A lesser known climb in the lake region of the Pyrennes; after a gentle ride up from Saint-Lary-Soulan, the climb begins. Ascend to over 2,100 metres/6,800 feet to the largest reservoir in the Pyrennes, criss-crossing the creek on your way to the switchbacks of Lacets des Écureuils and then the steeper Lacets des Myrtilles and Edelweiss. Despite the clouds, there is fantastic roadside scenery along the way.
