Pallars Sobirà (, ) is a
comarca (comparable to a
county or
shire in much of the English-speaking world) in the mountainous northwest of
Catalonia, Spain. The name means "Upper
Pallars", distinguishing it from the more populous (and less mountainous)
Pallars Jussà to its southwest. Its capital and largest municipality is
Sort. Located in the central
Pyrenees, Pallars Sobirà stretches from south to north, starting at the gorge of Collegats to the village of Alós d'Isil, following the course of the river
Noguera Pallaresa. It is the fourth biggest comarca in Catalonia in terms of surface area, and has one of the lowest densities of population in the country, about 5.1 inhabitants per km². All together, it has approximately 7,000 inhabitants.
