On leaving Gèdre towards Gavarnie, turn left onto the road to Héas. Park in the large car park at the Chapelle d'Héas.
(S/E) Stay on the road until you reach a small car park where the path, marked by a yellow sign, begins.
(1) Take this path to the left; at the next junction, continue straight ahead, leaving the sign for the Cabane de l'Aguila on your left. Follow this well-marked path along a very gentle slope to reach the Touyères water intake. The Pyrenees National Park begins here.
(2) Continue along the path, keeping to the right bank of the stream, before reaching the large hairpin bends that end at the junction for the Cabane des Aires.
(3) Take the almost flat path on the right to discover the first two Lacs des Aires.
(4) Pass between these two lakes, then follow a very gentle climb to reach the other two. Go round them and walk gently along the flat before tackling the short climb through the mountain pasture leading to the Vierge de Troumouse.
(5) Head back down, veering slightly to the right, to reach the upper car park on the Route de Maillet (D922).
(6) From this car park, use the various paths that cut across the bends in the road to reach the car park at the Auberge de Maillet.
(7) Continue by taking the path on the right that cuts across the bends of the same road to reach the first crossroads after the toll hut.
(1) Retrace your steps along the route you took on the way there to return to the starting car park (S/E).
