If you talk about where the Eiffel tower is specifically, she
stands on the Champ de Mars in front of Jena bridge over the river
Seine.
The question is how to reach the Eiffel
tower is also very simple: you have to navigate to the station
Bir-Hakeim line 6 of the Paris metro. Another option would be to
Trocadero station line 9. Bus routes on which you can reach the Eiffel
tower: 42, 69, 72, 82 and 87.
