Had enough of the crowded trails at your usual ski resorts? Prefer pristine snow, challenging climbs and spine-tingling declines? Ready to stare insane vertical drops straight in the face and even risk the possibility of an avalanche?

Get to it, then. Wax those Rossignol backcountry skis, strap on your helmet and avalanche safety gear, and go off-piste.

Here are some locales across Europe and the U.S. worthy of the toughest winter adventurers.

Chamonix, France:


offers one of the most beautiful settings in the world for extreme skiing, as premier Alp peak Mont Blanc looms majestically over this small town of 10,000. Located in France's Haute-Savoie region, it was appropriately the home of the first Winter Olympics in 1924. During the summer, mountain bikers and climbers flock here to flex their muscles, but the name Chamonix has always remained synonymous with great winter sport.

Think about spending six days ski-mountaineering in the Mont Blanc range with the

Chamonix Experience

and guide Russell Brice, certified by the International Federation of Mountain Guides Association. Brice has ascended the highest mountain in Europe more than 85 times, and its rounded summit is accessible via backcountry skis. Stand atop the roof of Europe and take in your conquest, arms and poles raised to the sky. Of course, you'll also need to have skills with an ice ax and crampons to be able to get to the top.

Guide Yan Raulet, also IFMGA-certified, offers tours on both the French and Italian sides of the mountain, ranging from two to five days. Start by skiing off-piste from the lifts at Les Grands Montets, at 3,233 meters (10,606 feet). Then climb up to the Aiguille du Midi, famous for the


, which brings tourists up to a terrace at 3,842 meters, where on a clear day, you can take in breathtaking views of the Matterhorn, Monte Rosa and the Grand Combin.

When sufficiently rested, and the awe inspired by your surroundings has begun to abate, descend into the Le Refuge du Requin, "The Refuge of the Shark" in French, for a bit of repose. It's a hut tucked away along peaks appropriately resembling the dorsal fin of one of those menacing fish.

A caveat: Much of the Chamonix backcountry terrain is best skied by experts, as it is often quite steep, and avalanches are more prevalent here than in many other spots.

Riksgränsen, Sweden:

Located 130 miles north of the Arctic Circle,


in Sweden is one of the world's northernmost ski resorts. It's based in the Lapland part of Sweden famous for the heritage of the Sami indigenous people, who are known for their herding of reindeer. Not far from neighboring Norway, Riksgränsen literally translates into "The National Border" in Swedish.

While the resort offers 34 runs and six lifts, "The National Border" makes its name among those looking to go off trail and explore its 60 summits over 1,200 meters. A daylong off-piste tour of the surroundings goes for 895 krona per person, or about $110. You'll need three to six skiers to make a group. And starting in May, you can take advantage of midnight runs because, well, the sun never goes down that far up north during the summer.

Another unique offering at Riksgränsen is the snow and avalanche course. If you've always thought you could be better equipped safety-wise as you plan future off-piste excursions, consider spending a day perfecting your use of a transceiver, shovel and probe. It costs 995 krona (about $120).

Offering an amazing expanse of nearly unadulterated ice and snow, Lapland provides an intriguing experience for those looking to explore the world. But if you go, bring more than your usual winter gear. It's usually well below freezing.

Saint Anton, Austria :

Home of the 2001 Alpine World Ski Championships where the host country dominated the medal count in typical Austrian fashion,
