From Lourdios-Ichère, head up the D341 road alongside the Gave d’Issaux. Park near the suspension bridge (elevation 614) in a lay-by on the right-hand side of the D341.
(S/E) Cross this bridge, keeping to the left bank of the Gave d’Issaux, and follow the path that winds through the forest.
(1) The path is not marked on IGN maps but is perfectly passable through the forest. Follow it, cross the small Ruisseau d’Arriou de la Sèque at elevation 623 and continue straight on.
(2) At the junction, turn right, heading due south. Carry on straight ahead. The path turns into a forest track. You’ll pass a superb chalet on your right. Carry on straight ahead. Cross another small stream whilst staying on the same track. You’ll come to a fork in the track.
(3) You’ll see the road. Don’t join it. Turn right into the woods (the path is a bit overgrown but is still passable). Follow the road via the path that winds through the woods.
(4) The path takes you back to the D341 road between two magnificent trees. Take the road by turning right. Cross the Gave d’Issaux via the Pont du Gouat. Stay on this small road until you reach your car (S/E).
