Getting Around

South Wales is compact. You can cross the whole region in under two hours, which means you can base yourself in one place and reach most of it on a day trip. How you travel depends almost entirely on where you are going: the cities and the valleys are well served by rail, while the Gower, the Heritage Coast and most of the National Park really want a car.

Below you will find an honest answer on whether you need one, the train network and the best value tickets, the bus operators worth knowing, driving and parking, and the main walking and cycling routes.

It depends entirely on where you are going, and it is worth being straight about this rather than pretending otherwise.

You do not need a car if you are staying in and travelling between Cardiff, Newport and Swansea, or exploring the valleys. The South Wales Main Line runs frequently between the three cities, the Core Valley Lines reach up into the valleys from Cardiff, and city bus networks are good. Barry Island, Penarth, Bridgend and Porthcawl are all reachable by train, and Tenby and Saundersfoot are both on the rail network too.

You probably do need a car for the Gower Peninsula, the Glamorgan Heritage Coast and most of Brecon Beacons National Park. Bus services reach parts of all three, but they are infrequent, particularly outside the summer season and on Sundays, and the beaches and walking spots you most want to reach are often the furthest from a stop. If the Gower or the mountains are the point of your trip, hire a car.

A middle option that works well for a lot of visitors: base yourself somewhere on the rail network, use trains for the cities and the coastal towns, and hire a car for one or two days to do the Gower and the National Park properly. It is cheaper than a car for the whole trip and saves you parking in Cardiff.

The South Wales Metro

The rail network across South East Wales has been through the largest upgrade in its history. In March 2026, Transport for Wales announced that electrification of the Core Valley Lines was 100% complete, finishing a project worth around £1 billion that installed more than 280 miles of overhead wiring across the network.

All seven Core Valley Lines are now electrified: Treherbert, Aberdare, Merthyr, Coryton, City, Rhymney and Cardiff Bay. New Class 398 tram-trains run on the Treherbert, Aberdare, Merthyr and Cardiff Bay lines, with Class 756 tri-mode trains on the Rhymney, Coryton, Penarth, Barry Island and Vale of Glamorgan routes.

For visitors, the practical effect is that getting from Cardiff up into the valleys, out to Barry Island or across to Cardiff Bay is quicker, quieter and more reliable than it was. Transport for Wales has reported the Core Valley Lines as one of the most punctual networks in Britain in recent months. Further signalling upgrades and the completion of the new fleet rollout are expected to bring faster journeys and higher frequencies still.

Train tickets and travel passes

If you are spending several days exploring by train, a pass will usually work out cheaper than buying individual tickets.

The Explore South Wales Pass gives you four days of rail travel within an eight-day period, plus bus travel on all eight days. It covers a broad area including all the Cardiff Valleys services, the Vale of Glamorgan and Maesteg lines, Ebbw Vale, Newport to Gloucester, and west to Pembroke Dock, Milford Haven and Fishguard Harbour. At the time of writing it costs £129 for an adult and £64.50 for a child, with further discounts available with a Railcard. Bus travel is valid with major operators including Cardiff Bus, First Cymru, Stagecoach South Wales and selected TrawsCymru services.

For anyone travelling more widely, the Explore Wales Pass covers the whole country on the same four-days-in-eight basis.

If you are only making one or two journeys, buying advance singles online is usually cheaper than turning up and buying at the station, and a Railcard pays for itself quickly if you qualify for one.

Driving in South Wales is straightforward. The M4 runs the length of the region from the Severn crossings past Newport and Cardiff to Swansea and on toward Carmarthen, and the A465 Heads of the Valleys road runs east to west along the northern edge. Away from the motorway the roads narrow quickly, particularly on the Gower and in the National Park, where you should expect single track sections with passing places.

South Wales has some outstanding traffic-free routes. The Taff Trail runs from Cardiff Bay north to Brecon, following the river and old railway lines through the valleys. It runs around 55 miles, mostly traffic-free, and is one of the best long-distance cycle routes in Britain. The Celtic Trail crosses the south of the country from the English border west to Fishguard.

On foot, the Wales Coast Path runs the entire length of the Welsh coastline, and the South Wales sections take in the Glamorgan Heritage Coast, the Gower and the Pembrokeshire coast around Tenby. You can walk between beaches, and in most places you can start and finish at a village with a bus stop or a station.

Bike hire is available in Cardiff, Swansea and several of the larger towns, and bikes can be carried on Transport for Wales trains, though space is limited and reservations are advisable on busier services.
