the easiest way is a combo of bus/train, but I would take the shuttle, google it. its worth a few extra euros. but I believe chamonix.com or something close to that has alot on this. Chere Coulior is a classic as is Frendo Spur, CM (sp)on left side of north face triangle on du tacul. South Ridge Aig. de la perserience (sp) just a few. There is a office to get condtion reports across the street from the tourisom office. walk by the guides office and head up stairs. Have fun!
