line DO04, via Zarautz on request
Pesa
from €13.65
The parts people get wrong. Each one links to where we checked it.
Easy to get wrong
The DO04 does not call at Zarautz unless you ask. Pesa's own line sheet says the bus will only stop there if the driver is told when you board, and that without asking it will not stop.

Where to go
The two DO04 stops at Bilbao airport are on different levels: the bus leaving for San Sebastián goes from the arrivals level, while the one arriving from San Sebastián sets down on the departures level.

Fixed fare
The San Sebastián to Bilbao airport single is €13.65 by day and €14.75 at night without a card — by a wide margin the most expensive airport bus fare in this catalogue. A discounted Mugi card price exists, and the line was folded into the Mugi system in March.

Easy to get wrong
There is no line DO09. The Bilbao airport service from San Sebastián is the DO04, with a second night line, the DO44G, on the same corridor.
