Six Flags Magic Mountain is a theme park located in Valencia, California north of Los Angeles. It opened on Memorial Day weekend on May 30, 1971 as Magic Mountain, by the Newhall Land and Farming Company. In 1979, Six Flags purchased the park and added the name Six Flags to the park’s title. In 2009, 2.5 million visitors visited the park. On July 1, 2011, Magic Mountain broke the world record for having the most roller coasters (18) in a single park with the debut of Green Lantern: First Flight, surpassing previous record-holder Cedar Point in Sandusky, Ohio. As of October, 2011, Six Flags Magic Mountain no longer holds the record for most roller coasters in a single park (since the removal of Deja vu), and will share the record for 17 coasters with Cedar Point… Yesterday I was there, and I like it so much! That was so cool!
