Towards Bilbao

Walk down along the Autovia S10 until after the roundabout 'Enlace de la Marga' and a bit further (some 200m) to the gas station. From there you can either try signs (unlikely) or talk to people. You need to get at least to the next gas station on the A8 (not too far away), at Hoznayo. Anywhere from there you will make it to Bilbao.
