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.

Gwynedd is the northwest quarter of Wales: Snowdon and the slate valleys in the north, the Llŷn Peninsula reaching west, and the Cambrian coast running south to Barmouth and Tywyn. It is a county of small towns 20–60 minutes apart, so one base plus day trips beats moving hotels. A car is the flexible option; the Cambrian and North Wales coast lines cover the edges but not the middle.

  • Snowdon in trainers and a T-shirt is a mountain rescue call; check the forecast and take layers.
  • Rural buses run a few times a day and stop early; without a car, plan around the rail lines.
  • Many castles and small museums close or cut hours from November to March.

Coast and Llŷn
Mild and wet year-round; sea breezes keep summer cooler than inland.

Rainfall is high; summits can be in cloud while the coast is sunny. Snow on the tops roughly November to April.

May to September is the walking season and also the crowd peak; late May and September give the best mix of weather and space.
