Refuge has a year-round manager
The Chistau valley is in north-east of the district of Sobrarbe, surrounded by high mountains, covered with thick forests and bathed by the waters of the river Zinquetar. Part of the valley falls within the terrain of the Posets-Maladeta Natural Park. The Viadós mountain hut is nestled at the bottom of the valley, at the foot of the majestic Posets-Llardana peak, the second highest in the Pyrenees. Surrounded by the traditional mountainside landscape, the Viadós offers visitors one of the most fabulous views over the Pyrenees.
