I will be traveling to Spain in October 2017 and will be starting and ending my trip in Barcelona. I plan to spend just 2 days in Barcelona, as I have been there previously, and will then have 5-6 days to spend in other parts of Spain. I am debating between doing a northern route that may include San Sebastián, Bilbao, and the Basque Country versus going to the south and spending time in Granada to see, primarily Alhambra, and also potentially visiting Córdoba. (I have already been to Seville so I do not plan on going back there on this trip.) A third option also occurred to me which would be to fly to San Sebastián for a couple of days, then fly to Granada for a couple of days, and then fly back to Barcelona. My questions are these:
1) Between the northern option and the southern option which would you recommend, particularly for October? I realize it's a personal question, but the two of us like both of what those places would have to offer (we're foodies so San Sebastián would be appealing but would also appreciate the castles, culture, and experiences that Granada would offer).
2) Would you recommend doing only one of the two options (which might allow us to do some side trips to places like Bilbao or Granada or is it possible to combine spending 2-3 days in San Sebastián with 2-3 days in Granada, flying between those cities and Barcelona?
Thanks in advance for your help.
