The Sierra de la Culebra, or Serra da Coroa (in Portuguese), is a mountain range in Castile and León, northwest Spain, and northeastern Portugal. It lies 7 km south of Puebla de Sanabria in the comarcas of Aliste, Sanabria and La Carballeda (Zamora Province), as well as Vinhais and Bragança municipalities in the District of Bragança. Its highest point is 1,243 metres (4,078 ft) high Peña Mira, located near Flechas, within Figueruela de Arriba municipal term; other important peaks are Miño Cuevo 1,211 metres (3,973 ft) and La Pedrizona 1,054 metres (3,458 ft).[1]
The Sierra de la Culebra is a 95 km long regular mountain chain of medium height, forming a natural border with the Portuguese region of Tras os Montes on its western end. Its slopes are wooded, occasionally ravaged by forest fires. The summits of the range are often covered with snow in the winter and there are odd-looking rocky quartzite outcrops on them.
Among the rivers in Spain and Portugal having their source in Sierra de la Culebra, the Castro River, Tera, Tuella, Sabor and Maçãs (Manzanas), deserve mention.
These mountains are famous as one of the few remaining strongholds of the Iberian wolf.[2]
