Jaen is located in the skirts of a mountain, so you need to walk up and down hill frecuently. My piece of advice: wear comfortable shoes!
Jaén se encuentra en la falda de una montaña, por lo que es preciso ir cuesta arriba y cuesta abajo frecuentemente. Mi consejo: ¡usad zapatos cómodos!
The red land of Jaen, origin of the finest olives, offers a beautiful lanscape at sunset. My dumb camera could not record the marvelous colours that Jaen gave me as present when I drive south from Madrid in my quest for "La Alhambra". Some day I will be back and perhaps the skies of Andalucia will be leninent and would give me a second chance to see ans experience that peaceful view.
An extraordinary a beautiful poem by Migue Hernandez written in the middle of the Spanish Civil War opens my homage to Jaen. Wish I could translate it in all its strength and splendor.
Favorite thing: In Jaén, olive oil might as well be liquid gold that's pressed out of the black crude during each year's olive harvest. Jaén Province is Spain's olive oil capital and the biggest olive oil producing region in the world.
