Rivers basin of Isuala: Canyons and tributaries of Balces

The river Isuala offers the longest and most continuous canyon of the zone. It arises in 1.290 m from height in the Port of Serrablo and comes down, passing near Las Almunias, to throw itself near Bierge into the river Alcanadre where was installed via – ferrata of Peñas Juntas. In term of canyons, we differentiate 3 sections called Balces (or Balced) : the longest is upper Balces, followed by the most known Oscuros del balces and the final part where the limestone is transformed concloméré, called Estrechos del Balces. This pond of Isuala offers the biggest concentration of canyons of the Sierra of Guara with its multiple, mainly dry tributaries but a big interest in terms of landscapes, as well as to the technical level for the amateurs.
