Cardiff travel guide
Bute's castle, Victorian arcades, rugby days and the barrage at Cardiff Bay
Wales's capital packs a castle with Roman, Norman and Victorian layers, free national museums and the rebuilt waterfront of Cardiff Bay into a flat, walkable centre. The driest, mildest weather runs from May to September, and a rugby international changes the whole city. Two or three days is enough. Costs are very high, and most visa-free visitors need an ETA.
Wales keeps its capital on the flat land where the Taff, Ely and Rhymney rivers meet the Bristol Channel. Cardiff grew from a small town into one of the world's great coal ports in the 19th century, and that money paid for the Gothic fantasy rooms of Cardiff Castle, the white stone civic buildings of Cathays Park and a web of glass-roofed shopping arcades.
A big stadium sits a few minutes' walk from the castle gate. On Six Nations weekends the Principality Stadium's crowd spills into St Mary Street and the whole centre turns red, which is either the best or the worst time to visit depending on whether you have a ticket.
South of the centre, the old docks became Cardiff Bay after a barrage turned the tidal mudflats into a freshwater lake. The Senedd, the Wales Millennium Centre and the little white Norwegian Church stand along the waterfront, and a path runs across the barrage to Penarth.
Bilingual signs are everywhere, though English is spoken by everyone. The free National Museum holds Wales's art collection, while St Fagans on the western edge rebuilds centuries of Welsh life in the open air.
Two or three days covers the city comfortably, with Castell Coch and Caerphilly Castle as easy add-ons.

Getting there
Rhoose airport links and GWR from Paddington
Cardiff Airport (CWL) lies west of Barry in the Vale of Glamorgan, with flights mostly to UK and European cities. The 304 bus runs from the terminal into Cardiff by way of Barry; alternatively the 905 shuttle bus links the terminal with Rhoose Cardiff International Airport station, where Transport for Wales trains continue to Cardiff Central and Queen Street. Many visitors fly into Bristol instead, then take the National Express 216 coach direct to the city centre or the airport bus to Bristol Temple Meads for a GWR train. From Heathrow, coaches run straight to Cardiff, or take the Elizabeth line into Paddington. Great Western Railway runs roughly half-hourly from London Paddington via Reading, Swindon, Bristol Parkway and Newport. Cardiff Central handles intercity trains; Queen Street serves the valley lines and the Bay shuttle.
- Bus 304
- Cardiff Airport into Cardiff by way of Barry
- Bus 905 plus train
- Airport to Rhoose station, then Transport for Wales trains to Central
- GWR from London
- Paddington to Cardiff Central, about every 30 minutes
- National Express 216
- Bristol Airport direct to Cardiff city centre
- On match days trains from London and Bristol run full and the station uses queuing pens after the final whistle; travel early or stay overnight.
Where to stay
Castle quarter, Bay, Pontcanna
The compact centre puts the castle, the arcades and the stadium within a few minutes of each other. The Bay is quieter and more spread out, and the leafy western districts suit longer stays.
- City centre
- Walk to everything, but St Mary Street and Greyfriars Road are loud late on weekends
- Cardiff Bay
- Waterfront hotels near the Millennium Centre; about a mile from the castle
- Pontcanna and Canton
- Victorian terraces near Bute Park, cafés on Cowbridge Road East and Chapter Arts Centre
- Cathays and Roath
- Student streets and guesthouses near the civic centre and Roath Park
Getting around
Aquabus on the Taff and Cardiff Bus routes
The city is flat, and the walk from the central library to the Bay is roughly a mile on level pavements. Cardiff Bus runs the main network and accepts contactless payment on boarding; its circular routes 1 and 2 link the centre with the Bay and inner districts. Queen Street station runs a frequent shuttle train to Cardiff Bay station. For a slower ride, the Aquabus boat sails between the Castle Grounds and Mermaid Quay, though sailings depend on river levels and weather. Cyclists have signposted routes, including the Taff Trail through Bute Park, and PedalPower rents bikes in Pontcanna and the Bay. Llandaff Cathedral is about two miles from the castle, an easy bus or bike ride.
- Cardiff Bus
- Tap on with a contactless card; routes 1 and 2 circle the centre and Bay
- Bay shuttle train
- Queen Street to Cardiff Bay, several trains an hour
- Aquabus
- Castle Grounds to Mermaid Quay along the Taff
- Remove all valuables from parked cars; car crime is the city's main safety issue.
Know before you go
What makes Cardiff worth the trip, and what catches visitors out.
Why travelers love it
- The Bute rooms in Cardiff Castle, where barely a surface escapes carving, gilding or painted mural.
- National Museum Cardiff, free to enter and strong on 19th-century French painting.
- Walking the barrage from Mermaid Quay towards Penarth with the Bristol Channel on one side and the lake on the other.
- St Fagans, an open-air museum of rebuilt Welsh farmhouses, chapels and workers' cottages.
Good to know
- Match days change everything: roads around the stadium close and pubs fill hours before kick-off.
- Restaurant tables in the centre and at Mermaid Quay are hard to get on Friday and Saturday nights without booking.
