The unidentified family - two parents and two children - struggled to find a way out of the 7-acre maze at the Connors Farm in Danvers, Massachusetts when night was falling.
Panicking, they called local police at 6.32pm. An officer soon arrived and began searching for them along with farm manager Ritchie Potter, reports the Danvers Herald.
Potter said: "There is no wire or fence around the maze, so if they really want or need to get out, all they have to do is listen for the sound of traffic. They can always make their way through the corn rows to the road."
The family were found 25 feet from the street.
The farm's owner Bob Connor added: "They were a really nice family. We offered for them to come back and try the maze again, but I think they had enough."
