The arid and stripped landscape of the Ribera finds its most pronounced expression in the Real Bardenas, an area of 42,500 hectares on the SouthEast of Navarre where the soil erosion of clays, chalk and sandstone from the Pyrenean folding have created a landscape of Lunar appearance with ravines, high peeled plateaus (flat) and solitary and proud (seamounts) hills.This land belongs to the crown of Navarre which granted its use for winter grazing herds of sheep of the Pyrenean Roncal and Salazar valleys. These valleys still maintain this renewed practice each year on September 18th when the sheep go into the “bardenero” territory with a ritual, known as the “Sanmiguelada”, attracting large audience. In times of Felipe V, the surrounding villages of Bardenas consolidated rights to harvest firewood, resulting in deforestation of the land, and later for the cereal exploitation, a use that continues even today.
The Bardenera vegetation is small and unevenly distributed. The main tree spots are pine and Alappo and they are in the Vedado Eguaras, a nature reserve on the North of the territory, and to a lesser extent, in the Black Bardena, in the southern part.In these plant groupings, pines coexist with large-sized shrubs as “cosojas” “escambron”, juniper or “sabina”. Pine forests are populated by a diverse avifauna including wood pigeons, doves, jays, plus raptors such as kites, eagles and driveways toed or “alcotantes”, and other smaller species such as goldfinches, finches, goldfinches and blackbirds. In the central part or Bardena Blanca, the best known landscape, vegetation consists of scattered tracts of xerophytic scrub of rosemary, thyme, ontino, sisallo and rush, in which small steppe birds such as the skylark live, the Crested Lark, grouse and bargain.
The Bardenas constitute an area of outstanding natural value which exerts an irresistible attraction for many visitors who look for an open space for hiking, cycling route space and, in general, for the enjoyment of nature. The access to territory can be done from any of the adjoining municipalities, usually through farm tracks, but the most common route gets out of the hermitage of the Virgen del Yugo in Arguedas, where you can access the Vedado and Eguaras most distinctive landmarks of this landscape in Blanca, such as the place of Pisquerra, the hillock of Sanchicorrota, the Grates and Rallón.
Privileged place on the gates of the Bardenas of Navarre, it is also close to the monastery of the Olive and the wetland of Pitillas. It has swimming pool, fronton, bakery, bares, shops, supermarket, chemistry, restaurant, etc. There are Aleppo pine. Its parish if the Aunción keeps walls of the early after Gothic nave with marks of stonework. The Gothic vaults are from the XIV century and the tower is blacksmith, from the beginning of the XVIII century. There are left some fragments of the wall, narrow streets, and houses from the XVI century such as the granary of the Diezmos, and some Baroques palaces.
