In this space are the most extensive and best preserved junipers on the entire planet. Some of the Arlanza junipers are over two thousand years old.

The La Yecla gorge is a deep and narrow gorge carved out of the thick limestone banks that characterize the relief of the Peñas de Cervera and can be walked on a series of walkways. The rocky relief of the area has favored the development of an abundant population of birds of prey. In a few kilometers the ruins of the monastery of San Pedro de Arlanza, the town of Covarrubias and the monastery of Santo Domingo de Silos are located.
