The closest airport is Burbank (BUR), with train service to Camarillo. Driving will take you about an hour. Los Angeles (LAX) is the other option. From there, it is a 90-minute drive to Camarillo. There is also a shuttle service from LAX to Camarillo, run by Roadrunner.
Unfortunately, hotels are not within walking distance to campus, so alternative transportation will be required after you arrive. For those driving to campus, parking is available in Parking Lot A10, behind Lindero Hall.
