Discover the secrets that this small natural area holds within the Roncal valley. The Belabarce river runs through the valley, irrigating the fields for grazing, potatoes and pasture. In addition, the valley has an important Scots pine and beech-fir forest reserve. Some of the most extraordinary places in the valley are the Cueva del Ibón (Lake cave) and the Cascada de Belabarce, a beautiful icy waterfall where the most daring can bathe.
Access: Walk to the Belabarce waterfall along a route that begins in the town of Isaba.
