Foz de Lumbier Strict Nature Reserve

It is one of the most spectacular gorges in the Navarre region, in northern Spain and can be easily explored on foot thanks to two marked trails.
Foz de Lumbier is a small, narrow gorge measuring 1,300 metres in length, with vertical walls reaching a maximum height of 150 metres. Large birds of prey live in its crevices, cracks and ledges, among which griffon vultures are abundant. They also serve as a refuge for foxes, wild boars, badgers and Egyptian vultures. As for the flora, there are abundant shrubs such as thyme and groves of poplars, willows and ash trees.Unlike many other gorges, the Lumbier gorge can be traversed via two simple paths at the foot of the cliffs. These are signposted but pass through two tunnels that lack artificial light.

Environmental information
A small 6-kilometre long greenway, the Irati Railway trail, leaves the town of Lumbier and ends in the town of Liédena, bordering the Irati River and partially crossing the canyon. Very close by, about a 10-minute drive from Lumbier, is the even larger and wilder Arbaiun Gorge, with cliffs up to 400 metres high. This work of nature by the Salazar River can be explored on foot along a path from the town of Usún or admired from above using the vertiginous Iso viewpoint, on the side of the NA-178.
