Quick Answer
The fastest and most convenient way to get from Cardiff Airport (CWL) to Cardiff City Centre is by T9/T10 express bus, taking about 35-45 minutes and costing around £6-£8 one-way. For the cheapest option, take the local 304 bus to Rhoose Cardiff International Airport Railway Station, then a train to Cardiff Central, with a total cost from £4.50 but a longer journey time of 55-70 minutes. Taxis cost £35-£45 and take 30-40 minutes.
By Bus: The Direct & Best Value Option
The airport express bus service, operated by Cardiff Bus (T9/T10), is the most popular choice for its balance of speed, price, and convenience. It provides a direct link between the airport terminal and Cardiff's central bus station, Cardiff Coach Station (Sophia Gardens), and key city center stops like Cardiff Central Railway Station.
Key Details & Comparison
| Service | Route | Journey Time | Approx. Fare (One-Way) | Frequency | Key Features |
|---|---|---|---|---|---|
| T9/T10 Express (Recommended) | Airport → Cardiff City Centre (Stops at Central Station, Sophia Gardens) | 35-45 mins | £6-£8 (Pay on board or via app) | Every 20-30 mins (from early morning until late evening) | Direct, dedicated luggage space, comfortable coaches, free Wi-Fi on some services. |
| 304 Local Bus (Budget) | Airport → Barry → Cardiff City Centre (various stops) | 60-80 mins | From £2.50 (with IFF card) | Hourly | Cheapest public option, but slower and less direct. Connects to Rhoose train station. |
Where to Catch the Bus & Buying Tickets
The bus stop is located directly outside the main terminal arrivals hall—just follow the clear signage. You can:
- Pay the driver with cash or contactless card (exact change not always required but appreciated).
- Use the Cardiff Bus app to purchase and activate mobile tickets.
- Consider a day ticket if you plan to use buses in Cardiff later (£4.50-£5).
Insider Tip: During peak times or when large flights arrive, buses can fill up. Be prepared to queue, especially if you have large luggage. Check the official T9/T10 timetable for the most current schedule, as frequency reduces in the evenings and on Sundays.
By Train: The Scenic & Flexible Route
While there is no train station at Cardiff Airport itself, a combined bus-and-train journey offers flexibility and can be cost-effective, especially with a railcard.
Step-by-Step Guide:
- Take the Local 304 Bus or a Taxi to Rhoose Station: From the airport, board the 304 bus (15-min ride, ~£2) or a short taxi (5-min ride, ~£8-£10) to Rhoose Cardiff International Airport Railway Station.
- Catch the Train to Cardiff Central: From Rhoose, take a Transport for Wales train towards Cardiff Central, Bridgend, or Pontypridd. The train journey is 15-20 minutes.
- Arrive at Cardiff Central: This is the main hub, with excellent connections to local buses, taxis, and onward national rail services.
Train Information & Costs
| Leg of Journey | Operator | Typical Cost | Total Journey Time (Airport to Central) | Notes |
|---|---|---|---|---|
| 304 Bus (Airport → Rhoose Station) | Cardiff Bus | ~£2 (with IFF card) | 55-75 minutes (incl. wait/transfer time) | Bus times may not align perfectly with trains. Check schedules. |
| Train (Rhoose → Cardiff Central) | Transport for Wales | ~£3.50 (Off-Peak Day Single) | Trains run every 1-2 hours. Anytime fares are more expensive. |
Is it Worth It? For pure speed and convenience, the direct T9 bus wins. However, the train option is valuable if you have a Railcard (saving 1/3), are traveling to a destination beyond Cardiff Central, or arrive during a bus service gap. Always check real-time train times on National Rail.
By Taxi & Private Transfer: Door-to-Down Convenience
Taxis and pre-booked private transfers offer the ultimate convenience, taking you directly from the airport arrivals hall to your exact destination in the city center.
Costs & Options
- Official Airport Taxi Rank: Located outside the terminal. A metered fare to the city center typically costs £35 - £45 and takes 30-40 minutes, depending on traffic and your final destination.
- Pre-Booked Private Transfer: Companies like Dragon Taxis or Cardiff Airport Taxis offer fixed-price quotes. Booking online in advance can sometimes secure a slightly better rate (£30-£40) and guarantees a vehicle.
When is a Taxi the Best Choice?
Consider this option if:
- You are traveling in a group of 3-4 people, making the cost per person comparable to the bus.
- You have a lot of luggage or heavy/oversized items.
- You arrive very late at night or very early in the morning when public transport is limited.
- You have reduced mobility or are with young children requiring car seats.
Warning: Always use the official rank or a reputable pre-booked company. Avoid unsolicited offers inside the terminal.

Arrival & Timing

Final Destination in Cardiff
If your hotel or destination is near Cardiff Central Station or the Millennium Stadium/Sophia Gardens area, the T9/T10 bus is perfect. If you're staying further out (e.g., Cardiff Bay, Canton), a taxi from the city center or checking a local bus route from Central may be necessary.
Frequently Asked Questions (FAQs)
Is there a direct train from Cardiff Airport to the city center?
No, there is not. Cardiff Airport does not have its own railway station. The nearest station is Rhoose Cardiff International Airport Station, which requires a short bus (304 service) or taxi ride from the terminal.
What is the cheapest way to get from Cardiff Airport to Cardiff?
The 304 local bus is the absolute cheapest public transport option, with fares from £2.50. For a better balance of cost and speed, the combined 304 bus + train from Rhoose Station is a good budget alternative, costing from around £4.50 one-way.
How much is a taxi from Cardiff Airport to the city?
A taxi from the official rank costs approximately £35 to £45 for the 30-40 minute journey to Cardiff City Centre. Pre-booking a private transfer may offer a fixed price within a similar range.
How often does the T9/T10 airport bus run?
The T9/T10 express bus runs approximately every 20 to 30 minutes during the day, from early morning until late evening. Services are less frequent in the early morning, late evening, and on Sundays. Always check the current timetable before travel.
What should I do if I arrive at Cardiff Airport very late at night?
If you arrive after the last T9/T10 bus has departed (around midnight), your only public options are a taxi from the official rank or a pre-booked private transfer. It is highly advised to pre-book a transfer if you have a late-night arrival to ensure availability.
Is the T9 bus suitable for travelers with a lot of luggage?
Yes. The T9/T10 coaches are equipped with large, easily accessible luggage compartments underneath the bus. There is no formal limit, but space is shared with other passengers. For excessive amounts of luggage, a taxi or private transfer might be more comfortable.
Can I use my contactless bank card on the airport bus?
Yes. You can pay the driver directly using a contactless debit or credit card, as well as Apple Pay or Google Pay. Cash is also accepted.
Which option is best for a family with young children?
This depends on luggage and time. The T9/T10 bus is straightforward and avoids transfers. However, managing prams and children on a bus can be tricky. For ultimate ease, especially with car seat requirements, a pre-booked private transfer or taxi (where you can request seats) is often the least stressful choice, though more expensive.
