How to reach Lleida:
The best way to reach Lleida is from Barcelona El Prat airport, then from there you can have different options:
- Train (recommended): You can reach Lleida with high speed train (AVE) in approximately 1 hour from Barcelona Sants train station. Tickets and time schedules are available in the RENFE (Spanish railway) website http://www.renfe.com/. The line has a security and baggage check before the access to the train gate, therefore is recommended to arrive at least 20 min the train departure.
To reach Barcelona Sants station you can:
Airport train: take the R2 train line directly from the Airport train station located 200 m outside terminal T2 building (please be aware that most planes today arrive to T1, and to go from one terminal to the other you need to take a bus). Both infrastructures are connected by a covered footbridge. Train departures from the airport are every 30 min and takes around 20 min to arrive at Barcelona Sants. Purchasing the AVE or Intercity ticket to Lleida, the airport train R2 to Barcelona Sants is already included in the ticket price. In this case you have to type in the vending machine at the airport train station, the Combinado Cercanias code printed in the train ticket or scan the ticket directly at the gate of the regional train
- Taxi: Trips to the train station are fixed at 30 € – 35 € and the required travel time under light traffic is around 15 minutes.
