Is There a Six Flags Magic Mountain in Arizona?

No. There is no Six Flags Magic Mountain in Arizona.

• Six Flags Magic Mountain is located in Valencia, California (Los Angeles County)—the world's roller-coaster-capital park with 20 coasters.
• Arizona's Six Flags park is Six Flags Hurricane Harbor Phoenix (formerly Wet 'n' Wild Phoenix), a water park in Glendale (Phoenix metro). It has no roller coasters.

Other Arizona Theme Parks

• Castles N' Coasters (Phoenix) – 4 coasters, arcade, mini-golf.

If you want the coaster mecca, head to California. For desert water fun, Arizona's Hurricane Harbor delivers.
