Overview
Cardiff — Caerdydd — is Wales's compact capital: castle, national stadium and a revamped bay all within a 20-minute walk. For most UK travellers it's a rail or road trip, but direct flights link Cardiff with Scotland and Northern Ireland, and Cardiff Airport (CWL) clears quickly compared with the bigger hubs. Check the price charts on this page before you book.
Best time to fly to Cardiff
Cardiff's climate is mild and damp. July and August are the warmest and busiest months; late spring and September bring decent weather, thinner crowds and lower fares. Winters are cool and wet rather than icy, but Six Nations rugby weekends (February–March) and the Christmas markets push demand and prices up. The When to book chart above shows how fares move across the year for your dates.
Airlines and routes
Direct UK air links to Cardiff are limited, because rail and motorway cover most of the country well — London Paddington to Cardiff Central is roughly two hours by train, and there are no scheduled flights from London or Manchester. The flights that do run mainly connect Cardiff with Scotland and Northern Ireland: routes such as Edinburgh and Belfast City have been operated by Eastern Airways, with flying times of about one hour to one hour fifteen. KLM's Amsterdam service is useful if you're connecting to Cardiff from overseas. Check the routes listed on this page for current carriers.
Things to do in Cardiff
Most highlights are central or a short bus ride away:
- Cardiff Castle: Roman walls, a Norman keep and lavish Victorian interiors by William Burges, right in the city centre.
- Principality Stadium: home of Welsh rugby, with a retractable roof and behind-the-scenes tours on non-event days.
- St Fagans National Museum of History: a free open-air museum of re-erected historic Welsh buildings on the city's western edge.
- Cardiff Bay: waterfront dining around Mermaid Quay beside the Wales Millennium Centre and the Senedd.
- National Museum Cardiff: free galleries covering natural history and a strong Impressionist art collection.
At Cardiff Airport (CWL)
The airport sits at Rhoose in the Vale of Glamorgan, about 12 miles (19 km) south-west of the city centre. The 24-hour T9 Cardiff Airport Express bus runs to the city centre and Cardiff Central station in around 40 minutes. Rhoose Cardiff International Airport railway station, a short shuttle from the terminal, is on the Vale of Glamorgan line with trains to Cardiff Central in about 30 minutes. Taxis take roughly 30 minutes and car hire desks are in the terminal.
Top tips for finding cheap flights to Cardiff
- For domestic and short-haul routes, booking about four to eight weeks ahead usually lands the best fare — cross-check the When to book chart above.
- Avoid Six Nations weekends, major stadium concerts and school holidays, when flights and hotels climb together.
- Fly midweek: Tuesday and Wednesday departures are typically cheaper and quieter than Friday or Sunday.
- Compare airlines and nearby Bristol Airport, and weigh any fare against a direct train if you're travelling from England.
Travel essentials
