After so many visitors interested in visiting Seville, Ronda, Málaga, Córdoba, Barcelona, Madrid, Toledo, Segovia...I would like to propose some alternatives much more off the superbeaten places above:
- Northwest: Ourense and the Ribeira Sacra region, León, Zamora, Lugo (inland and coastal), Valladolid.
- North: Burgos, Vitoria-Gasteiz, Salt Valley of Añana, Rioja wine region (the Oriental side is the least visited), San Vicente de la Barquera, Llanes and the coastal towns on the way to Galicia, Cantabria (I´d skip Santander). The valleys of Elizondo, Baztán and Roncal in Navarre. Otxagabia and neighboring towns.
- East: Gallipienzo, Uxue (or Ujué), Castle of Javier, Zaragoza is a must-see (big city), Estella, Tudela and the Bardenas Reales, Tarazona, Daroca. (I´m leaving Catalonia out of this list as I´m not that familiar with this area). Teruel and its province. Alcañiz and Albarracín.
- South East: Valencia is also a must, Alicante, Tarragona and its Roman amphiteatre and more, Morella. The delta of the Ebro river and the Albufera.
- South: Huelva, an amazing province next door to Portugal and a hidden gem. Jerez de la Frontera. Jaén, the capital, Úbeda and Baeza. Inland province of Murcia. Alpujarras region in Granada.
Hope some of these ideas help to plan a new visit to this heterogeneous, diverse and multicultural country!
