I can also recommend the Dingle peninsula. We road the bus into Dingle with some school children and I can tell you they were none too happy about "Irish" (gaelic) class. But it is very cool to walk into a pub full of people speaking gaelic and having the bartender switch to his second language - English - to take your order.
