The starting point for this hike is located in the car park in front of the Elizalde restaurant. To get there, see the "Practical information" section.
(S/E) From the car park, take the smallest stone path in front of you, which leads to the large pylon. This is theGR®10. The climb at the start is a little steep.
(1) This is the starting point of the circular loop. Leave the wide path and turn left. A little further on, leave the path again and head to the right. Then, at the top of the hill, you will pass the R10 boundary marker. You will then arrive at the summit of Manddale (or Manttale), marked by a triangulation point and the R9 boundary marker.
(2) You are now at an altitude of 574 m. This is also a historic site with traces of the Redoute de la Baïonnette. Continue straight ahead, but this time downhill. You will come to a large cairn.
(3) We will then continue straight ahead, making a round trip to climb Zigorriaga (549 m), where boundary marker R8 is located. On the way down from Zigorriaga, we will use the large cairn as a landmark.
(3) Once there, turn left onto a small path that will take you back to Bizkartzu on theGR®10.
(4) Follow it to the right towards the east to return to the starting point of the circular route a little further on.
(1) Then retrace your steps to return to the car park (S/E).
