Jaén is one of the provinces of Andalusia, Spain. Being undeservedly the less frequented of them, Jaen still rewards its visitors with the unique view of the olive trees covering all hills (Spanish: cerros) in sight, as well as an incredible value for its monumental heritage and unspoiled nature.
Jaén is inevitably linked with the olive trees landscape and the olive oil production. In fact Jaén is the main producer of olive oil in the world and the industry has a huge importance for the local culture.
Besides the olive trees Jaén also hosts the biggest protected area of Spain and second in Europe (behind the Black Forest in Germany), the Natural Park of Sierra de Cazorla. There the olive trees are abruptly substituted for green vegetation and the Guadalquivir river, and deers, wild boars and other animals are easily spotted during the hiking routes.
The closest airport is Granada. This airport is in fact called Granada-Jaen and its supposed to serve the latter too, but the city of Jaen is located around 100 Km from the airport. There are no direct buses from the airport to Jaén anymore so a change in Granada is needed.
The other train station in the province is Linares-Baeza, located in the outskirts of Linares. It has slightly better conections to the region and its closer to Úbeda and Baeza. Outside the station there is a bus stop where buses to those two attractive towns depart.
RENFE  has info about times and prices.
If coming from the north the highway A-4 (also known as Autovía del Sur or Autovía de Andalucía) links with the A-44 (Autovía de Sierra Nevada) in Bailén and passes throught Jaén, going south to Granada.
With only two train stations (Jaén and Linares-Baeza) trains are not the most appropiate way to travel around. Even if arriving to Linares by train another way of transport is needed to reach either city itself. Line buses link the main cities and towns but the frecuency may be dissapointing.
A car is recommended to move around, especially for Sierra de Cazorla.
The Renaissance-style palaces and churches of Úbeda and Baeza are included in the UNESCO Heritage list and are worth a visit. If interested in nature, Sierra de Cazorla offers plenty of opportunities.
Restaurants are limited, being tapas bars the main choice for eating. Local dishes include the flamenquín, most known in Cordoba but actually originated in Jaén, and Andrajos, a stew with rabbit, hare or cod. Blood sausages, goat, trout and game are thoroughly available.
Unsurprisingly olive oil is widely offered and served.
Wines with a certificate of origin include Bailén, Torreperogil and Sierra Sur de Jaén.
Andalusian Spanish is the main language. Hotels and tourist attractions often have English speaking staff.
