As a foreigner in France, can I buy the Forfait Navigo Month? It's a month-long pass that allows you travel throughout all 5 zones of the greater Paris metropolitan area (10 million people). With it, you travel free (at no extra charge) on the weekends (& all days in the summer, until August 18) throughout the entire Paris metropolitan area, not just within the city. It's the result of the rail network's new "dezonage" policy.
I don't understand your reference to August 18 and I know nothing about a "dezonage" policy. Yes, you can buy the monthly version of the Forfait Navigo. It's good for a calendar month (from the first day of the month to the last). You can buy it for a variety of zones so you don't have to pay for all five.
John, you can perfectly buy a Navigo monthly pass, anyone can, but some of your information is inaccurate. First, Navigo is not a automatically a 5 zones pass. The number of zones it covers depends from the price you pay. The 5 zones Navigo costs 104,70 € a month. Check prices for the different zone combinations at
http://www.ratp.fr/fr/ratp/c_20597/forfait-navigo-mois-et-semaine/ This pass allows you to travel without limitations on the whole Metro, RER and Transilien networks (except Orlyval) in the zones you paid for, without buying tickets for each trip. Then "Dezonage" doesn't mean what you say. It means that you can go to any zone on the weekends/summer even if your pass doesn't normally cover this zone. If you have a 5 zone pass already, dezonage doesn't give you anything more. It is worthy if you buy a zone 1-2 pass, stay in Paris during the week and plan trips in other zones (Versailles, for example) during the week-end and/or summer days. If you come between July 13 and August 18, don't bother buying a 5 zone pass, buy a much cheaper Zones 1-2 pass. Also be aware that the monthly Navigo pass starts on the first day of the month and lasts until the last day of said month. Depending on your arrival and departure dates, this can be a major inconvenience. Hope this helps, Rif
