This is one of the final foothills of the Cantabrian Mountains. Montes Obarenes Nature Park, in the province of Burgos, forms a magnificent natural wall sheltering La Bureba.

Bounded by the River Ebro, it boasts a wealth of treasures including the mountain ranges of Oña, la Llana, Pancorbo, Arcena and the Obarenes mountains themselves, which rise up to a maximum height of 1,237 metres at Pan Perdido. The landscape is scattered with stunning natural features, including steep passes, gorges carved out of the rock by the rivers Ebro and Oca as well as the ravine formed by the Purón in the Arcena mountain range.

The wealth of trees is the result of its prime location between the Atlantic and Mediterranean biogeographic regions. The entire area is scattered with precipices where birds of prey such as the griffon vulture, Egyptian vulture, golden eagle and goshawk nest. The magnificent landscape forms a backdrop for countless cultural treasures, as it is dotted with towns that are rich in history, such as Frías, which will take visitors back in time.
