A practical breakdown of the neighbourhoods worth booking in Ireland's three most-visited cities, with distances, drive times and the areas I would skip.
Dublin: Trinity, Temple Bar and the Georgian south side
For a first visit, base yourself between Trinity College and St Stephen's Green. From here Grafton Street, the National Museum and the Dart at Pearse Station are all within ten minutes on foot, and Dublin Airport is roughly 25 to 40 minutes by car or the Aircoach. Hotels around Merrion Square and Fitzwilliam Square tend to be quieter and better value than the immediate Grafton Street frontage, and the Georgian terraces give you a sense of the city that a docklands chain hotel cannot.
Temple Bar is worth a walk through, not a night's sleep. The pubs are lively but the area is loud until the early hours and rooms above the strip carry a premium for the location rather than the comfort. If you want nightlife on your doorstep, look at Wexford Street and Camden Street instead, where locals actually drink. Smithfield, ten minutes north of the Liffey, has the Jameson distillery and good coffee, but check the exact address before booking.
Dublin: the coast, and when to skip the centre entirely
The coastal villages are a real alternative. Dún Laoghaire, Sandymount and Howth all sit on the Dart line, so you can be in the city centre in 20 to 30 minutes without paying centre prices. Howth is the strongest choice if you like walking, with the cliff path and the harbour seafood within a few minutes of the station; Malahide suits families because of the castle grounds and the wide beach. Bray, over the county line, is cheaper again and still connected.
What I would skip: hotels clustered around the airport unless you have an early flight. You save nothing on transfers if you still want three days in the city, and the surroundings are car parks and roundabouts. Also skip anywhere advertised as 'City Centre' that turns out to be beyond the North Circular Road; the walk into town is longer than it looks on a map. Late May to early September gives the best weather and the longest evenings, though it is also peak season, so book well ahead.
Cork: the city centre and the harbour towns
Cork is compact and best understood in two halves. The flat island between the north and south channels of the River Lee holds the English Market, Patrick Street and most of the hotels; it is the obvious base for a short stay and everything is walkable. Washington Street and MacCurtain Street add restaurants and bars without the noise of the main shopping streets. Cork Airport is about 15 to 20 minutes south by car, or a 20-minute bus to the city centre.
For a longer stay or a quieter trip, look at Kinsale, 25 to 30 minutes south of the city, or Cobh, 25 minutes by train from Kent Station. Kinsale has the restaurants, the harbour and the forts; Cobh has the heritage centre and the cathedral above the town. Both are more restful than the city and suit a two- or three-night stay. I would book the city centre for a first visit, then Kinsale if you have a car and a spare day. Best months are May, June and September.
Galway: Latin Quarter, Salthill and Connemara as a base
Galway is the smallest of the three and the easiest to navigate on foot. The Latin Quarter, around Quay Street and Kirwan's Lane, is the postcard version: buskers, pubs and the Spanish Arch, with hotels to match. Shop Street and Eyre Square are five minutes away and hold the larger properties. If you want quiet, look at the Claddagh and the Long Walk, where you get the Corrib views without the crowds, still ten minutes from the centre.
Salthill, two kilometres west along the coast, has the promenade and the beaches, and the walk into town takes about 25 minutes. It suits families and anyone who wants sea air over street noise. Galway is also the natural base for Connemara and the Burren: Clifden is about an hour and 15 minutes west, the Cliffs of Moher roughly an hour and a half south. I would book two nights in the Latin Quarter for atmosphere and a third in Salthill or Connemara for the landscape.
Choosing between the three
Dublin rewards three or four nights, Cork two, Galway two, with a car for the west. Rail links are good: Dublin to Galway is about two and a half hours, Dublin to Cork about two and a half by train from Heuston. If you are booking a single city, Dublin has the most beds and the widest range; Galway has the best atmosphere per euro in the west; Cork is the most affordable of the three for a mid-range room. Book the west first if you are travelling in July or August.
Frequently asked questions
Which area of Dublin is best for a first visit?
Stay between Trinity College and St Stephen's Green, or just south around Merrion Square. Grafton Street, the museums and Pearse Station are all within ten minutes on foot, and the airport is 25 to 40 minutes away.
Is it worth staying in Salthill instead of central Galway?
Yes if you want sea air, the promenade and quieter evenings. Salthill is about two kilometres west of the centre, a 25-minute walk, with regular buses. Central Galway suits a short stay better because everything is on your doorstep.
Do I need a car for Cork and Galway?
Not for the cities themselves, which are compact and walkable. A car helps for Kinsale, west Cork, Connemara and the Burren. Trains link Dublin, Cork and Galway, but the coastal and mountain detours need wheels.
