Thanks a lot for all the responses! Although I would really like to go up and see things like the Giant's Causeway and the Ulster Folk Park, I don't think we will be going to the North at all. We figure that we will already have a hard enough time trying to see all the stuff on the west coast in 2 weeks!
Alison- We just saw that thing on PBS, "In Search of Ancient Ireland" and it showed Skellig Michael. It looks really neat, but as soon as my mom saw that really steep rock jutting out of the water, she said, "we are not going there!" (I guess she is getting a bit of vertigo just thinking about it!) Maybe we'll just leave her in a nearby pub and head over there!
Declan - Thanks so much for that link! I has been very helpful. My dad and I are hecka stoked to find out that there is surfing in Lahinch. (We'll have to consider bringing our surfboards and wetsuits.)
Thanks again! All of your messages have been very helpful.
