Established as a natural park in 1999 and as a UN Biosphere Reserve in 2000, the Bárdenas Reales is a desiccated landscape of blank tabletop hills, open gravel plains and snakelike gorges covering over 410 sq km of southeastern Navarra. As well as spectacular scenery, the park plays host to numerous birds and animals, including the great bustard, golden eagles, Egyptian and griffon vultures, numerous reptiles, mountain cats and wild boar.
