Barcelona, Spain
Upon arrival, follow the signs to the Consigna (left luggage) facility to check luggage into storage. Storage costs €6 for up to 2 hours or €10 for up to 24 hours per bag. There are cheaper storage options nearby, but they require leaving the station and crossing a small park.
From the Barcelona-Sants Station, catch the Metro L5 (Blue Line) for 5 stops to Sagrada Familia. Cercanias (local trains within Barcelona) tickets can be purchased from red and grey ticket machines with cash or card.
If you travel on AVE (high-speed) or Larga Distancia (Long Distance) trains, your ticket includes Combinado Cercanías, which will allow you to travel on Cercanías (Suburban), Rodalies (Commuter) and the Alicante TRAM network. You can use the Combinado Cercanías from 4 hours before departure and up to 4 hours after arrival at your destination. Purchase a Combinado Cercanías ticket at self-service machines and station ticket offices, scanning the barcode or entering the 5-character code on your ticket.
