Have you ever been in a giant maze?

Mazes have been built with walls and rooms, with hedges, turf, or with paving stones of contrasting colors or designs, or in fields of crops such as corn or, indeed, maize. Maize mazes can be very large; they are usually only kept for one growing season, so they can be different every year, and are promoted as seasonal tourist attractions. Players enter at one spot, and exit at another, or the idea may be to reach a certain spot in the maze.
