Southeast of Seville and west of Ronda in the Cadiz Province, the scenic Parque Natural Sierra De Grazalema is know for its rocky mountainous areas, green pastoral river valleys and Mediterranean woodlands. You can choose hikes leading through scenic white-washed villages or try the high altitude trek up El Torreon. Keep in mind though that some of the better hikes are in the reserve area that require guides and permits (some free permits are available from the Centro de Visitantes El Bosque).
While the Parque Natural Sierra De Grazalema, and inparticular the town of Grazalema, is one of the most lush place in Andalucia due to high rainfall, it can be quite dry in the peak summer months of July and August. The best time to hike is May, June, September and October.
The trek up El Torreon (1,654m) is a four hour (6km) roundtrip hike. On a clear day, the summit offer exceptional views of the Sierra Nevadas and south into Morocco. To reach the trailhead from Grazalema, head west on A372 (Grazalema-Benahoma Road) for 8km. The trail starts about 100m east of the 40km marker.
Overall, El Torreon is the 12th most popular hiking trail of all 21 hikes in Spain.
