South Mountain Park - one of the largest municipal parks

South Mountain Park and Preserve in Phoenix covers roughly 16,000 acres (commonly reported as about 16,283 acres) and is frequently cited as the largest municipal park in the United States. The park includes miles of trails, multiple scenic overlooks, and the Dobbins Lookout. The claim that it is the largest municipal park is often repeated in guidebooks and city material, though comparisons depend on how municipal boundaries and park definitions are applied.
