My tip“Set aside at least two days: the town of Cazorla, the Borosa river, and Segura castle; and a boat trip on the Tranco dam.”
The largest natural reserve in Spain (over 200,000 hectares), with the source of the Guadalquivir, pine forests and hanging villages such as Segura and Hornos with their castles, and home to red deer, ibex and the bearded vulture.
Moderate effort, needs a car
By car only; long winding mountain roads. Trails range from easy to hard. Weak coverage in the valleys.
