In this route we go back to Tierra Estella but in this case we will go around the Sierra de Andía. First we must overcome the Lizarraga Pass that leads us to this region of Navarre.
After passing very close to the Alloz reservoir, we face the second climb of the route, the Puerto de Guembe. In this case almost 6 km at 5.5% that bring us closer to the Ollo Valley, which we will quickly overcome towards Iruntzun. From here we return to the campsite, but before we finish, the climb to La Cadena awaits us as the finishing touch.
If you do not feel strong enough for this last effort, in Arbizu you can take the road directly to the campsite.
