Although somewhat off the beaten track, Jaen is an interesting city with some nice attractions, as well as some great mountain areas in the vicinity. The main attraction is the Cathedral Santa Catalina, an upcoming UNESCO world heritage site. You can also check out the Castillo de Santa Catalina, which is positioned right next to the Parador de Jaén Hotel. There are walks into the mountains behind Jaén leading from the road that goes up to the castle. As a major olive growing area, you can also join a guided Olive Mill tour in the vicinity (in Begijar, 30 mins away) – more interesting than you might expect.
