I want to ask about how navigo pass work in my case.
I stay near the Bures sur Yvette RER B station (Zone 5) which is in the opposite end of CDG airport.
Can I use navigo one day pass for zone 4-5 to go to CDG airport by RER B?
Or I have to buy the pass for zone 1-5.
You will need a 1-5 zone Navigo pass for a trip from Zone 5 to Zone 1 back out to Zone 5. All RER trains go through the center of Paris, Zone 1. There isn't a circular train route around the city like there are in many cities. If you were to buy a single-use RER ticket, it would cost 14.70€ for this trip. A 1-day 5 zone Navigo Jour day pass is 17.80€ so if you only have to make one trip that day, a single-ticket would be cheaper.
