Las Merindades is a large region located in the north of the province of Burgos, considered one of the areas with the greatest natural, historical, and scenic richness in Castile and León. Its valleys, mountains, forests, and medieval villages make it an ideal destination for those seeking nature and heritage away from the most crowded routes.

The region is home to some of the most beautiful towns in the province, such as Frías , considered one of the smallest cities in Spain, Medina de Pomar , Espinosa de los Monteros , and Oña . Castles, monasteries, medieval bridges, and Romanesque churches form part of a valuable historical legacy that reflects the importance of the territory during the Middle Ages.

Among its main natural attractions are the Ojo Guareña Natural Monument , one of the largest karst complexes in Europe, the spectacular Salto del Nervión , the highest waterfall in the Iberian Peninsula, and numerous gorges, hiking trails and viewpoints scattered throughout the region.
