The Desfiladero de Despeñaperros, a dramatic, deep gorge cutting through the Sierra Morena, is traditionally considered the main gateway to Andalucía from the north. The hilly and beautiful country straddling the gorge is the Parque Natural de Despeñaperros: for information on the park and walking routes, visit the Centro de Visitantes Puerta de Andalucía on the west side of exit 257.
