I'd add some dolmens to that list, Trevely Quoit, Lanyon and Chun Quoit. And don't forget the Cheeswring if you're going to the Hurlers. . (I think it's by the Hurlers. . it's been over ten years since I've been to Cornwall.

I may be going to Cornwall later this to end my 'Megalithic Year', and I'll be watching this thread with interest. I know I missed Duloe when I was last there. So that's on me list!
