Hi I'm traveling with my family from Barcelona to Paris in December. What is the fast train that goes there and when do tickets become available? Thank you
It goes twice a day from Barcelona Sants to Paris Gare de Lyon. You can buy it now if it is before Dec 15, when the schedules get revised. From Dec 15 onward, start looking 90 days in advance.
