Source of the Palancia River Nature · Bejís, El Alto Palancia, Castellón Image of Bejís, not of the place itself. The Río Palancia rises in the sierra de El Toro and flows 90 kilometres through the provinces of Castellón and Valencia before reaching the sea near Sagunto. In its upper course, which crosses the municipality of Bejís, it maintains waters of great purity, and it is from this town onward that discharges from downstream settlements begin to be noticeable. The basin, covering 976 km², sits on limestone, sandstone, clay, marl and gypsum, giving it a varied landscape and rich biodiversity; owing to its high ecological value, the headwaters of the Palancia are listed in the Inventario de riberas, márgenes y otros espacios hídricos de interés as a natural area to be protected.
