Six Flags Magic Mountain will extend its lead as the Roller Coaster Capital of the World when the Valencia amusement park adds a 21st coaster to its record-setting lineup while continuing to fend off challenges by rivals edging ever closer to the title.

Six Flags is investing $1 billion for park improvements over the next two years. A new roller coaster is to replace two rides in the Arlington park.

Six Flags Magic Mountain will add to its expansive roller coaster line-up with the debut of a new “first of its kind” coaster in 2026. Magic Mountain currently has 20 roller coasters, more than any other theme park worldwide.
