Merthyr TydfilMerthyr Tudful
Give Merthyr one full day plus a night if you want Bike Park Wales or the Brecon Mountain Railway; otherwise day-trip it from Cardiff, 1 h by train.
Merthyr Tydfil is a former iron and coal town on the southern edge of Bannau Brycheiniog (the Brecon Beacons), 22 miles north of Cardiff up the A470. Its draw is industrial history plus outdoor access: Cyfarthfa Castle and its park, the Brecon Mountain Railway into the national park, and Bike Park Wales. The town centre is small and quiet; most visitors come for the hills, not the streets.

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.
