    Boulder Transportation

    Arriving by Air

    Denver International Airport is the closest major airport to Boulder and is located approximately 45 minutes east (depending on time of day and traffic). For detailed information about Denver International Airport, please visit Options for getting to and from the airport include:

    Shuttle Services
    SuperShuttle and Green Ride Boulder will take guests directly to many of Boulder's hotels or other locations. Please see their websites for rates and schedules.

    RTD Bus
    RTD operates a bus from DIA to Boulder (Route AB) that makes several convenient stops in Boulder. Buses leave approximately every 60 minutes from the airport. The schedule can be found on RTD's website (select route AB). Tickets are paid directly to the driver upon boarding the bus (cash and exact change only). This is a more economical option, with one-way tickets costing $13. RTD has an information booth on the baggage claim level of the Main Terminal. The trip takes approximately 1.5 hours.

    Driving to Boulder from DIA
    Take Pena Boulevard and merge onto I-70 west. Take I-70 to I-270 west. Continue onto Highway 36, which will take you to the east side of Boulder. This route is easy, free of tolls and takes about an hour during non-peak traffic hours.

    While it is not common for passengers to travel from DIA to Boulder via taxi, the fare would be $88.57 should you wish to do so.

    Public Transit in Boulder

    The Regional Transportation District (RTD) bus system services just about every corner of Boulder. The main downtown bus station, the Boulder Transit Center, is located at 14th and Walnut, with in-town routes serving Boulder and regional routes serving nearby destinations including Denver. 

    Boulder's Community Transit Network (CTN) also provides bus service for Boulder with the easy-to-ride HOP, HOP2, SKIP, JUMP, BOUND, DASH, STAMPEDE and BOLT routes. The HOP's circuit, in particular, is a very useful shuttle-like service for meeting attendees traveling from meetings sites to popular locations including downtown, the Twenty Ninth Street shopping area and the University of Colorado campus.
