Six Flags Magic Mountain is one of the largest amusement parks in the world.  The range of coasters on offer here is simply mind-blowing.  From the revolutionaly Fourth Dimension coaster, 'X', to one of the most intense hyper coasters ever built, Goliath, Magic Mountain has much to offer.  The park is let down, however, by reliability issues  - often resulting in many closed rides and attractions.  Despite it's excellent coaster selection, many people agree that the reliability issues that Six Flags Magic Mountain has prevents it from becoming one of the best parks in the world.
