The extensive territory of the Sierra de la Culebra rises in the north-eastern region of the province of Zamora, surrounded by the counties of Aliste, la Carballeda, Sanabria, Tierra de Campos and the Portuguese county, Tras Os Montes.

This gentle and modest hill landscape - the highest point is 1,243 metres, the summit of Peña Mira - is the result of erosion of the ancient materials comprising pleated outcrops of slate, granite, quartzite and gneiss from the Ordovicic period.

The primitive oak and holm oak woods have been substituted by artificial plantations of conifers and extensive areas of heather and rockrose. This region provides home to the largest population of wolves in Western Europe.

Enviromental Areas

One of the largest populations of wolves in all Europe. Deer, roe deer, and otters.
Ordovicic outcrops formed by a collection of narrow pleats that have suffered different levels of erosion, giving rise to an Appalachian type of relief.
Planted pine trees.
