Chamonix is probably the most convenient winter sports resort to get to for a weekend break from most of Europe and the easiest day trip from Geneva. It is a fabulous resort, but the skiing and snowboarding are not as good as you might expect. The first issue is that most of the slopes are a bus ride away from all the hotels and the ski bus service, whilst good, is far from perfect. The second issue is that the skiing on piste is generally good but unexceptional, with the single exception of the 20km off-piste run down the Vallée Blanche off Aiguille du Midi - possibly the best run in the entire Alps but one where a guide is absolutely recommended and where several people lose their lives every year. It is not difficult and a competent intermediate could attempt it, but the walk from the top station and the crevasses on the glacier are extremely dangerous.
The nightlife in Chamonix is excellent, possibly the best of all the French resorts. Despite my reservations about the skiing - which is very good but not as good as you might expect - and the relatively narrow range of winter sports you can pursue, this is one of my favourite winter sports resorts in the world. It was chosen for the very first Winter Olympics back in 1924.
