On entering the Natural Park, you will see the silhouette of Alanís standing out against a gentle slope. Its medieval castle at the top and, next to it, the chapel of San Juan are the most distinctive landmarks of the town.
Cazalla is located in the heart of the Natural Park. Its outstanding cultural importance is based on its history, which has provided it with a unique monumental and ethnological wealth.
Human presence in the area of El Pedroso can be dated back to the Palaeolithic period, thanks to the discovery of flint arrowheads. The Neolithic megalithic culture was also present in the area, as has been confirmed by the recent discovery of a tholos. El Pedroso, like most towns in the area, gained importance after the Reconquest.
The origins of this town date back to Roman times. It was a small village, whose main source of wealth came from the marble quarries, called Pagus Marmorarius, which translated from Latin means "village of the marbles".
The walk begins and ends in the village of El Pedroso and crosses the curious area of granite outcrops known locally as montonás. At the beginning, on the right, there is an oil mill, closely followed by the remains of old granite quarries.
This walk through the surroundings of Almadén de la Plata passes through areas of grassland, olive groves, dehesa and riverbanks, running alongside the Las Calzadillas stream.
The walk follows a section of the Vía Verde de la Sierra (Greenway of the Sierra), an old railway line between the provinces of Cadiz and Seville that has now been converted into an eco-tourist trail.
