This service of the Regional Transportation District (RTD) runs hourly between roughly 6:00 a.m. and midnight; travel time to Boulder is approximately 55-75 minutes, depending on time of day and weather.
Official visitors include researchers, professionals, and students invited to participate in our activities. Public visitors, please see below.

Bus fare information (all buses require exact change or EcoPass)
For employees and official visitors, UCAR provides scheduled service between our three Boulder campuses and major bus lines. There is no shuttle service to the Broomfield Research Aviation Facility.
All our shuttles have bike racks.
Blue bicycles are available at FL2 and CG1 for short-term use by UCAR and NCAR employees and official visitors. Borrow one to travel between campuses, run errands, or just get a little exercise during your lunch break.
UCAR is a co-sponsor of Boulder B-cycle, a community nonprofit organization whose bike sharing stations can be found at Center Green, the Foothills Lab, and across Boulder. Use a credit card at any B-cycle station to purchase short-term access, or sign up online for 24-hour, 7-day, or annual access.
