A UNESCO biosphere reserve of 530 square kilometres covering some of the most dramatic limestone country in Spain. Peaks reaching 1,650 metres, deep gorges, cave systems, oak and pine forests, and one of the largest griffon vulture colonies in Europe.
The park information centre in Grazalema (on Calle Las Piedras) issues hiking permits — required for the most sensitive routes including the Pinsapar, the Garganta Verde gorge, and the Torreón summit. Apply a few days ahead in high season; the daily quotas fill quickly. Closed Mondays.
