Plazaola Nature - Rail Trail

The Larraun and Leitzaran valleys are a true nature sanctuary, dotted with farmhouses. In amidst their leafy slopes of beech and oak trees, a small narrow-gauge railway, “El Plazaola”, used to meander tirelessly between Pamplona and San Sebastián from the early to the mid-20th century.

Its path has now been converted into a rail trail which connects Pamplona and Andoain (Gipuzkoa), and runs through a spectacular landscap e of
steady slopes and an abundance of tunnels. Among them, the one in Uitzi, which, at 2.7 km, is the longest tunnel on any rail trail in Europe. Although
the tunnel is lit, it is a good idea to use headlamps to go through it.

Along the way, you will come across several renovated railway stations with services for cyclists in places well worth visiting, such as Latasa, Lekunberri or Leitza.
