Ireland was centered on Dublin and had a great mix of city landmarks and coastal scenery. In the city, I moved through O'Connell Bridge, Trinity College Dublin, Dublin Castle, St. Patrick's Cathedral, Grafton Street, and the National Botanic Gardens, with airport and rail points naturally bookending each day. The core felt compact enough to explore deeply while still offering a lot of variety block to block.
The coastal segment around Dalkey and Killiney gave the trip a second personality. Time in the Dalkey Coastal Zone and Killiney Hill Park added open views and a slower pace that contrasted nicely with central Dublin. That city-and-coast balance made the overall visit feel complete rather than one-dimensional.
