If the parks claim "Now with 15 coasters, Six Flags Magic Mountain has more than any other theme park on Earth" means as much to you as it does to us, you'll like this place.  This is one of those multi-day theme parks that draws people from all over the world. 

They have plenty of non-coaster activity, by the way.  There are a number of food and shopping opportunities.

Directions:
Take the 101 Freeway south to the 126 Freeway east. Take the 126 Freeway east to the Interstate 5 Freeway south. Exit Magic Mountain Parkway, right at the traffic signal at the bottom of the exit ramp. Proceed along Magic Mountain Parkway to Parking Toll Booths and entrance to Six Flags California.
