1. Hever Castle’s Mazes, Kent
This fourteenth century castle is home to two mazes. Yew Maze is your classic hedge-lined adventure, but if you’re after a maze with a difference, Hever Castle’s design also necessitates towels and a change of clothes. The fiendish (and aptly named) Water Maze is located on Sixteen Acre Island, and consists of a series of concentric stepping stone walkways that hover over water. Tread with caution, as some of the stones tilt, prompting jets of water to shoot out (hence the need for towels). Few maze-goers succeed in reaching the stone grotto in the centre without receiving a good dousing – maybe save this one for a hot day.
