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.

Cardiff is Wales's capital and a compact, walkable city of about 360,000 people, built on coal money and rebuilt around a waterfront bay. The castle, the civic centre museums and the Victorian arcades sit within a 20-minute walk of each other, so two nights covers the core. Summer brings festivals and outdoor drinking; winter is mild but wet. It works as a stand-alone city break or a stop on a London–Swansea rail line.

Arrive & move

Airports are listed under At a glance; this is how to move once you are in

Getting around

The centre is flat and walkable: castle to the bay is about 25–30 min on foot along the Taff, or 5 min by train from Cardiff Queen Street to Cardiff Bay. Local trains are run by Transport for Wales and Great Western Railway (GWR); tap or buy at the station. Buses cover the suburbs but are slow in traffic. Driving is a liability in the centre — use park-and-ride from Caerphilly, Cogan or Radyr if you arrive by car.

See & do

Day-trips, door to door

Day-trips

Door-to-door, not ride time
Swanseago

Door to door: About 1 h 15 min

Train from Cardiff Central, about 1 h

Swansea's own bay and market make a full day; the Gower needs a car or bus and more time.

Bridgend

caution

Door to door: About 45 min to town; add 20 min for Porthcawl beaches

Train from Cardiff Central, about 25–30 min

Town centre has no beach. For the coast, take a local bus or taxi to Porthcawl (about 15–20 min).

Pontypridd

go

Door to door: About 45 min

Train from Cardiff Queen Street, about 30 min

Valleys town with a market and access to the Taff Trail; half a day is enough.

Barry

go

Door to door: About 40 min

Train from Cardiff Central, about 25 min

Barry Island seafront and beach; best on a dry day in summer.

Neath

caution

Door to door: About 1 h

Train from Cardiff Central, about 45–55 min

A stop toward Swansea and the Brecon Beacons edge; not a destination on its own for most trips.

Llantrisant

caution

Door to door: About 1 h

Train to Pontyclun then bus or taxi, or drive

Hilltop town with a royal mint; awkward by public transport.

Port Talbot

skip

Door to door: About 1 h

Train from Cardiff Central, about 40–50 min

Industrial town with few visitor draws; pass through toward Swansea instead.

Eat & sleep

Which area to sleep in

Where to sleep

Areas, not hotels: pick the one that fits your arrival time and plans.

City centre (Castle, Queen Street, St David's)

Best first base: castle, arcades, shops and both main stations on foot. Priciest and noisiest on match nights.

Cardiff Bay

Waterfront hotels, restaurants and the Millennium Centre; 15–20 min by train or bus from the centre, quiet at night.

Cathays and Roath

Student and café district near the university; cheaper beds, 15–25 min walk to the castle.

Pontcanna

Leafy residential streets with pubs and brunch spots; 20 min walk west of the castle, good for longer stays.

Watch out

Safety

Cardiff is a safe, friendly big city by UK standards; the real annoyances are rain, match-day crowds and late-night bar strips. Keep to lit streets, watch your bag in packed pubs, and use 999 only for emergencies.
  • Match days at Principality Stadium (rugby and football) fill hotels and pubs and close streets; book beds weeks ahead or avoid the date.
  • It rains often and without warning: a light waterproof beats an umbrella in the wind.
  • Cardiff Bay is a 25–30 min walk from the centre, not next door — plan the return leg or take the train.
  • Some city-centre bars and clubs get rowdy late on weekends; standard big-city night-out rules apply.
  • Sunday trading is shorter in Wales: many shops open about six hours only.

Coming as the guide grows

  1. Airport-to-bed contract for CWL and BRS: last bus and train times field-checked, taxi fallback, overnight rung.
  2. Four walking clusters with rescue anchors: castle and centre, civic centre and Cathays, the bay, Pontcanna and the Taff.
  3. Place pages with verified cutoffs (Cardiff Castle, National Museum, Millennium Centre, St Fagans) and eat pages with last orders.
  4. Match-day and rain-day fixtures so gates A–D can go green.
