Quick Answer
The best overall way to travel from Cardiff Airport (CWL) to Penarth is by taking the T9 Airport Express bus to Cardiff Central Station, followed by a short 10-minute train journey. This combination is reliable, frequent, and cost-effective, with a total travel time of 60-75 minutes and a cost of approximately £5-£9 per adult. For the fastest door-to-door service, a taxi takes 25-40 minutes but costs £35-£50.
The Public Transport Strategy: Airport → City → Penarth
Cardiff International Airport (CWL) is located in Rhoose, Vale of Glamorgan, approximately 12 miles (19 km) west of Cardiff city centre and 10 miles (16 km) from Penarth. Crucially, there is no railway station at the airport. Therefore, all public transport journeys to Penarth involve a two-stage process:
- Stage 1: Get from Cardiff Airport to Cardiff City Centre (specifically Cardiff Central Railway Station or bus interchange).
- Stage 2: Travel from Cardiff City Centre to Penarth via train or local bus.
The key decision point is your choice for Stage 1. The dedicated T9 Airport Express bus is the primary and most efficient link for this leg.

This is the most recommended route for balance of speed, cost, and ease.
Step 1: Airport to Cardiff Central (By T9 Bus)

- Journey Time: 35-45 minutes to Cardiff Central (Stand 8).
- Ticket: Buy on board from the driver. Contactless payment (card/phone) is accepted and often offers a daily price cap. A single adult fare is around £4-£5.
- Key Advantage: Drops you directly at the entrance to Cardiff Central Railway Station.
Step 2: Cardiff Central to Penarth (By Train)
From the T9 bus stop, enter Cardiff Central Station. Trains to Penarth are frequent services operated by Transport for Wales (TfW).
- Line: Typically the Vale of Glamorgan Line or services heading to Penarth/Bridgend.
- Frequency: Trains depart every 15-30 minutes throughout the day.

Alternative Train Route (Budget Option)
If the T9 bus is not running or you prefer a cheaper (but slower) Stage 1, you can use local buses (like the 304/X45) to Barry or Rhoose and then catch a train to Cardiff Central. This is more complex and only advised for experienced travelers or those on a very tight budget.
| Leg | Service | Frequency | Duration | Approx. Cost (Adult Single) |
|---|---|---|---|---|
| Airport → Cardiff Central | T9 Airport Express Bus | Every 20 mins | 35-45 min | £4.00 - £5.00 |
| Cardiff Central → Penarth | Transport for Wales Train | Every 15-30 mins | 10-12 min | £2.70 - £3.50 |
| TOTAL | Bus + Train | -- | 55-70 min | £6.70 - £8.50 |
Bus Guide: Direct & Local Bus Options
While the T9 + train combo is superior, a bus-only journey is possible and can be marginally cheaper, though significantly slower and less direct to central Penarth.
Option A: T9 Bus + Local Bus in Cardiff
Take the T9 to Cardiff Central. From the adjacent bus station (Sophia Gardens or Central Station Interchange), catch a local bus to Penarth (e.g., Service 93, 94, or 95). Total journey time can exceed 80-100 minutes. Useful if your final destination in Penarth is closer to a bus stop than the train station.
Option B: Local Bus (304/X45) + Train from Barry
A complex but cheap alternative for the budget-conscious:
- Take local bus 304 or X45 from the airport to Barry Docks Train Station or Barry Town Station.
- Alight the bus and catch a train from Barry to Penarth (often requiring a change at Cardiff Central or Grangetown).
Key Bus Information & Tips
- Timetables: Always verify bus times before travel, as services (especially local ones) can be reduced on evenings and Sundays.
- Luggage: The T9 bus has dedicated luggage space. Local buses may have limited space for large suitcases.
- Ticketing: Consider an "Iff Card" or contactless payment for seamless travel across multiple bus operators within the Cardiff region.

