France. Started Tour des Glaciers at Pralognan. Reached Refuge du Col de la Vanoise at noon. Left backpacks. Took small wrong path to the left. Dead end on a ridge. Went back and to the right. Saw path and big cairns. Climbed to massive glacier. Walked at the edge. Climbed on rocks. Saw a guy on the left. Ran to him and talked. There's a way to the top! Lost some time but it was worth it. What a view. Back down, ate a lot. Decided to keep going after. Saw chamois at Col de la Vanoise. Turned right at bunker. Sun setting. Passed by lakes. Stumbled in streams. With help of full moon light, we arrived at Refuge de l'Arpont at midnight. Not much space left in bivouac area.
