Ireland is full of American style courses, and these are the ones that everyone is aware of. However, there's also lots of older traditional style courses - Headfort old, the Hermitage, the Grange, Little Island, Mulingar, Tramore, the Curragh... I don't know how they compare to similar courses in Scotland, but they are needlessly written off by people visiting Ireland and by people who are discussing Irish golf.
If you don't want to go to an American style course when you're in Ireland, visit the links or else visit these courses.
