Directed Parking
All parking at the raceway is directed into the facility by raceway personnel. Directed parking allows for maximum use of space and improved traffic flow into the facility. Please follow the direction of the parking staff as you enter/exit the facility.

Daily RV/Oversized Vehicle Parking
Due to limited space throughout the facility, the raceway recommends that you do not bring RVs and other oversized vehicles on race day. Space will be limited, and the setting-up of awnings and additional space next to the vehicle will not be allowed.

Overnight camping is not allowed without a reserved camping pass. Vehicles entering for the day will be forced to leave the raceway each evening by security personnel and Sonoma County Sheriffs.
