Parque Natural Sierra de Grazalema is a UNESCO Biosphere Reserve in the provinces of Cádiz and Málaga characterized by high-altitude limestone mountains and the deepest canyons in Andalusia. It is the rainiest place in Spain due to its unique microclimate that intercepts moisture from the Atlantic. The landscape is dominated by the 'Pinsapar,' one of the few remaining forests of the endemic Spanish fir (Abies pinsapo). The park encompasses several 'Pueblos Blancos' (white villages), including Grazalema and Zahara de la Sierra. Canyoning is concentrated in the Garganta Verde, a massive gorge with vertical walls exceeding 400 meters. Visitors can traverse extensive karst formations, caves, and hiking trails that connect the traditional villages. The region has a long history of nomadic shepherding, which shaped the current scrubland and pasture geography.
