The Bardenas Reales constitute a semi-desert area of more than 41,000 hectares that extends through the southeast of the Foral Community of Navarra and part of the Autonomous Community of Aragon. Its orography, the practically lack of vegetation, the typology of the terrain and the erosion suffered by the passage of time make up a unique landscape in Spain and with undoubtedly different photographic possibilities. The Mexican poet Abel Pérez Rojasa recited that "Sunflowers are not intimidated despite the hidden sun, the strong wind and the plump clouds". The sunflower shines by itself, it composes in solitude and in company and colors the fields with the color of the sky and the earth.
