Hello guys, I will have a day layover in CDG airport and I am planning to use that time to have a glimpse of Paris. I would like to see Eiffel tower, Notre dame and Champs Elyse street. Airport is in zone 5 and other attractions in Zone 1. So I would like to know which ticket I have to buy to visit just these places with the present ticket cost.(including CDG to & fro). Thank you in advance.
