Located in the East of the Phoenix area, in the Superstition Mountains State Park. This is a somewhat popular hike, though not many continue all the way to the top. Expect to see 20-30 other people on a weekend with a handful at the top.
Although most hiking books will call this hike Siphon Draw, most locals know this hike as Flat Iron. The name comes from the ultimate destination of this hike, which resembles an upside down iron.
