What to see, where to stay and the best time to visit Dublin, Ireland.

Dublin is a compact, walkable capital on Ireland's east coast, with 592,713 people and a mix of old stone streets, museums and a famous pub culture. Visitors spend their days moving between Trinity College, cathedrals, Dublin Castle and riverside neighbourhoods, then talking to locals in the evening. June and August bring the warmest, driest weather of the year, making them the best months to visit if good weather matters to you.
Dublin's main sights—Trinity College, Kilmainham Gaol, Guinness Storehouse, the museums and cathedrals—can fill 2 to 3 full days, with time left over to explore a neighbourhood like Temple Bar or Portobello.
City centre
Ireland's oldest university displays the Book of Kells, a richly decorated medieval gospel manuscript, next to the Old Library's Long Room. The Long Room is undergoing a long conservation project, so check what is on show before you book. The campus itself is free to walk through.
Kilmainham
A former prison where many leaders of Irish rebellions were held and executed, seen only on a guided tour. It is one of the best places to understand modern Irish history. Tours often sell out, so book ahead.
The Liberties
A multi-floor visitor centre about Guinness beer at the St James's Gate brewery, ending in a rooftop bar with city views. It is Dublin's most visited paid sight and gets very crowded; skip it if you are not interested in beer or branding.
Kildare Street
Holds Ireland's finest prehistoric gold, Viking objects and preserved bog bodies. Entry is free, which makes it good value on a rainy day.
The Liberties
Ireland's largest cathedral, with a long link to the writer Jonathan Swift, who was dean here and is buried inside. The park beside it is a pleasant place to rest.
Old City
Dublin's medieval cathedral, known for its large crypt, one of the oldest structures in the city. It is a short walk from St Patrick's, so many visitors see both on the same morning.
Dame Street
For centuries the seat of British rule in Ireland, now used for state events. You can see the ornate State Apartments and, on guided tours, remains of the Viking-era defences below ground.
Dublin Castle grounds
A free museum of manuscripts, rare books and art from Asia, the Middle East and Europe, collected by one man. It is quieter than the big sights and easy to combine with Dublin Castle.
Docklands
An interactive museum about why millions of people left Ireland and what they did abroad. It suits families and anyone with Irish roots, though visitors who prefer real objects to screens may find it light.
West of city centre
One of the largest enclosed city parks in Europe, with a herd of wild deer, Dublin Zoo and the President's residence. Renting a bike is the easiest way to see it, as distances are long on foot.

The best areas to base yourself and who each one suits.
Good for nightlife, short stays, groups
A small area of narrow, cobbled streets beside the River Liffey, packed with pubs, live music and restaurants. You are central and can walk almost everywhere. It is loud late into the night, especially at weekends, so light sleepers should stay elsewhere.
Good for couples, food lovers, quieter nights
A residential area along the Grand Canal, south of the centre, with cafés, restaurants and good local pubs. It feels more like everyday Dublin but is still walkable to St Stephen's Green. Choice of places to stay is smaller than in the centre, so book early.
Good for repeat visitors, budget-minded, local feel
These north-side neighbourhoods have old red-brick streets, independent cafés and traditional pubs, plus the Luas tram line into the centre. They are close to the Jameson distillery and Phoenix Park. The area is further from the main southside sights, and some streets feel quiet or rough late at night.
Good for families, business travellers, quiet
A leafy, well-off area south-east of the centre with large Georgian and Victorian houses, embassies and the Aviva Stadium. It is calm and safe-feeling, with good bus and DART rail links. The downside is that evenings are quiet and you will need a longer walk or short ride to reach the main sights and nightlife.
Good for sea lovers, slower trips, families
A seaside town south of the city with a long pier, a coastal promenade and easy access to walks along Dublin Bay. The DART train takes you into the city centre. It is not ideal for a short first visit, because you spend time travelling in and out each day and late-night options back are limited.
