my Schedule is below
i will arrive at CDG at 4pm 7th Mar20 and i have my return flight at 10:15am on 8th Mar20.
I wanted to go to Eiffel Tower and near by places and planning to return to airport early in the morning.
please suggest what are budget train tickets i can buy. And also help me the near by metro stations to most visited places near Eiffel tower.
All Paris transportation passes count a full day of use at midnight, regardless of when you start using it, so unfortunately there's no easy budget Paris transit ticket that works overnight for you. To go from CDG to Paris (and back) I'd recommend single-use RER tickets. Then if you plan on making more than 4 bus or Metro train rides, in Paris center, before midnight or during the next day, then buy a Ticket Mobilis 1-2 zone day ticket for each day.
To get into Paris I'd recommend taking the RER B from CDG to Paris until St Michel Notre Dame station, then transfer (using same RER ticket) to RER C to Champ de Mars Tour Eiffel and beginning your sightseeing there.
Paris Metro line 6 will take you to Arc de Triomphe. Then Paris Metro line 1 will take you to Champs Elysee / Place de la Concorde / Tuileries / Louvre / Notre Dame.
