First section of Via Verde de Plazuela. We leave Pamplona suburbs. First part on a new road, a very quiet conventional circuit, at some point we will have to be careful because we cross some road although with little traffic, the average route passes through a road parallel to the old national road where we go through a tunnel that is shared with vehicles, regulated by traffic lights, to cross two imposing rock formations known as The Two Sisters, while we border both sides of the river. The route gains as we advance, gaining splendor in the last 5-8 km. where it fully follows the old train path, surrounded by vegetation, for about 3 km. Before reaching Lekunberri, a waterfall and springs that come down from the mountain stand out. Easy circuit, although at some points there are some slopes that we then have to go down.

Navarrese town located in the Larraun valley. Historically it has been a border place, and its own name, which means "new site", indicates that it was destroyed and rebuilt in 1430. It originally consisted of a palace and a defensive tower. It was also important for its customs activity already in the 12th century, since taxes were collected here from merchants who entered the Kingdom of Navarre. The Ayestaran hotel, opened in 1912, is one of the most emblematic businesses and buildings in the town, since famous people such as Ernest Hemingway, Orson Welles and Alcalá Zamora have stayed in its rooms.
