Transport To, From and Within Cardiff
Cardiff is readily accessible by road, air and rail, so whatever direction you're heading from you will be able to get there with a minimum of stress. While you're in the city you also have extensive transport options, with some great public transportation to make best use of. If you're travelling outside of the city itself, you may feel the benefit of having a car with you, depending on what areas you're planning on exploring.
Road
Cardiff connects to London, Swansea and Newport via the M4 motorway, so if you're travelling by car you'll more than likely find yourself on it. The A470 is one of the roads you're likely to use when moving around the city area by car. If you are driving at the busy times of day, you should expect very heavy traffic as the city is a really busy one with commuters. The central parts of the city can also be very difficult to find parking places in, so if you are driving do bear this in mind.
Various bus and coach operators service Cardiff, including National Express, Stagecoach and First Cymru. Cardiff Central Bus Station is the main hub for bus services, and lies on Wood Road near the train station. Bus services connect the city to Swansea, Newport, South Wales and the Brecon Beacons.
Air
Cardiff Airport is located pretty close to the city, only 12 miles away in fact. This makes air travel to Cardiff particularly convenient, as you can easily make your way between the city and the airport by either bus or train, with both services prompt and efficient. The airport connects the city to locations across Britain, Europe and the globe, with many places enjoying access to direct flights.
Rail
Cardiff Central Railway Station is Wales' biggest, with lots of services connecting the city to spots around the country, as far away as Scotland, the north of England and of course London. Train services also operate around the city and surrounding areas, and the light rail Valley Lines network services lots of the suburban areas.
Bike
Cardiff is a popular place for cyclists, and there are some great routes you can use to explore the city while keeping active. The Taff Trail is one such route, also used by walkers. The trail basically follows the River Taff, and links into the National Cycle Network. You can also easily hire a bicycle in Cardiff, as such services are widely available on account of how flat and pleasant to cycle in the city is.
Local
Within the city, public transport is largely provided by bus services. Cardiff Bus operate these routes, and you can enjoy good value if you choose to purchase a travel pass for your trip, many varieties of which are available. Of course this depends on where you're staying and which parts of the city you want to explore, but Cardiff is a lovely city to walk around, so if you're not going too far this is well worth considering.
