Olivia, How long are you there and how are you getting around? I picked up a hire car in Dublin and drove around Ireland for 10 days. But just watch hire care conditions. They didn't like taking cars from Dublin into Northern Ireland, so I didn't get there. If you have the time and are not restricted, I found New Grange a fascinating place. http://www.knowth.com/newgrange.htm I'm sure other will have their favourites. Plan well and have a good trip.
