Rules in force · 10Non-EU visitors get 90 days in any rolling 180-day window…

Europe ↗Non-EU visitors get 90 days in any rolling 180-day window, counted across all 29 Schengen states together — not per country; the Entry/Exit System now logs each crossing, so an overstay is detected automatically.
Europe ↗On the first Schengen entry since EES began, non-EU travellers give four fingerprints and a face photo at the border instead of a passport stamp; there is nothing to apply for or pay in advance.
Britain and Ireland ↗Neither the UK nor Ireland is part of Schengen: days spent here do not count towards the 90/180-day Schengen limit, and a Schengen visa does not admit you to either country.
Britain and Ireland ↗The island of Ireland runs on two currencies: euro in the Republic, pound sterling in Northern Ireland and Great Britain. Carry a card that pays in both without fees.
Britain and Ireland ↗Both islands drive on the left. Speed limits are in miles per hour in the UK (including Northern Ireland) and in kilometres per hour in the Republic of Ireland.
Ireland ↗Ireland is in the EU but not in the Schengen area; it sets its own entry rules and a Schengen visa is not valid for Ireland. Check Irish immigration for your passport.
Ireland ↗Ireland and the UK form the Common Travel Area, with no routine checks on the land border. Visitors who are not Irish or British must still meet UK rules (including the UK ETA where it applies) to enter Northern Ireland.
Ireland ↗Driving is on the left; rural roads are narrow with hedges and few passing places.
West Ireland ↗Drive on the left; minor roads are narrow and slow — plan 50 km/h average, not 80.
West Ireland ↗Fill up in towns; outside Galway city, fuel and charging points are sparse.

Mayo is Ireland's emptiest coastal county: bog, sea cliffs and island drumlins with few towns in between. Westport is the only base that works without a car — rail, Greenway and Croagh Patrick all start there. Castlebar is the practical town (rail junction, museum, cheap eats); Ballina suits the north and the Céide Fields. Everything west of Newport needs a car, and the weather decides your day, not your plan.
