Unlike so many tips that are tied into a particular hotel, lodge etc.. the Koh Chang Sun is the local paper and won't try to sell you anything. Just a good list of all the things to do on the island, maps and recommendations!
Videos and pictures from in and around Chamonix with a great movie of the glaciers and a charity ascent of Mont Blanc.
A fine website with 100 or so 5-10 min video clips/narratives on Chamonix & Mont Blanc Massif - follow 'Rubriques/Topos' to get there & enjoy it (they all talk French though)!
