Starting route
Direct TGV to Sants
Paris → Montpellier → Perpignan → Barcelona
The direct TGV links Paris Gare de Lyon with Barcelona Sants. The map sketches the southern France corridor rather than every station call. Search the two endpoints to compare departures and any alternatives offered for your date.
Another way
A night in Montpellier
Paris → Montpellier → Barcelona
Break the trip in Montpellier and continue the next day. Saint-Roch and Sud de France are different stations, so inspect the arrival and departure when choosing a stay. This option changes the pace of the trip rather than promising a faster connection.
