To get from Paris Charles de Gaulle (CDG) to the Eiffel Tower in 2026, you have several reliable options. The most budget-friendly is the RER B train; take it to "Saint-Michel Notre-Dame" and transfer to the RER C train toward Pontoise or Versailles, alighting at "Champ de Mars - Tour Eiffel" (approx. 75 mins, €11.80). As of March 1, 2026, a new Express Line 9517 bus has replaced the old Roissybus, offering a direct route to the city center for a lower fare of around €4.20 when combined with a metro ticket. For maximum convenience, a taxi from the official rank has a flat rate of €60–€65 to the Left Bank (where the Eiffel Tower is located) and takes 45–60 minutes depending on traffic. If you are arriving at Orly Airport (ORY), the "Orlyval" shuttle to "Antony" followed by the RER B and C is the standard rail route, while a taxi to the Eiffel Tower from Orly is cheaper at a flat rate of €44.
