For those who didn't know, Watership Down exists. I live in England and in fact quite close. I think I was told a while ago that Richard Adams lived there and used to tell his children/grandchildren? stories about rabbits there and they asked him to write a book of them.
3nodding One of my dad's best friends lives there and we were invited to go once. I was so excited to see the real place where the story took place but we couldn't go in the end.
So i'm gonna post the real places where Watership Down took place. I hope this is interesting!
NOTE: These pictures aren't mine. Got them from the internetz.

Apparently this place isn't mentioned in the book but the rabbits would have crossed here.
