On what level in the Gare Montparnasse do I activate my France rail pass? Is it one of the ticket offices on level 2? If so, which office would I use on the day of my first train trip? Is that also the same level for the TGV trains?
Thanks,
John
There is one on Level 2 of Hall 1. See https://www.gares-sncf.com/sites/default/files/field_plan_files/2018-02/pmp_h1_n-01.pdf
Thanks so much for the info!
