The car park is near Urcuray church on the street perpendicular to the D10.
(S/E) Follow the road south-east. At the first intersection, turn left along the stream until the road leaves the stream and starts to climb.
(1) Leave the road to go through a metal gate on the right and follow a path that runs alongside the stream. After passing a ruin, continue along the path that climbs up into the valley.
In the forest, at the fork, take the path on the right.
Above a waterfall, a trail takes over.
After a gate, it continues to climb to the left or right of the stream, crossing a few muddy sections (water catchments) until it reaches an intersection in the middle of several water pipes.
(2) Ignore the paths to the left (ford) and right, and continue straight ahead on the path along the river. The forest gradually thins out. Continue to an electricity pylon with a Y-junction.
(3) Take the grassy path opposite to finish climbing up the valley on a wide path that winds under the power line to the Col d'Iramalda.
(4) Ignore the road and take the path on the left. After 50 metres, at the barn, turn left again onto a wide dirt track that climbs up the western flank of Ursuya. Pass under a beautiful barn and reach a flat section (Pilotaxilo). Continue along the fence and follow the only path that descends towards a valley.
Ignore a path coming from the left, pass the spring and climb gently up to an intersection near a barn.
(5) Descend opposite for 50 m, around a bend, then turn left, west, onto a path marked "Retour Cambo". With a beautiful view of the Hasparren neighbourhoods, it goes around a dome. When the path opens onto a fern-covered meadow, keep to the rightmost track to descend steeply towards a grassy plateau. Climb back up briefly through the gorse, then reach a T-junction: continue right on the wide path. At the four Basque houses, turn right for 20 m.
(6) Turn left onto the road that descends to the Gillamuren farm.
Turn right in front of the shed to descend a grassy path to a Y-junction near a ruin.
(7) Take the path on the left to rejoin a tarmac road that descends to the road you took on the way there.
(1) Return along the same route you took on the way there to the car park (S/E).
