The Plazaola Green Route has reclaimed several kilometres of the railway line used by the first train to connect Pamplona with San Sebastian, which ran between 1914 and 1953. The local Tourist Information Office is to be found in the renovated station of Lekunberri, a town situated 34 kilometres north of Pamplona. From the station, now that the 2,680-metre-long tunnel at Uitzi has been reformed, you can make the 42-kilometre trip from Lekunberri to Andoain (Gipuzkoa) without any interruptions, via Leitza and its 14 small tunnels (also reformed).Leitzalarrea is very close by, an exceptional forest with 37 distinct species of trees.
