May is one of the better walking months for Phoenix Park, the Liberties, and Docklands paths.
City overview
Dublin sits on the River Liffey where Georgian squares, Viking-medieval lanes, literary pubs, Trinity College, the Liberties, Temple Bar, Smithfield, and St Stephen's Green make a compact city-center route. The city works best on foot, with DART coastal trains and Luas trams extending the map to Howth, Dun Laoghaire, and the docklands.
Food & drink
Dublin food is pub, market, and coast-fed: a full Irish breakfast plates sausage, bacon, eggs, pudding, beans, and tomato, Irish stew slow-cooks lamb or mutton with potatoes, seafood chowder uses Atlantic shellfish, and boxty turns potato into pancakes. The Brazen Head, Moore Street, George's Street Arcade, Temple Bar Food Market, Capel Street, and Howth seafood stops add soda bread, fish and chips, oysters, and Guinness pours.

City overview
Galway is Ireland's Atlantic city of Latin Quarter streets, trad-music pubs, university energy, harbor walks, festivals, and day trips into Connemara, the Aran Islands, and the Cliffs of Moher. Weather changes quickly in every month, so the best pages need rain-aware plans, festival timing, and realistic day-trip buffers.
Food & drink
Galway is strong on seafood, oysters, pub food, bakeries, modern Irish restaurants, and late-night casual eating around Quay Street and the West End. Autumn brings oyster demand, while summer festival periods make small central dining rooms fill quickly.
