From Oloron-Sainte-Marie or Pau, take the N134. Then head towards Laruns. After Arudy, take the D294 to the Chapel of Houndas.
Start from the bend above the chapel.
(S/E) Follow the track heading north-north-east. Continue to the Los Corraus fork.
(1) From the Los Corraus sign, turn left towards the south-west Cromlechs de Lou Couraus. Leave this path 150 m before reaching the Cromlechs.
(2) Follow theGRP® Tour de la Vallée d'Ossau. This path is well marked and heads north-west to the next intersection.
(3) Leave theGRP® on your right and continue west to the Col de la Hount Barrade.
(4) On your right is Bersaout (altitude 1,368 m) and on your left is Soum de Counée (altitude 1,361 m). Continue west along one of the paths leading down to the Cabane de Castillou.
(5) Pass to the left of the hut and descend to rejoin the track. Leave it immediately to climb up, cutting across the hairpin bends. Pass to the right of the Cabanes de Garrietche huts. Rejoin the track at a three-way junction.
(6) Go straight ahead and cut across three hairpin bends in succession to rejoin the track.
(7) Continue along the track for 1.5 km.
(8) Leave the track and continue across the pastures on the ridge to quickly reach the path that climbs to Pic d'Escurets.
(9) After enjoying the view, descend via the same route for about 400 m. Do not rejoin the track taken on the way up, but continue south (marked by stakes). At the entrance to the wooded area, join a track that leads to the Col de Marie Blanque.
(10) Take a grassy path heading north-east. It becomes a trail that quickly veers east then south-east. Descend a small valley to the Plateau de la Técouère.
(11) Find a track that runs alongside the Plateau du Benou (Plateau de Roland on the map) with magnificent hedgerows on its right. Follow it to the Col du Porteigt.
(12) Turn right onto a path that runs alongside the road and leads back to the chapel (S/E).
