What first-timers get wrong in Dublin
Bus drivers take Leap cards and contactless but give no change for cash, so exact coins or nothing. Adult fares cap automatically at 5 euro a day and 29.20 a week, which means a separate travel pass is usually pointless. Kilmainham Gaol and the Book of Kells must be booked online in advance. Tip about ten percent in restaurants and nothing at all at the bar.
What's actually worth your time in Dublin
Trinity College's Book of Kells is genuinely extraordinary and genuinely two open pages, and the Long Room above it has had large numbers of volumes removed for conservation, so check the current state before paying. Kilmainham Gaol is timed, state-run and sells out well ahead. The Guinness Storehouse starts near 26 euro with a pint included. St Patrick's and Christ Church both charge admission.
Dublin's museums, and which one to pick
Dublin's best museums cost nothing. The National Museum of Ireland's Archaeology branch on Kildare Street holds the Iron Age bog bodies and the Ardagh Chalice; Decorative Arts sits at Collins Barracks and Natural History, the Dead Zoo, keeps its Victorian cabinets intact. The National Gallery, free as well, has Caravaggio's Taking of Christ, rediscovered in a Jesuit dining room in 1990. The Chester Beatty is also free.
Dublin with kids, realistically
Free national museums make wet days cheap, which matters in a city that drizzles constantly. Dublin Zoo sits inside Phoenix Park, the largest enclosed city park in Europe, where wild fallow deer graze in the open. Imaginosity in Sandyford is built for under-nines. The DART along the coast to Howth or Bray is an outing in itself, and the Luas is level-boarding for prams.
When the weather turns in Dublin
Dublin rain is persistent light drizzle rather than a downpour, so days rarely collapse outright; locals simply carry on. When it does settle in, the free National Gallery, National Museum branches and Chester Beatty keep you dry at no cost. EPIC at CHQ tells the emigration story indoors. Glasnevin Cemetery's guided tours run in any weather and are better in bad.
