Driving from London to Cardiff

Driving Directions from London to Cardiff

Cardiff is due west of London, in south Wales. Take the M4 motorway out of west London, and you stay on this almost all the way to Cardiff. You cross the Severn Bridge, which is a toll bridge, though the toll is only payable when driving from England into Wales. It’s said in both anger and jest that you pay a toll to enter Wales, but the toll is collected on the English side of the bridge.

From London to Cardiff by Train

Trains from London to Cardiff leave from London’s Paddington Station. There are direct trains about every half-hour during the day, with a journey time of just over 2 hours. Trains from London arrive at Cardiff Central Station, which is right in the city centre. You can often find the best train ticket prices on the Raileasy website.

From London to Cardiff by Bus

The cheapest way to get to Cardiff from London is by bus, and in our view the bus to Cardiff is a better choice than the train. It only takes an hour or so longer, and the bus fares are much cheaper than the train fare. The cheapest fares of all are usually on the Megabus. Several buses leave London’s Victoria Coach Station every day, going direct to Cardiff, with a journey time of 3-4 hours, depending on the service. Do check that you get one of the faster services if possible.




The Megabus arrives in Cardiff at Kingsway Ffordd y Brenin, close to the city centre. Megabus fares are usually slightly cheaper than National Express, especially if booked in advance on the Megabus website. At some times of day and depending when you’re booking, National Express can work out cheaper so always compare the two websites.

National Express has several direct bus services a day from London’s Victoria Coach Station to Cardiff, as frequent as one an hour during weekdays, with a journey time of between 3 hrs and 3 hrs 25 mins. National Express buses arrive in Cardiff at the bus station on Wood Street, which is close to the Principality Stadium in the city centre. You are strongly advised to book tickets in advance. Check times and fares on the National Express website.
