Authentic MTB route where we are going to get into one of the wildest and most beautiful areas of the area. After completing the hard ascent of Urra, we crest Larraiza enjoying spectacular views of the surroundings before facing the dizzying descent of the Puerto de Rulez that leads to the Valley of Allín. Attention to the initial part of this descent as it presents some complicated steps.
After a bit of calm in the form of road and flat terrain, we face the short but hard climb to Belastegi that is preceded by a beautiful descent where again there are some specific areas where we have to be fine tuned. Then, a calm stretch on asphalt before starting the ascent to Eraul through the precise regacho that bears the same name.
After crowning the climb to the height of the famous oak and enjoy the views, we face the final part of the route in which we will ascend again to Larraiza by a long and hard climb. Once we finish the ascent, we start the descent of the Puerto de Urra.
In the track we have put as an alternative a stretch of trail parallel to the uphill road, which is more fun than this one. As a final touch, we include the Artaza trails that complete the descent from Urra, although if time is short, we can take the section used on the way to get to the campsite earlier.
