In Laruns, take the D934 road towards the Col du Pourtalet. Pass Lac de Fabrège. Continue for 9 km to the Cabane de l'Araille, 1.2 km from the Spanish border. Park in the car park at the side of the road.
(S/E) Cross the road and take the track between the road and the Gave de Broussey. This marked path leads to the Refuge de la Pombie, the starting point for climbing the Pic du Midi d'Ossau. Cross a footbridge.
(1) Leave the path to the refuge on your right and continue along the track that turns left. It passes to the right of a pastoral centre.
(2) Enter a small valley that opens onto a vast plateau, the Plaa de la Gradillère.
(3) The path passes to the right of a more or less dry pond and climbs about 200 metres to reach the Col de Houer.
(4) Descend due west to reach the Lacs d'Houer lakes.
(5) After enjoying the site, return via the same route to the car park (S/E).
