I am in the process of stumbling through an itinerary for our month long October trip to Portugal and southern Spain. We fly in and out of Lisbon so have decided that a circular route will work (except we will go north to Porto then come back south through Coimbra, Evora..over to Seville, Granada, Nerja, Ronda Malaga...then go to the Algarve and train back to Lisbon. I have searched without much luck about how to get to southern Portugal from the south of Spain. This is an ambitious itinerary. Any suggestions and information would be greatly appreciated.
