On weekends most parking lots are open and free on campus, pay attention to the hours of enforcement posted on signs in the parking lots. Click here for parking regulations. We suggest to park in Lot 54 which is a short walk from the Integrated Science Building (aka Gray-Little Hall).
Please note: Parking in the covered garage just south of lot 54 now needs to be paid in advance. It is about $15 for 10 hours. http://parking.ku.edu/parking-garage-changes
