Yes, there are two primary direct train options connecting central Paris to Charles de Gaulle (CDG) Airport. The most common is the RER B regional express line, which runs frequently from major hubs like Gare du Nord, Châtelet-Les-Halles, and Saint-Michel. The journey typically takes between 30 and 45 minutes depending on your starting station and whether the train is an express or local service. Additionally, high-speed TGV trains connect CDG directly to other major French cities and occasionally run short hops from stations like Marne-la-Vallée. For most travelers in the city center, the RER B remains the most reliable and direct budget-friendly link, with trains departing approximately every 10 to 20 minutes throughout the day.
