How much is Complement de Parcours?

Question

I am going to be travelling into Paris. I land in CDG but am not sure of how to get to Paris (Gare du Nord). I am planning to buy a Navigo Decouverte with zones 1-2 loaded on. I also am travelling to Versailles and back. I have heard about Complement de Parcours and have seen that they give discounts on tickets. I am travelling in a group of four (me included) and I was wondering if I am better off getting the ND with zones 1-2 or zones 1-5?

What is the cheaper option, a Navigo Découverte zone 1-2 plus a complément de parcours to Versailles, or a Navigo Découverte zone 1-5?

Answer 1

To go to Versailles-Château-Rive-Gauche from the center, you only need zones 1-4. A Navigo semaine for zones 1-4 is 32 € or 11.60 € more than a zones 1-2 pass. According to the map on Wikipedia, the last station in zone 2 on RER C trains to Versailles is Issy-Val-de-Seine.

A “origine-destination” ticket from this station to the Château costs 1.80 € and this should also be the price of a “complément de parcours” if you have a Navigo for zones 1-2. A round trip would therefore cost you 3.60 €. Even twice the full fare from the center (3.35 € times two so 6.70 €) is still under the difference between the Navigo semaine zones 1-2 and 1-4 prices.
