💰💶💳 Is it worth hiring a car in Cardiff?
These scores reflect the practical factors that affect whether renting a car is convenient, good value, and stress-free.
🚆 Airport access and onward rail options
Cardiff Airport is unusual among regional hubs because it has a through-station on the nearby main line. Trains do not terminate there but pass through on regular routes. Even so, you still need a short shuttle connection between the station and the terminal. It isn’t the closest airport transfer you’ll ever take, but it works, and it becomes especially helpful if you plan to continue by train across South Wales.
For example, you can arrive, hop the shuttle, and then ride trains toward Swansea, Bridgend, Newport, or into Cardiff Central. The same rail network links the capital with former mining valleys, and new tram-train improvements promise smoother journeys. These services make Cardiff a rare UK regional city where you can genuinely land, transfer, and carry on exploring without a car.
🚶♀️ Around the city without driving
The centre is compact, with Cardiff Castle, Bute Park, Principality Stadium, and the riverside all easy to walk. Cardiff Bay, the Senedd, and the waterfront restaurants are also reachable by train, bus, or a short taxi. If your itinerary covers museums, match days, and short hops to Penarth or Barry, public transport plus walking works well.
🚗 When a rental car is worth it
However, Cardiff is also the natural launch point for the wider coast. Roads reach surfing beaches, cliffs, and nature reserves that rail lines do not. The Gower Peninsula is the best example: its coves, farms, and viewpoints are magical, but buses are slow and infrequent. With a hire car, you can explore Oxwich, Three Cliffs Bay, Rhossili, or tiny villages on your own rhythm. Likewise, reaching one valley and then crossing sideways into another is far easier by road than by train, because rail routes mostly run lengthways.
Rental desks at Cardiff Airport are straightforward, and picking up there before heading into rural Wales is common. If you are arriving via Bristol or Heathrow instead, you can still reach Cardiff by train, explore the city, and only rent a car later. That split approach often saves money and parking stress.
🎯 Conclusion – should you rent a car in Cardiff?

🚶♀️ Skip the car if you mainly explore central Cardiff, Cardiff Bay, Valleys rail routes, or plan point-to-point trips across South Wales by train.
-
❔ Consider a car if you want flexibility to roam the Gower, hop between valleys, or search out quieter beaches and viewpoints where public transport thins.
