Thanks! Already done.
If you take the train from Geneva to Chamonix, beware that the Geneva train station is *not* the central station. You need to cross half the city to get to a small (grass overgrown) station from where the train to Chamonix departs. At least, this was the situation 3 years ago.
This extra time you need to get from one station to another caused me to miss the last train of the day *twice* (on the way to Chamonix, and on the way back). Missed it by mere minutes both times, while I ran the traject with 15 kgs on my back. I can ensure you, I wasn't very happy. I spent the next year cursing swiss trains... Had to stay in a hotel in Geneva.
Maybe you can make it when you take the bus, but I didn't have swiss money.
Thanks RBI, your info has been included in the "Getting There" section.
Its an easy train ride to Chamonix since there are direct trains from Paris, Geneva, and several major cities. There is a station in central Chamonix and everything is within easy walking distanced.
Your starting point for most climbs will be cable cars and/or the Montenvers mountain train. Public transportation is practical in the Chamonix Valley. If you have a car, it is quite difficult to park downtown due to tourists.
