SUMA is a zonal system for public transport around Valencia, composed of zones A,B,C,D and +.
I hold a T1+ which allows unlimited travel on zones A, B and + for 24u
I can find zones on the Valencia's metro, Cercanias, MetroBus.
EMT is supposedly part of the system but from my Googling, I can't find what borders are for EMT. Notably whether the Pinedo neighborhood is in zone A or B?
Or, is it alike London where there are no zones for buses?
