The Bardenas Reales Natural Park, located in southeastern Navarre, presents a stark and captivating landscape of semi-desert terrain. This unique environment, shaped by erosion over millions of years, features dramatic rock formations, canyons, and plateaus, offering a striking contrast to the surrounding green landscapes.

The park is characterized by its diverse geological formations, primarily composed of clay, gypsum, and sandstone. The erosive forces of wind and water have sculpted these materials into a variety of distinctive shapes, including:

• Cabezos: These are isolated, flat-topped hills capped with harder layers of rock, protecting the softer material beneath.
• Barrancos: Deep ravines and canyons carved by water erosion, creating dramatic valleys and gullies.
• Bardena Blanca: The central plateau of the park, characterized by lighter-colored soils and featuring iconic formations like the Castildetierra, a striking pyramidal hill.
• Bardena Negra: The northern part of the park, with darker soils and denser vegetation.

The Bardenas Reales offers several marked trails for visitors to explore the park’s diverse landscapes. These trails cater to different modes of transportation, including hiking, cycling, and driving. Some popular trails include:

• Ruta de la Bardena Blanca: This route explores the central plateau, passing by iconic formations like the Castildetierra and offering panoramic views of the surrounding landscape.
• Ruta de las Barranqueras: This trail explores the network of canyons and ravines in the eastern part of the park.
• Perimeter Route: This longer route circles the entire park, offering a comprehensive overview of its diverse landscapes.

Access is generally permitted throughout the year, but certain areas may be restricted during specific times for conservation purposes or military exercises. It is advisable to consult the official park website or visitor center for updated information on access, trail conditions, and regulations before visiting. The park can be explored by car, bicycle, or on foot, allowing visitors to experience the unique beauty of this semi-desert landscape.
