Please note that there are no water sources between Le Saquet and the Refuge de Rulhe! Take a good supply with you. In the second part, water sources are very limited (only at some huts, and not all of them).
The Lièvre Blanc chairlift in Ax 3 Domaines, which climbs to 2,000 metres, only operates in summer (July-August) and on the first weekend of September for the summer season.
Avoid this hike in poor visibility.
The main difficulties are aerial passages on certain ridges and numerous scree slopes.
