Charles de Gaulle Airport to Paris in 30mn by the express train RER link
Getting to Paris from Charles de Gaulle Airport is a breeze thanks to the express train RER, the second most popular mode of transport after taxis. Not only is it convenient, but it’s also fast and economical.

Here’s what you need to know:
The RER takes you from CDG Airport to the heart of Paris in just 25 to 35 minutes.
For destinations on the Rive Droite – Right Bank of the Seine, your stops will be Gare du Nord (TGV station) and Châtelet-les-Halles.
If you’re heading to the Rive Gauche – Left Bank, you’ll get off at Saint-Michel-Notre-Dame, Luxembourg and Denfert-Rochereau stations. It’s also at Denfert-Rochereau that you can catch buses or the RER to Orly Airport.
And the best part? It’s very affordable. Plus, your express train RER ticket doubles as a metro pass, so keep it for the rest of your journey. While it’s an economical option, keep in mind that you’ll have to manage your luggage on the train. For families or groups of four, however, it’s still more cost-effective than a taxi. So, if you’re looking for a quick and affordable way to get to Paris from CDG airport, hop on the RER and prepare for a hassle-free journey into the heart of the city.
