If you’re a returning tourist who plans on relying on public transportation frequently and you will be in Paris for a week or more, the Navigo Pass is great choice in terms of convenience and cost. The Navigo pass allows unlimited rides on public transportation within Zones 1-5 including the airports. Unlike the tiny cardboard t+ tickets that you have to insert, the Navigo pass is a plastic card that you simply swipe over the reader at the turnstile, which makes it much more convenient than fumbling with the t+ ticket. If you’re traveling on the metro or buses frequently, the Navigo Pass will end up the cheaper choice than purchasing Carnet after Carnet of individual tickets. The only downside to the Navigo pass is that it’s only valid from 12am Monday to 11:59pm Sunday. The 7-day span cannot be customized to when you arrive to Paris, so if you arrive on a Thursday, you might want to consider the Paris Visite Travel Pass below!
