Lebrija-Las Cabezas Natural Reserve
A total of six lakes make up this 949ha reserve: Pilón, Taraje, Cigarrera, Peña, Galiana and Charroao, in order of size with Pilón being the largest. The Laguna del Taraje is the only lake with water in all year round. These six lakes are the only ones left of a much bigger series of lakes that used to occupy this area around the Seville/Cadiz provincial border, which have dried up due to increasing irrigation for agricultural activities.
