No, the Paris Metro is not included in the Interrail or Eurail Pass. The pass covers travel on the national rail network (SNCF) and certain regional trains, but it does not extend to local urban transport systems like city buses, trams, or the underground Metro. This also applies to the RER trains (suburban express) when traveling within central Paris; however, your Interrail pass may be valid on certain RER lines if they are operated by SNCF, but this is often confusing for tourists and generally not worth the risk of a fine. In 2026, the best way to navigate Paris while Interrailing is to purchase a "Navigo Easy" card or use the "Bonjour RATP" app to buy individual T+ tickets or a day pass. Note that while the Metro is excluded, your Interrail pass does provide discounts on some international bus routes and ferries, but for city-center transit in Paris, you must pay separately.
