Mind the traffic at the Alto, which comes faster than expected.
You will arrive at the Alto at a large and fairly dangerous highway crossing. The way ahead is marked, and you are heading towards the signs marked Larrabetzu. After crossing the highway, turn left at the first junction, uphill. You will pass the small Ermita de San Esteban and return to a woodland setting. The next place with a name is Eskerika, but you would not recognize it for much more than a single building.
