At the top of the Col de Couraduque, park in the highest car park, near the station building.
(S/E) Walk past the building and take the right-hand track opposite, which descends slightly through the forest.
The trail is very well marked "Refuge du Haugarou".
The trail descends just 60 metres over nearly 2 km.
(1) Cross the Abèdet. This is a heavily wooded area except around Bourassouse, where a large flat area has been cleared (marked as wooded on the map and on Géoportail).
Then the trail begins a winding descent.
(2) Pass the Ruisseau de Taillade ravine, then the Ruisseau du Bergon ravine, descending from the Col de Bazès and joining theGRP® (Grande Randonnée de Pays) of the Tour du Val d'Azun.
(3) This trail finally arrives at the bottom of the valley at 1,210 m at the Refuge du Haugarou.
(4) The return journey follows the same route back to (S/E).
