Planning a trip in and around France/Europe:
The best way to explore Europe is by train. EU rail (for overseas visitor) and Inter Rail pass (for European resident) are best options. You can find further information on this unofficial guide about euro-rail/inter-rail pass. Note that if you have been staying in Europe for >6 months then you can buy an Interrail pass, which is normally cheaper than the Eurail pass. Also note that the interrail pass is not valid in the country of residence.
