Our app currently suggests a connection to Barcelona first when traveling from San Sebastian, Spain to Bordeaux, France. However, this route is quite long and takes over a day to complete. We want to let you know that there is an alternative route that is not yet displayed on our timetable. The only catch is that it requires a 11-minute walk, which is not currently factored into our schedules. Rest assured, our team is actively working to include this route in our app as soon as possible.
In the meantime, we suggest that you look at the itinerary on SNCF's website and divide the journey using the app.
