From the Col de l'Aubisque, take the track that leaves behind the restaurant next to the stele. Follow it until it goes around the Soum de Grum from the east. Stay on the track at the intersection with the route of La Pastorale (n°19) and go down, through a few bends, as far as the Gros hut. Leave the track in the bend above the hut, passing between the hut and a drinking trough, and reach the Col d'Andreyt by a long level crossing on the grassy slopes. From the pass, follow the ridge to its highest point and descend to the Noulatte pass, at the foot of Soum de Grum. It is possible to make this summit in a short round trip. From the Col de Noulatte, return quietly to the Col d'Aubisque by a path due south.
Through our practice, it is essential to respect the work of the farmers, other operators and owners who welcome us on their land :
So that the herds do not escape, close all the electric fences well and do not damage them!
Also, do not disturb the herds, greet the people you meet with a friendly "hello", and of course bring back all your rubbish! Do not cut routes through the meadows, and do not picnic either!
