From Navarre to Gipuzkoa through the most unspoiled areas of Leitzaran

The Larraun and Leitzaran valleys are a veritable natural sanctuary dotted with country houses. Between their leafy hillsides of beech and oak, a small narrow gauge railway “La Plazaola” used to snake tirelessly between Pamplona and San Sebastián-Donostia until the mid-20th century. Today its spectacular route features rehabilitated stations and numerous tunnels, among which is the Uitzi Tunnel, at 2.7 km the longest tunnel on all the greenways in Europe. In addition, the extention to Pamplona and its conection with the Bidasoa Greenway makes it an essential greenway.
