We want to take the train from Dublin direct to a city in the west-southwest part of Ireland to rent a car for a few days and drive around the area. We want to see the Cliffs of Moher, Ring of Kerry, etc. that we've read about - ending in Cork where we can fly to London for the next part of our trip.
What city that is reachable by train direct from Dublin would you suggest to start in?
Any suggestions on what to see that might be interesting but doesn't generally make the travel books would also be welcome.
