Buttonwillow Raceway Park
Two hours up the I-5, and the home track for SoCal club racing. NASA and SCCA run weekends here most of the year. It’s the one people send you to for a first real track day: well kept, easier to read than Big Willow. Open Test Days sign in at 7AM and aren’t for beginners.
Private road course in Kern County; access is through track-day organizers and club events rather than casual drop-in. Configurable layout (~3 mi).
HPDE / open track days, time attack (a SoCal time-attack staple), club racing, and testing, booked via organizers.
Frequent weekend events; see buttonwillowraceway.com for the schedule.
On-site camping available on event weekends (Friday and Saturday nights), plus RV space.
Fall through spring; Central Valley summers are very hot.
Buttonwillow Raceway Park — a 3.1-mile road course in Kern County, central California, opened 1996. The state's southernmost full-length road course. Hosts open track days, club racing, and driving schools across multiple configurations. A regular destination for SoCal track-day groups despite the ~2hr drive from LA.
