Describe a place: The Giant's Causeway

In this photograph we can see a beautiful scenery from Northern Ireland, which is called the Giant's Causeway. This place was formed a long ago, it's made of lava which cooled and formed hexagonal blocks.
It seems to be a lonely place because it's in the "middle" of the sea and, it also seems to be a difficult place to reach, I believe this because of the structure (hexagonal blocks) of this nature site.
This place is commonly known as an important English icon, that's why millions of tourists visit this zone every year. Personally, I haven't got the occasion to go there, but I hope to visit it as soon as possible as I think that it is a peaceful place to go and relax.
