The difference between this route and route 1 is the substitution of the Entzia area for the Améscoa. After 2 km along the NA-718 road, we turn right towards the Korostian area, a beautiful area of meadows and beech trees that we cross on good paths that lead us to the Monte Limitaciones race. At this point we head towards Larraona, passing by the Cueva de los Cristinos and the Artea Forest.
After a quick descent on concrete, we reach Larraona and start the passage through the Améscoa, alternating road, path and even some nice trails. Zudaire marks the end of the passage through the valley and the asphalt ascent to Urbasa, which will have as a reward the views from the Balcón de Ubaba. From here, we face the last part of the route through more stony tracks until we reach the asphalt road to Otsoportillo.
