Have skiied and stayed in La Clusaz on numerous occasions. It is a traditional and pretty small french Village. Frequented mainly by the French, English isnt widely spoken (which all adds to the experience).
There are a selection of nice restaurants and small bars. More of a relaxed atmosphere than a full on apres-ski experience! The skiing is linked over a serious of varying mountains. Being a mainly red-runner there is lots to choose from. The views of MtBlanc from the top of the Balme area is a great photo opportunity. The runs down from L'Etale are also enjoyable. There is a nice green/blue domain on the Beauregard ideal for beginners. Being a low area snow can sometimes be thin on the lower runs but every year the snow making gets better and better. The area is v close and linked by bus to Grand Bornand which opens up another varied ski area if you fancy a change. Being approx one hour from Geneva it is easily accessable. As an option it is also an easy 8hr drive from Calais if coming from the UK. Overall its a great destination, ideal for varied groups and families (ESF ski schools recommended). Give it a try....you will enjoy!
