From the refuge of Baysselance, the path descends to the Ossoue dam and coincides with the most frequented route for climbing the Vignemale.

From the Ossoue dam, a path runs along a semi-sloping slope of grassy terrain that passes by the Lourdes cabin and the Sausse-Dessus shelter. If the weather is good, if not, it would be better to consider an alternative to Gavarnie; we head towards the des Ligades peak, where we will take the ridge that starts just south of it and leads us to the Pico de San Andrés.

From here we descend the ridge to the Des Especieres pass and then to the Bujaruelo pass. From here we take a nearly horizontal path that is very frequented in summer and passes under the Taillón rock. We must be careful not to slip on this path, as it is exposed and the crevasses are persistent all year round.

Finally, the Sarradets pass is overcome and you reach the refuge.
