1. Petaluma Pumpkin Patch, California
This four-acre corn maze is located just north of San Francisco. Navigating your way through the twists and turns of the maze to find its one exit is quite the feat! The two tiny grayish-pink specks deep in the maze are viewing platforms, allowing the adventurers to peek out amid the sea of corn. The exact design of the maze is changed slightly every year, so puzzle-lovers can keep coming back for more. Petaluma Pumpkin Patch also offers a spooky nighttime maze experience.
