At the « Lapurdi » sign (315m), leave the tarmac road to climb the dirt track to the right, marked in red and white. When the path bumps against a gate, go up the very steep grassy path on the right along the fence, then in the ferns. Reach a grassy pass (385m), with a view of the Ibardin pass on the right and the Rhune on the left (the first path on the left allows a round trip to the Redoute des Emigrés). Continue 30m to an intersection of 5 paths: take the second path on the left, downhill (Biarritz in view). Go through an esplanade (quarrymen’s quay) and then, after the collapsed dolmen, continue downhill into the forest. At the bottom, after the barrier, take the left-hand path until you return to the starting point.
