Deep pine forests give way to an exposed limestone plateau as the track advances into the northern reaches of the Sierra de Segura. Leaving the upper Guadalquivir valley behind, the route climbs rugged mountain tracks toward the barren highlands. The track crosses the remote, wind-swept expanses of the Campos de Hernán Perea, a vast karst plateau resembling a lunar landscape at 1,600 meters above sea level. Solitary, weather-beaten pine trees break the horizon where nomadic shepherds graze their flocks. A series of rough, rocky double-tracks leads across the open ridges before dropping into the high mountain basin. The demanding stage finishes in the isolated outpost of Santiago de la Espada, a village shaped by harsh mountain winters and stone architecture.
