This walk on the southern slope of the Sierra de Crevillent passes through an arid environment with reddish rock formations from the Triassic period. Furthermore, the Peña Negra site is visited, which is linked to the ancient city of Herna. Information panels provide insight into this ancient Iberian settlement. Along the way you will come to a restored shepherd's hut. These Xosses were built with the so-called dry stone construction technique and have been declared a UNESCO World Heritage Site.
