Bus Service

Student fees pay for students to have a bus pass each semester. Students receive an RTD College Pass card, which can be used for free bus rides throughout Boulder and the Denver metropolitan area, including rides to Denver International Airport (DIA) and the Eldora Mountain ski area. More route and RTD information.

The Buff Bus provides free transit around the main campus to 30th Street. The Buff Bus operates each day and night throughout the fall and spring semesters when classes are in session. Learn more about the Buff Bus.

Late Night transit operates on its regular route every 15 minutes from 10 pm to midnight on these nights and connects Boulder's main activity centers, downtown, CU, and Twenty Ninth Street.

Many students enjoy biking to campus and around Boulder. Bicycle registration is mandatory at CU. Register your bike at the CU Bike Station just east of the UMC from 9 a.m. to 5 p.m., Monday through Friday. Bring your bike, your student ID, and $10 to register. To learn more about the Bike Program, or find local bike routes, visit Parking and Transportation Services. Don't have a bike? Boulder B-cycle is a community nonprofit formed to implement and operate a bike-share system. Or visit the Environmental Center for information on short-term and semester-long bike rentals.


CU Boulder has launched Zimride, a social network for ridesharing. Zimride is a simple way to find friends, classmates, and co-workers who are going the same way you are. For more information please see Parking and Transportation Services.
