Rules in force · 8Non-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.
  • United Kingdom ↗Most visitors who do not need a UK visa now need an Electronic Travel Authorisation (ETA) before travelling; this includes EU nationals. Irish citizens are exempt. Check the UK government site for your passport.
  • United Kingdom ↗The UK is outside the EU and the Schengen area; a Schengen visa is not valid for the UK.
  • United Kingdom ↗Driving is on the left; London has congestion and emissions charges for most vehicles, so do not drive in the city.

Glamorgan is the old county covering Cardiff, Swansea and the South Wales valleys between them. Cardiff is the capital with the castle, museum and stadium; Swansea is the gateway to the Gower beaches. The two are about an hour apart by train, so pick one base and day-trip the rest. The coast and the valleys reward a car; the cities do not need one.

  • Cardiff + Swansea + the valleys + the Gower in 2 days is mostly motorway and train time.
  • Valley rail and bus services thin out in the evening and on Sundays; check the last connection before you go.

May to September is the reliable window for coast and hills; school holidays fill Gower and Barry beaches.
