic lights (junction with Colorado Avenue). Go straight on and the Millennium hotel is on your left before you reach the next set of traffic lights, there’s a crossing you can take across the central reservation.
  • Here’s a Google Map.
