I did Puzzlewood last autumn with two friends (me-late 30s, friend 1-late 40s, friend 2-mid 40s) and a daughter aged about 9.
Sure, the daughter did a Hallowe'en themed trail but us three adults got totally into it and the woods themselves were pretty cool. It's like a big maze and there are some interesting trees and hollows and things.
I suppose it depends if you like walking around outdoors looking at nature.
