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.

Perhaps one of the most attractive sections of the Vía Verde del Plazaola since we went through several tunnels, including the longest with a length of 3700 m. Although it is illuminated, I recommend you take your own light or flashlight in case there is a section that does not work in the luminary.

The Bartolo tunnel of the Plazaola natural path is 235 meters long. It is advisable to use your own lighting, in case the tunnel lighting does not turn on. In recent months it has been under construction due to the danger of landslides, so an alternative with a greater gradient must be taken.
