The one at Longleat looks like incredible fun. I could easily waste a few hours in that. I also noticed they have a traditional low ornamental labyrinth too.

I think one of the reasons mazes are appealing is because it's like a giant puzzle that is fully "interactive" so to speak. And there's a certain mystery to them.

I have heard there is a maize maze not far from me. Cue corny jokes. =P
