There is no direct train from Orly Airport to the Eiffel Tower. The most common public transit route involves two steps: take the Orlyval shuttle to Antony station, then board the RER B line to Champ de Mars–Tour Eiffel station (about 30–40 minutes total). Alternatively, the OrlyBus runs to Pont de Sèvres, connecting to Metro Line 10 (roughly 1 hour). Taxis or rideshares offer a 20–30 minute door-to-door option, traffic permitting.
