How much luxury is enough?
In the world of top-notch ski chalets, five-star opulence is just the starting point.
Bespoke, boutique and beautiful are the bottom line, plus the best materials, award-winning design and so many toys and extras that the slopes outside are in danger of becoming an afterthought.
The service, too, must be beyond impeccable; these ski resorts are places where nothing is too much trouble.
Here are nine of the best mountain masterpieces in the Alps.

Chalet Zermatt Peak, Zermatt (Switzerland)
There's the standard, run-of-the mill luxury -- and then there's Chalet Zermatt Peak.

This is the stuff of the movies -- the entrance tunnel hewn into the rock is reminiscent of a Bond villain's lair. A floating walnut, steel and glass staircase and a lift access five more levels of Swiss swank.
There are five lavish bedroom suites, while the master has its own Jacuzzi and the top-floor gallery bedroom has a glass roof to take in the peaks and the stars from bed.
An indoor/outdoor Jacuzzi is the centerpiece of the indulgent spa area.From about $53,000 Swiss Franc to $178,000 for a week with Alpine Guru.
