At the Pitare pass (316m), leave the GR markers to turn right onto a path that immediately splits into two branches: choose the one on the left that enters the forest. The path goes down the wood in two large bends and then runs alongside a stream. Once you reach a dirt track (221m), cross the stream and follow the track to the right. At the Lantzeraerreka crossroads (200m), follow the second track to the right. After 200m (Y-shaped intersection), be sure to leave the track and take the path on the left, through a tunnel of vegetation. At the end of a bend in the road, keep to the left downhill, then 80m further down to the right.
