Travel Information


The closest airport to Boulder is Denver International Airport (DEN), which is approximately 45 miles from Boulder.
If you do not live near a hub airport, your best option for getting a non-stop flight to Denver is on United, Frontier, or Southwest airlines

We highly recommend that you wear a mask at the airport and on your flights prior to arrival, as this will lessen the probability that you fall ill during the workshop.

Ground Transportation

There are several options to get to Boulder from the airport:

  • RTD Bus service, Skyride AB1 Bus is $10.50 each way. Fares can be paid in cash on the bus (they will not make change on the bus, so make sure you have $10.50 or $11), or with RTD's mobile ticketing app. Optionally, a $10.50 day pass can be purchased on the bus or through the app if you plan to make additional bus trips in Boulder. The bus leaves once an hour to Boulder (see its schedule here). To get to Denver Airport Station, when you exit the aircraft, follow signs for baggage claim or the transit center. You will need to board the airport tram to get to Jeppesen Terminal where baggage claim and ground transportation is located. Follow signs to the Transit Center and proceed to the south exit on level 5 (look for the large American flag), exit the terminal through the sliding glass doors and take the escalator located in the center of the plaza down to level 1. The AB1 bus terminates at the Boulder Downtown Station, which is less than five blocks from the St. Julien (walk west down Walnut St until you come to the St Julien entrance; see map here). We highly recommend taking the AB1 bus due to its cost and convenience. 
    (NOTE: there is a train from the airport called the A Line, but it does NOT go to Boulder. It only goes to downtown Denver. Do not take it if you want to go directly to Boulder.)
  • Eightblack Airport Shuttle is $55 each way to the hotel, with additional passengers in the same group being $30 each. There is also a $4 fuel surcharge per group (or for a single passenger).
  • Taxis cost $89.03 for a one way trip.
  • Car rentals are available at the airport.
  • Ride hailing services such as Lyft and Uber are available. Prices range from $60 to $195.

Linked are driving directions for taking the E-470 Tollway ($8), or I-70 from the airport to the hotel. The tollroad can be much quicker because it has less traffic than I-70. Most rental car companies have toll passes in their rental cars so toll charges will be paid through the rental agencies, often with a significant surcharge.
