Avoid the rush-hour !
We were a little late in arriving in Jaen - it was almost noon when we drove into the city. The traffic was very heavy and there were road-works holding up the traffic. We didn't have a map of the city (MOST unusual for me) and so headed towards the centre, hoping to spot a sign for a car-park, or if we were really lucky, find a space on the street. Spotting signs was much harder than usual, and we soon found ourselves stuck in one-way streets, with no way of reversing our general direction, or doubling back through side streets. In the end we gave up, and headed off to Banos de la Encina - one of our favourite off-the-beaten track places, where we hardly saw another car and had a good lunch.
We returned late-afternoon, before the traffic built up, and headed for the Parador and castle. On the way back, we managed to find the Cathedral quite easily, but of course we were too late - it wasn't open - and we still couldn't park. Still as Liz says "always leave something to go back to" !!!
If you want to visit this area of Andalusia during the Spring, make sure that you do not suffer from allergy to the olive pollen.
You will be surrounded by olive trees and their pollen is quite aggressive for allergic people.
