Parking for those coming by car is available on Lot 21 and Lot 23, and a free PU shuttle operates frequently from Lot 23 on weekdays, and also from Lot 21 (download campus map here). After 5 pm, you can also use most other parking lots closer to campus (such as Lot 10, 52, but not Lot 6, 8, 9, 11, and 18). More information on parking is available here. There are also three municipal parking garages, which charge a fee, located conveniently on Hulfish, Spring, and Chambers St. in downtown Princeton.
