With a lot of asphalt and not much shade, hats and sunscreen are essential in the Southern California sun at Knott's. Layered clothing is helpful in the cool mornings and warmer afternoons. Bring something to secure your hat while on the faster rides, or wear one you can stuff into a pocket. Please note that their dress code is strictly enforced: shoes, shirts or blouses are required at all times. Profanity and pictures of illegal substances on clothing are not allowed.
