San Glorio

San Glorio is a mountain pass in the Cantabrian Mountains of Northern Spain. The pass reaches an elevation of 1610 meters along the national highway N621 which connects the city of León with Cantabria and which passes through Asturias. The pass is situated some 800m from the southern border of the Picos de Europa National Park, a park included in UNESCO's World Network of Biosphere Reserves and shared by the provinces of León, Asturias and Cantabria. The valleys of this part of the Cantabrian Mountains include sites in the European Union's Natura 2000 network and Special Protection Areas for the conservation of wild birds. San Glorio is used as a corridor by the Cantabrian brown bear Ursus arctos, catalogued in Spain as being in danger of extinction. Moreover, the slopes of the glacial valleys making up the surrounding region are home to an important variety of plant life. ()
