The world's largest corn maze in the United States is located in Spring Grove, Illinois, at Richardson Adventure Farm. This maze spans 28 acres with about 9 to 10 miles of trail winding through the corn. It features a complex layout with four smaller mazes, multiple checkpoints, and three bridges to help navigate. The maze is designed with a John Deere theme and is created using GPS-powered seed-planting technology.
While there are other large corn mazes in the US, such as Cool Patch Pumpkins in Dixon, California, which is 40-63 acres at times and had world record status in the past, and Stoney Brook Farms in Minnesota with 110 acres, the official current claim to the world's largest corn maze as recognized at multiple sources is Richardson Adventure Farm in Illinois.
