The new cable car system from Courmayeur, Italy to Pointe Helbronner is now open. You can again visit Italy by cable-car over the glaciers from Augille du Midi. The cabins rotate like a revolving restaurant.
Buses no longer stop at the Chamonix railway station; instead, they go to a new station in Chamonix Sud on Avenue de Courmeyeur (by the bowling alley). See http://www.chamonet.com/news/new-bus-and-coach-terminus-in-chamonix-sud-chamonix-main-town-685550.
Thanks, Robert!
