El Bosque is the 'gateway' to the Sierra de Grazalema Nature Park: not only due to its location but also because the park's office (where to get permission for restricted hiking trails) is here. It's a small village of 2000 inhabitants, but 25 bars/restaurants and several supermarkets. It's also ideal if you want to explore the region's cultural attractions and beautiful towns, such as Arcos de la Frontera, Ronda, Jerez de la Frontera, Cádiz and Seville.
Sierra de Grazalema, a UNESCO-Biosphere Reserve, is perfect for several kinds of outdoor sports: paragliding, hang gliding, canyoning, caving, horseback riding, cycling, climbing and - of course - hiking. With several peaks of over 1000 meters altitude, the park offers numerous beautiful routes.
