BiB; thanks, thought so. Looking at that link you kindly provide, isn't Sitges in 3a so outside zone 1 but inside the whole area's ticketing region? Therefore (I haven't researched this yet) I'm assuming there will be an all-day all-zones ticket for bus/tram/train like London's travelcard - not good for airport/Stiges but good for a day out?
**I'll ask about contactless another day...just happy to pick up a card/ticket at the local station!
You are correct. It is outside zone 1 (the city of Barcelona and adjacent municipalities) but in the zonal area covering the Barcelona Metropolitan Area. There is also a metropolitan fare zone, introduced three years ago, in which zone 1 integrated (i.e. multimodal) tickets are valid. Articles suggest this was done due to political pressure.
For the whole zonal area, integrated zonal day tickets, 10 journey tickets and passes, but no integrated single tickets are available.
Sitges - Barcelona
Integrated (multimodal) tickets - 3 zones
20.10 T dia - 24-hour pass
30.50 T casual - 10 journeys (max. 1 h 45 min per journey)
75.60 T usual - monthly pass
Local 'suburban' (not 'regional') Rodalies trains only - 3 zones
3.85 single
24.20 10 journeys
47.05 Monthly pass
For suburban services, the airport is in zone 4 (presumably to increase revenue for travellers heading into Barcelona), so you will need a four-zone mode-specific single between Sitges and Barcelona Airport Terminal 2 costing 4.60 EUR. For the local Barcelona public transport operator (ATM), it is in zone 1, but single and 10-journey tickets for zone 1 are not valid, and a special, higher airport fare applies (though zone 1 ATM-specific passes are valid to the airport on ATM services). For the purposes of integrated (multimodal) ticketing, the airport is in zone 1, but T casual 10-journey tickets are not valid for travel to the airport on the ATM metro service - all other tickets are fully valid to the airport.
A three-zone T dia at 20.10 EUR would also cover you between Sitges and the airport.
The integrated (multimodal) ticket for all 6 zones for 24 hours (T dia) costs 28.15 EUR. This allows you to travel a significant distance, for example almost 100 km out of Barcelona on the line to La Tour de Carol.
Map of the integrated fare network
None of these tickets allow you to travel on Media Distancia (Middle Distance) or regional rail services. Both the regional rail services and the suburban services run under the Rodalies brand, and the distinction is not obvious. The suburban lines are R1, R2, R2 Nord, R2 Sud, R3, R4, R7 and R8. The regional services are R11, R12, R13, R14, R15, R16 and R17.
You can find the information you need on the
Rodalies website.
