Reserving a Buff Bus

CU Transportation is a Federal Cost Service Center.  This allows us to offer reasonably priced services to those affiliated with CU.  Non-profit groups can also utilize our services.  We offer transportation for wedding events for alumni, faculty and staff. Our services are not available to the general public or other private events not affilited with the University of Colorado. If you are alumni, faculty or staff, use the eligibility form below to begin your inquiry. Email it to BuffBus@colorado.edu.  

To make reservations for bus or other chauffeured transportation complete a Reservation Form. If you have trouble downloading the form, we are happy to fax, email or mail you a copy. After we receive your submitted form we will contact you with confirming information. Bus reservations are not guaranteed until you receive a confirmation. For questions or additional assistance, please call 303-492-6603.

Student Organizations must make reservations in person. Bring a signed Interdepartmental Invoice (IN) with a "Total Cost Not to Exceed" stamp and a complete Parking & Transportation Services Use Form (which can be picked up at Student Finance Office or U.C.S.U. office in the UMC).
