IRB Castro buses
IRB Castro runs the VAC-220 line, the bus linking Castro Urdiales with Bilbao and Cruces (Barakaldo).
It is the direct connection between eastern Cantabria and Greater Bilbao: departures leave from Termibus, stop at Cruces — next to the hospital — and reach Castro Urdiales, spread across the day for work, study and medical trips. Tickets are sold at station counters or on board.
Sarebus shows IRB Castro timetables and the routes it runs, and lets you compare them with other operators when there is more than one option for the same journey. From there you can open the official IRB Castro information.
