Hi I am planning a trip to Spain this July and am making my itinerary. I thought I wanted to stay in Northern Spain for a good portion of our 16 day trip because it seemed to have beautiful beaches, but now I am having second thoughts. It seems as though much of Northern Spain, such as the Asturias province, and even places such as Santander, are less touristy? please correct me if I'm wrong. I was really hoping to see Asturias, possibly Gijon or Llanes, but I dont want to go anywhere too off the beaten path. So I know this is odd, but I guess I want to go somewhere more touristy.
Which cities, if any, in Asturias are more urban/touristy, but also have nice beaches? And how are the beaches and tourist opportunities in Santander?
Also, insight on whether our itinerary should look more like: Barcelona (4 nights), Valencia (3 nights), Alicante/malaga (3 nights), Seville (3 nights)
or
Barcelona (4 nights), Somewhere in Asturias- Gijon?(3 nights), Santander (3 nights), Bilbao (3 nights)
Thanks for all the help!
