Limestone gullies with soaring rock faces, the river running below, the air cut by the wings of griffon vultures and the echo of the clattering of the railway line. This is the "Irati" as it passes through the Foz (gorge) at Lumbier, a Nature Reserve
The Irati was the electric passenger train in Spain, which led it to appear in several articles in the newspapers and encyclopaedias of the time. From 1911 to 1955 the train covered the 58 kilometres
along the Pamplona
At present, 6 kilometres of the route have been arranged as a greenway, allowing visitors to travel it at their leisure.
