How to get here
The Thunderhill Open takes place at Thunderhill Raceway Park, located just west of I-5 in Northern California.
The track is easily accessed via County Road 306 off Highway 162 and is the single entry point for all attendees — racers, crews, spectators, vendors, and media.
Follow posted event signage on arrival. Plan ahead and arrive only through the main gate.
