CDG sits about 25 km northeast of central Paris, and there's no single "best" way in — it depends on how much luggage you're carrying, what time you land, and how much you value predictability over price. Here's how the four main options actually stack up.
RER B train — cheapest, but not effortless
The RER B runs directly from the airport into central Paris (Gare du Nord, Châtelet, Saint-Michel) in about 35–50 minutes. It's the cheapest option by a wide margin, but it comes with real trade-offs: stations involve stairs and escalators that aren't always working, trains can get crowded, and the platform-to-platform walk with luggage isn't fun after a long flight. It's a solid choice if you're traveling light and landing at a reasonable hour.
Taxi — simple, but pricing surprises happen
Paris taxis from CDG operate on a flat-rate system to the Right or Left Bank, which sounds simple — but surcharges for extra luggage, nighttime pickup, or a fifth passenger can add up before you realize it. You also don't know your driver, your car, or your exact wait time until you're standing in the taxi queue, which can be long during peak arrival windows.
Shared shuttle — cheaper than a taxi, slower than everything else
Shared shuttles split the cost across multiple passengers, so they land between the train and a private transfer on price. The catch is time: you're on the shuttle's route, not yours, so multiple hotel drop-offs before yours can turn a 45-minute trip into 90.
Private transfer — the option most people actually want, once they know it exists
A private transfer means one car, one straight route to your address, and a fixed price agreed before you land. The driver tracks your flight, so a delay doesn't cost you anything extra, and there's no queue to stand in at arrivals — just a name sign waiting for you. It costs more than the train, but for a first arrival in a new city, after a long flight, with luggage, it removes the one part of the trip most likely to go wrong.
If a private transfer sounds like the right call for your trip, you can see live pricing for the CDG-to-Paris route and book ahead of time.

GetTransfer vs Kiwitaxi: which one actually gets you cheap transfers?
So which should you actually pick?
If you're landing early in the day, traveling light, and comfortable navigating a train station on little sleep — the RER B will save you money and get you there fast. If you're landing at night, traveling with a group or heavy luggage, or just want one less thing to think about after a long flight, a pre-booked private transfer is worth the extra cost. The shared shuttle rarely wins outright — it's usually only worth it if you're traveling solo on a tight budget and the train genuinely doesn't work for your route.
