Good line N°4… always crowded, a bit oppressive, but goes every where you need to
Line 4. 4 stops to the Gare du Nord, for Eurostar and RER (fast metro to Charles de Gaulle and Orly airports).
Metro 4: take this line to go to Gare du Nord and then the suburban train RER B to go to Charles de Gaulle Airport.
