1. Best amusement park roller coaster

Six Flags Magic Mountain
26101 Magic Mountain Parkway, Valencia

Whether it's looping 160 feet in the sky or the 70 mph speeds, Six Flags Magic Mountain's Full Throttle is the No. 1 tallest and fastest looping roller coaster in the world.

2. Best theme park thrill ride

Knott's Berry Farm
8039 Beach Blvd., Buena Park

Be warned — the Knott’s Berry Farm Supreme Scream ride, located on the park's boardwalk, is a 45-second ride that hits a top speed of 50 mph as it propels riders 252 feet straight up into the air, where you will experience three seconds of weightlessness before being plummeted back to Earth. We recommend riding this thriller before lunch.
