My son's want me to take them to King Arthur's Castle ruins over on the West Coast. We are staying in London, so I really would rather not hire a care if possible. Is there a train and what routing would I take to get there? How far from the station is the ruins. Any information would be appreciated.

Also, since I know a lot of knowledgeable Irish or Ireland travelers frequent this site and they have not put in a Gold Circle thread yet, any help on this one?

What would be the best routing to get from actually Gorey, Ireland to The Giants Causeway up north. I have been to the station in Gorey before and all the guy there knows is that you go up to Dublin and change trains there. He was not much help. Any ideas out there?