Essential Traveler Tips & Local Experience
Navigate like a local with these insights gathered from frequent travelers and residents.
Luggage Strategy
- Pack Light for Public Transport: Navigating bus steps, train aisles, and stations is easiest with wheeled suitcases and a backpack.
- Consider Luggage Forwarding: If you have excessive luggage, services like Send My Bag can ship it directly to your Penarth accommodation, allowing you to travel with just a day pack.
Navigation & Connectivity
- Use Digital Planners: The Traveline Cymru website/app is the authoritative source for real-time public transport schedules and journey planning across Wales.
- Cardiff Central Station: Allow a few minutes to navigate. The T9 bus stops near the main entrance; follow signs for platforms. Trains to Penarth typically depart from Platforms 5, 6, or 7.
- Free Airport WiFi: Use Cardiff Airport's free WiFi to check bus times or book a taxi upon landing.
Money-Saving Advice
- Contactless is King: Using the same contactless card/device for both bus and train travel can trigger automatic daily/weekly price caps, potentially saving money.
- Railcards: If you have a National Railcard (e.g., 16-25, Two Together, Senior), you can get 1/3 off the train portion (Cardiff Central to Penarth). The discount cannot be applied to the T9 bus fare.
- Group Travel: For 3-9 adults traveling together by train, ask about GroupSave discounts at the ticket office, offering off-peak travel for the price of 2.
Timing & Peak Considerations
- Weekday Rush Hour (7:30-9:00 AM, 4:30-6:30 PM): Traffic on the A4232 can delay the T9 bus and taxis. Train carriages can be busy with commuters.
- Event Days: When major events are on at the Principality Stadium in Cardiff, all transport into the city will be extremely busy. Plan extra time.
- Sunday & Bank Holiday Service: Public transport often runs on a reduced timetable. Always check schedules in advance for the day of your travel.
FAQs: Cardiff Airport to Penarth Common Questions
Is there a direct train from Cardiff Airport to Penarth?
No, there is no direct train service. You must take a shuttle bus or taxi from Cardiff Airport to Cardiff Central Railway Station first, and then catch a train to Penarth. The total journey involves two separate legs of public transport.
What is the cheapest way to get from Cardiff Airport to Penarth?
The cheapest way is by combining the T9 Airport Express bus to Cardiff Central and then a local train to Penarth. The total cost can be as low as £5-£7 per adult one-way, especially if you use contactless payment or purchase a Railcard-discounted ticket.
How long does the taxi take from Cardiff Airport to Penarth?
A direct taxi or private transfer takes approximately 25 to 40 minutes, depending on traffic conditions. It's the fastest door-to-door option, but also the most expensive, with fares ranging from £35 to £50.
Can I use a contactless bank card for public transport?
Yes, contactless payment (card or mobile device) is widely accepted. You can use it on the T9 Airport Express bus and for train travel between Cardiff Central and Penarth. It often provides the best daily fare capping. Remember to tap in and tap out on trains.
What should I do if my flight arrives very late at night?
If your flight arrives after the last T9 bus (around midnight) or train, your only reliable public option is a taxi. Pre-booking a private transfer is highly recommended for late-night arrivals to guarantee a ride and potentially secure a better fixed rate.
Is the T9 bus reliable for catching a train connection?
Generally, yes. The T9 Airport Express runs every 20 minutes for most of the day and is timed to connect with frequent train services at Cardiff Central. However, always allow a buffer of 30-45 minutes between your scheduled bus arrival and train departure to account for potential flight delays, baggage wait, or traffic.
Where exactly in Penarth do the trains and buses stop?
Trains stop at Penarth Railway Station, located centrally on Station Road. Local buses (like the 93 or 94) from Cardiff will stop at various points along Penarth's main roads, such as Windsor Road. The specific stop depends on your final destination; it's best to check using the Traveline Cymru planner.
Are there any discounts for families or groups travelling together?
Yes. On trains, look for Family & Friends Railcards or GroupSave discounts (for 3-9 adults travelling together). For taxis, groups of 3 or 4 can often find the cost per person comparable to public transport, making it a viable and convenient option. Always ask the taxi company or pre-booked service about group rates.
