Points of interest

The Hoces del Alto Ebro y Rudrón natural park is located in the northwest of the province of Burgos and presents a landscape of great beauty. Narrow valley bottoms wedged between steep gorges and cliffs are crossed by the Ebro and Rudrón rivers. These are in contrast to the extensive, almost flat moorlands located at higher altitudes.

Hoces del Alto Ebro and Rudrón natural park

The Ebro River crosses the north of the province of Burgos from Orbaneja del Castillo to beyond Miranda de Ebro for 150 km in a succession of canyons (hoces) alternating with open valleys, as well as other natural elements in the surroundings that constitute an area of natural interest. The route of the river goes from west to east, but very sinuous, either because it ends up crossing a mountain massif in the most favorable place (dissolution of limestone rocks mainly) or because it forms meanders in the valleys.

The Las Loras UNESCO Global Geopark

The nearby Las loras UNESCO Global Geopark is halfway between the Castilian Plateau and the Cantabrian Mountain Range. This transitional location gives the region the typical weather and environmental features of the surrounding regions. It also possesses a wide range of environments and biodiversity, with both Euro-Siberian sites as well as Mediterranean sites. In addition, the unusual topography resulted in a peculiar landscape where limestone cliffs and significant high altitude moorlands alternate with gorges and deep valleys created by the river system.
