The maze incorporates a treasure hunt that makes sure all corners of the field are visited. You get a map, and a red flag to enable rescues to take place. (They do, frequently!)
There are quite a number of Dead Ends.
We must have walked quite a way in the hour and a half we spent in the field of maize, before finally escaping, victorious after having, led by Andrew and Kate, tracked down all the clues.
There are other attractions at the farm. This year they have a Barrel Train that was enjoyed by all those who tried it.
