As far as I am aware there are no Cretaceous deposits in Ireland, let alone the KT boundary.

If you're talking about Ireland as an island rather than as a state, then there are some Cretaceous chalky deposits along the north Antrim coast (known as the Ulster White Limestone Formation) - interesting features include caves with stalactites, eg. Larrybane cave. There is very little though, most of the sedimentary rock in Ireland is much older, which partially explains why there is little evidence of dinosaur fossils in the country.

Unfortunately if you want to see exposure of the dramatic K-T boundary you'll really have to head to North America - Colorado in the USA and Alberta in Canada seem to have the best examples of the iridium anomaly that characterise the boundary
