Parque Natural Sierra de Grazalema is a magnificent area for walkers and those interested in birds. It is a UNESCO biosphere reserve. The landscape is very varied with jagged peaks, woodlands, valleys and almond groves. Birds that may be spotted include vultures and eagles. For some areas of the park, it may be necessary to obtain a permit. These can be arranged from the visitor centre in El Bosque, the entrance to the park.
