I have just returned from traveling through Ireland. What an amazingly beautiful country. These trees are fairly well known, at least by photographers, who seek them out. We learned of the "dark hedges" from the proprietors of a darling bed and breakfast in Portrush, Northern Ireland. These are 300 year old beech trees that have grown into a canopy over the road. It is AMAZING. Hopefully this image will give you a sense of this magical creation of nature.
