Cordillera Oriental, Colombia in the context of Sierra Nevada del Cocuy

The Serranía del Perijá, Cordillera de Perijá or Sierra de Perijá [pe.ɾi.ˈxa] is a mountain range, an extension of the eastern Andean branch (Cordillera Oriental), in northern South America, between Colombia and Venezuela, ending farther north in the Guajira Desert, a distance of about 310 kilometres (190 mi). It separates the Maracaibo Basin from the Cesar-Ranchería Basin. Some of the area has been considered as a Flora and Fauna Sanctuary.

Boyacá (Spanish pronunciation: [boʝaˈka]) is one of the thirty-two departments of Colombia, and the remnant of Boyacá State, one of the original nine states of the "United States of Colombia".

Boyacá is centrally located within Colombia, almost entirely within the mountains of the Eastern Cordillera to the border with Venezuela, although the western end of the department extends to the Magdalena River at the town of Puerto Boyacá. Boyacá borders to the north with the Department of Santander, to the northeast with the Bolivarian Republic of Venezuela and Norte de Santander, to the east with the departments of Arauca and Casanare. To the south, Boyacá borders the department of Cundinamarca and to the west with the Department of Antioquia covering a total area of 23,189 square kilometres (8,953 sq mi). The capital of Boyacá is the city of Tunja.
