Since my visit to Cumbria, Sunkenkirk has to be up there but as I have only visited it once I can really say it is my favourite.
I think that has to go to Adam's Grave near Alton Barnes. When I am stood high up on that mound with the wind bellowing over the down it always gives me a tingling feeling. Of course Rex used to like running around up there also, so it is a special place for me for that reason too.
