A route designed for the most prepared people where we will face 4 mountain passes evenly distributed along the route. After a first part of the climb, we face the first climb would be, El Perdón, in this case on the side of Uterga, something more entertaining than the general road. After reaching the summit, we continue again along the back roads of the Pamplona basin until we face the hardest pass of the route, Etxauri.
We start the descent and the Muniaín road, recently upgraded to Azanza, allows us to access the Ollo Valley to climb a third pass, the one of Goñi, much steeper than Etxauri. Once we crowned and after a rapid descent, the last difficulty of entity of the route arrives, the Puerto de Lezaun.
