The rugged, pillar-like peaks of the Parque Natural Sierra de Grazalema rise abruptly from the plains northeast of Cádiz, revealing sheer gorges, rare firs, wild orchids and the province's highest summits, against a beautifully green backdrop at altitudes of 260m to 1648m. This is the wettest part of Spain – stand aside, Galicia and Cantabria, Grazalema village logs an average 2200mm annually. It's gorgeous walking country (best months: May, June, September and October). For the more intrepid, adventure activities abound.
The 534-sq-km park, named Spain's first Unesco Biosphere Reserve in 1977, extends into northwestern Málaga province, where it includes the Cueva de la Pileta.
