The Chistau Valley

Landscape and climate

The Chistau Valley is formed by the natural catchment area of the Cinqueta River (tributary of the Cinca River in Salinas de Sin), bounded on the north by the Pyrenean border mountain range, with the French Aure Valley and on the east by the Benasque Valley . The most representative peaks inside the valley are Posets or Lardana (3,369 m, second summit in height of the Pyrenees), Lierga massif (2,268 m), peak of the Pegueras (2,643 m), Punta Suelza (2,972 m), Punta Fuesa ( 2,858 m) and Culfreda (3,043 m). The climate of the valley is typical of mountain, with very cold winters, springs practically nonexistent, short summers and temperate autumns.

Fauna and Flora

The forests abound, of wild pine and caixigo (cajigo) in low areas and of black pine in the highest ones, although the territory is rich in natural meadows where different flowers abound: chicoina (dandelion), margalida (margarita), gallazo or bushes (purple lily), chonzana (gentian), camamila (chamomile), ababol (poppy), ...

The onso (bear), the wolf and the deer have long existed only in the memory of the oldest, but you can still find "solecos", "chizardos" or "sarrios" (names to refer to the chamois), ptarmigan nival (Lagopus muta), birds of prey such as vultures, aligas (eagles), esparvés (kites), quebrantahuesos (lammergeiers), nocturnal birds such as bubons (owls) or babiecas (owls), wild cats, fuinas (martens), rabosas (foxes), liebres, perdigachos (partridges), zapos (toads) and ixingadanas (lizards), among others of smaller size, such as boletas (butterflies), pantinganas (flying deers) and cuquetas de luz or lucetas de San Juan (fireflies).



On the summits there are abundant granites with sharp shapes and areas of blackish slates. In the area of the Sierra de Cotiella, the limestone that forms makes the water disappear by its abundant chasms and caves and that the rock crumbles little by little. Throughout history, mines of silver, lead, iron and, above all, cobalt have been mined, as well as salt and good materials for construction.

Natural heritage

The Bal de Chistau is part of two protected natural mountain areas: the Ordesa y Monte Perdido National Park and the Posets Maladeta Natural Park.
