Paris Airport to City: CDG Express vs. RER B vs. Bus

You've just landed at Charles de Gaulle Airport. It's 11pm or 6am or somewhere in between, you're groggy, and you need to get to your hotel without losing your mind or your budget. Here's the honest breakdown of your three main options.

The CDG Express: Speed Wins, Wallet Loses

The CDG Express is the shiny new option, opened in 2024. It's fast—genuinely fast. You're in Paris proper in 32 minutes from the terminal, and you bypass all the metro shuffle nonsense.

The real story: It costs €17.45 one-way for an adult. It's automated, frequent (every 4-8 minutes during the day), and the trains are clean and modern. You get a reserved seat. If you're landing alone, exhausted, and willing to pay for convenience, this is the play.

But here's the thing: €17.45 becomes €34.90 round-trip. Factor in a hotel metro card or future travel, and you could've saved a tenner going another route.

The CDG Express terminates at Gare de l'Est (in the 10th arrondissement). If your hotel is on the Left Bank or near the Eiffel Tower, you're then hopping on the metro anyway. It's faster overall, but not by hours.

RER B: The Budget Backpacker Special

RER B is the workhorse. It's been here forever, it's reliable, and it costs €11.45 for a single ticket.

Realistic timing: 35-40 minutes door-to-door, assuming you don't get lost and the train isn't delayed. Paris infrastructure is generally solid, but RER B has a mixed reputation during rush hours. Summer? Fine. 8:30am Monday morning? You might be standing shoulder-to-shoulder with 200 other people.

You'll navigate two terminals (probably), follow signs written in French and English, and wait 3-8 minutes for the next train. It's not complicated, but it requires a functioning brain at arrival time. If you're running on fumes, this could feel like a hassle.

The payoff: You save €6 compared to CDG Express, and you go anywhere in Paris (the RER B hits central spots like Saint-Michel and Denfert-Rochereau).

Pro tip: Buy a carnet (10-journey metro pass) for €17.25 right at the airport. Each journey costs €1.73 instead of €1.99. It's not much, but it adds up over a week.

Buses: Cheapest, but Play the Waiting Game

Le Bus Direct and Air France buses run from CDG to various points around Paris. Cost? Around €18 for a single ticket, or €32 round-trip. That's not cheaper than RER B when you factor in convenience.

Buses take 45-90 minutes depending on traffic. 6am? Smooth. 5pm? You're stuck on the Périphérique watching your hotel window get closer in slow motion.

Skip this unless you're hitting a specific drop-off point that's nowhere near the metro.

Uber and Taxis: The Pricey Fast Lane

A taxi from CDG runs €50-70 to central Paris, depending on traffic and your exact destination. Uber is similar. Both beat the bus for reliability but blow past RER B and CDG Express on cost.

Use this if you're arriving with three people and luggage, or if you land at 2am and just want the safety of a direct ride. Otherwise, you're paying for convenience you don't need.

The Honest Recommendation

Budget travelers: RER B. €11.45, takes 35-40 minutes, goes everywhere. Buy a carnet at the airport.

Solo travelers, tight schedule: CDG Express. €17.45, 32 minutes, reserved seat, no thinking required.

Groups of 3+ with luggage: Taxi or Uber. Split the cost, eliminate stress.

Arriving middle of the night: Taxi or Uber. RER B is safe, but the frequency drops and the crowds shift.

The airport experience should not be the most stressful part of your trip. Pick based on your state of mind and budget, accept the small cost trade-offs, and get moving.
