Introduction to the Sierra de Culebra

The Sierra de la Culebra is a Spanish mountain range located in the northwest of the province of Zamora and the autonomous community of Castilla y León. It’s main value lies in the large population of Iberian wolf with the highest concentration in Spain. Populations of red deer, roe deer and wild boar are also very significant.

The name of this mountain range is thought to have been inspired by its undulating contours, which bear a resemblance to a snake, hence its name “Sierra de Culebra” (Snake Mountain Range). However, another theory suggests that the name could have stemmed from the historical presence of snake species, including the smooth snake, the horn-nosed viper, and the whip snake.

The area continues across the border and is included in the Portuguese Natural Park of Montesinhos. Its small elevations range from 800 to 1,200 meters in height. Reforestation pine is dominant in the mountains, although native forest masses of oak, Spanish oak, and chestnut are also present. In the scrublands, heather and rockrose are the dominant plants.

The area has also become famous as a starlight destination. The Starlight Foundation is a non-profit organization that was founded in 2009 to promote the protection of the night sky and the development of “astrotourism” and there is an ever growing list of starlight destinations in Spain to visit.

The Sierra de Culebra: A land of wolves.

This mountain range is internationally renowned for being home to one of the most precious faunal treasures and a symbol of conservation efforts—the Iberian wolf. Its vast expanse allows for days of exploration through wide, untouched natural spaces, far from human presence. It stands as one of the premier destinations in Spain for wolf observation.
