I have been seeing much conflicting information about the new Paris Metro tickets/passes available for 2025 and could use some guidance.
We will be in Paris in a week, arriving on a Monday at CDG and leaving on Friday also from CDG. The only other time we will be using an RER train will be to go to Versailles, otherwise I assume we will just take the Metro 2 or 3 times a day and possibly the Funicular at Montmartre. I was thinking of buying the Navigo Decouverte pass but then have seen posted online conflicting information about that pass still being available. Is that still available? Is there a better option for this type of itinerary? At the moment, I don't plan on having a pass on my phone and prefer the plastic card. If Decouverte is still available, how does the whole photo thing work? Do we bring photos from home or take them at the metro? Thanks for your help!
