No, the Eiffel Tower is not visible from the ground at Charles de Gaulle (CDG) Airport because it is located approximately 26 to 30 kilometers (16 to 19 miles) away. Furthermore, the airport is surrounded by low-lying hills, terminal buildings, and airport infrastructure that block any distant sightlines of the central Paris skyline. Even from the air, spotting the Iron Lady during takeoff or landing is quite difficult. Most flight paths at CDG approach from the east or west, whereas the Eiffel Tower is situated to the southwest of the airport. For a passenger to see it, the aircraft would need to be at a specific altitude and on a very particular flight path that passes closer to the city center, which is rare for standard commercial arrivals. If you have a layover at CDG and want to see the tower, you will need to take the RER B train or a taxi into the city, as there is no "airport viewpoint" that offers a glimpse of the iconic monument.
