Designated a Unesco Biosphere reserve in 1977, the Sierra de Grazalema was declared the first natural park in Andalucia in 1984 and is one of Spain’s most ecologically outstanding areas. The 51,695ha park is famous for its spectacularly rugged limestone landscape of cliffs, gullies, caves and gorges. By far the most impressive gorge is Garganta Verde, with its exceptional griffon vulture colony and rocky walls that tower vertically for 400m. Andalucia’s largest cave system is also here, the Hundidero-Gato with its biggest cavern measuring 4km long and an entrance of 60m tall.
The region is well known for being the rainiest place in Spain, with an annual rainfall of 2,200mm, which means that the 1,300 Mediterranean plant species that have been registered here, many of them endemic and some of them unique to the Sierra, flourish.
At times when fire risks are greater (July to September) walks to some of the areas are closed. For walks in the rest of the park, except for Sendero Garganta Verde, you must go with an authorized Turismo Activo company (details from the information offices listed in our information section). For the rest of the year, you need to obtain permits from the El Bosque information office. Grazalema is about 40km away from us.
