Biescas in the context of "Gállego (river)"

Alto Gállego (Aragonese: Alto Galligo) is a comarca located in the north of the autonomous community of Aragón, Spain. It occupies practically the entirety of the upper basin of the Río Gállego.

Historically the comarca was a part of the area known as Jacetania, the original nucleus of the old county of Aragón. The historical territories integrated into that area were the Tena Valley, the lands surrounding Biescas, and the Serrablo.

The Col du Pourtalet, El Portalet or Portalet d'Aneu is a mountain pass and border crossing in the Pyrenees, between France and Spain. The pass reaches an elevation of 1,794 m (5,886 ft), and links the Ossau and Tena valleys.

The road across the pass is known as the A-136 on the Spanish side, and links to Biescas and Huesca. On the French side the D934 road connects the pass to the towns of Laruns, Oloron-Sainte-Marie and Pau. The pass is kept open in the winter, but in case of heavy snowfall may be closed for a couple of days. Due to the Schengen Agreement, the checkpoint is not currently functional.
