Let it snow at the show

Heralding the beginning of the annual exodus to the mountains, this show has 300 tonnes of the real thing.

Snowboarders and skiers can show off their backflips and spins in the Big Air competition, which this year features a death-defying hip jump (90-degree turn).

There's expert advice about safety, working in the Alps and other essentials in the Extreme Sports zone. Free lessons are on offer (book on arrival) or you can enjoy apres-ski 'speed flirt' sessions at Brewski's Bar.
