Barcelona to Porto roadtrip help
 

Hello i am currently on a roadtrip from barcelona to porto it was a last minute idea so it is not really planned thoroughly. So far we have visited
Barcelona 4 days
Zaragoza 1 day
Pamplona 1 day
San sebastian 2 days
We have just arrived to bilbao today. We are not sure where to go from here we are thinking santander but are not really convinced if it is worth visiting we plan on traveling until the 25. What towns, beaches, local secrets, places to stay would you advise. Any insight will be greatly appreciated. Thank you in advance!!

We followed a similar itinerary in the opposite direction and enjoyed these places..
There are paradors in Leon and Baiona. Pousadas in Guimares and Viano do Castelo.
Spain: Comillas, Ribadesella, Leon, Santiago de Compostela, Baiona,
Portugal..Viano do Castelo, Ponte de Leon, Guimares