- Rain is likely in any month, and the autumn months are the wettest; pack a waterproof.

Castle keep to Mermaid Quay in two unhurried days
Two days cover Cardiff. Day one takes in Cardiff Castle and its Bute apartments, Bute Park, City Hall and National Museum Cardiff, then the Victorian arcades and Cardiff Market. Day two rides the Aquabus to Mermaid Quay for the Senedd, the Wales Millennium Centre and the Norwegian Church, with Penarth or St Fagans in the afternoon.
Day one, morning. Start at Cardiff Castle when it opens: climb the Norman keep, see the Roman wall and book a guided tour of the Bute apartments. Walk north through Bute Park along the Taff.
Afternoon. Cut across to Cathays Park for City Hall and National Museum Cardiff, where the Impressionist rooms alone justify an hour or two. Return to the centre through the Victorian arcades, Castle Arcade, Morgan Arcade and Royal Arcade, and the indoor Cardiff Market.
Evening. Dinner in the centre or in Pontcanna, then a pint of locally brewed Brains if a match is on.
Day two, morning. Ride the Aquabus downriver to Mermaid Quay. Look in at the Senedd, the Wales Millennium Centre and the Norwegian Church, where Roald Dahl was baptised.
Afternoon. Walk across the barrage to Penarth for its Victorian pier, or take the bus out to St Fagans for its open-air village. End with a show at the Millennium Centre or a waterfront meal back in the Bay.
Travelling on to England's cities? The train reaches Bath in about an hour and London in around two.
Welsh cakes, cawl and the Victorian market hall
Start eating in Cardiff at Cardiff Market, the glass-roofed Victorian hall between St Mary Street and Trinity Street, for warm Welsh cakes, cockles and laverbread. Cawl, a lamb and leek broth, appears on pub menus in the colder months. City Road in Roath, Canton and Pontcanna hold the most varied independent restaurants.
Cardiff Market, a glass-roofed Victorian hall between St Mary Street and Trinity Street, is the place to start. Stalls sell Welsh cakes, flat currant griddle cakes dusted with sugar and eaten warm, plus cockles and laverbread, a dark purée of seaweed traditionally fried with bacon for breakfast.
Cawl, a slow broth of lamb, leeks and root vegetables, turns up on pub menus in the colder months, often with Caerphilly cheese and bread on the side. Welsh rarebit, cheese sauce grilled on toast, is the classic café lunch.
For variety, follow the neighbourhoods. City Road in Roath is lined with Middle Eastern, Indian and Asian restaurants. Canton and Pontcanna have independent cafés and small dining rooms along Cowbridge Road East and Kings Road. The arcades hide old coffee shops and delis. Mermaid Quay in the Bay is mostly chain restaurants, so look a street back for anything more personal.
To drink, Brains is the Cardiff name you will see on the pumps of older pubs, with a fast-growing craft beer scene around the centre.
Winter Wonderland lights, Six Nations crowds and valley castles
Cardiff is liveliest in winter: Winter Wonderland runs beside City Hall from November into early January, and Six Nations home games fill the city in February and March. Summer is calmer, with highs of 17C to 22C and the least rain. Castell Coch, Caerphilly Castle and Barry Island make easy short trips.
Winter is lively here. Cardiff's Winter Wonderland sets up an ice rink, rides and festive stalls in the civic centre beside City Hall from November into early January. The Six Nations rugby championship follows in February and March, when home games at the Principality Stadium make the centre one big crowd.
The weather explains why summer is calmer and more comfortable. Highs climb from 17C in May to 22C in July, lows sit at 9 to 13C, and rainfall is at its lowest, around 72 to 84 mm a month. October to December is the wettest stretch, at 129 to 140 mm, with highs of 9 to 15C.
Short trips are simple. Castell Coch, a Victorian fairy-tale castle built for the same Marquess of Bute, sits in beech woods just north of the city. Caerphilly Castle, one of the largest in Britain, is a short train ride up the valley line from Queen Street. Barry Island has a sandy beach and funfair, and in summer paddle steamers leave Penarth pier for cruises along the Bristol Channel. The Brecon Beacons are around 40 minutes' drive north.
Roman walls, Burges interiors and St Fagans
Cardiff's biggest sights are its castle, its rugby stadium and the open-air museum at St Fagans. The castle stands on a Roman fort of the mid-3rd century, the Principality Stadium opened beside the Taff in 1999, and St Fagans has gathered more than forty historic buildings from across Wales since 1948.
Inside the castle walls, the Normans raised a wooden keep on a mound about 40 feet high in the late 11th century. From 1868 William Burges remodelled the apartments for the 3rd Marquess of Bute in a lavish Gothic revival style, and the Bute family gave the castle and park to the city in 1947. Tunnels in the walls sheltered up to 1,800 people during Second World War air raids.
The Principality Stadium on Westgate Street holds 73,931 and has a fully retractable roof, so matches and concerts go ahead in any weather. Its city-centre site is why match days take over the streets around it.
St Fagans opened in July 1948 as the Welsh Folk Museum. Its 100-acre site holds farmhouses, chapels and workshops moved from all over Wales and rebuilt, so allow at least half a day.
