Swiss Alps
Located in the heart of Europe with easy access from most major cities on the Continent, the Swiss Alps offer some of the world's most challenging skiing with incredible majestic views. Dare to shred the mountain terrain in hot ski towns like Zermatt and Chamonix. Mount the Matterhorn. And then take it all down a notch at après ski and a plunge in the hot tub. Life can be rough sometimes. Skiing shouldn't emulate that. The Swiss Alps, with its world-class resorts and healing spas, its towering peaks and deep valleys, its glam shopping and top dining, is truly a world wonder.

Great Smoky Mountains
Nestled between Tennessee and North Carolina, the Great Smoky Mountains are an oft-visited American treasure. With towering pines, vast wildlife (including black bears and elk) and Appalachian mountain peaks, the Smokies offer much to visitors, including daring hikes, rugged backpacking, horseback riding and biking. But for a true thrill, try your hand at globe riding. Did you ever think you'd enter a massive see-through orb and roll down a giant hill? With globe riding your dreams come true. And the Smokies, which are the exclusive globe riding locale in the U.S., make for an incredible setting-even if you'll likely be spinning too fast to see what's going on as you roll by.

Yosemite National Park
Moab may have its slickrock bike trails, Yosemite has its granite. This is one of the most spectacular locations in the world, with Half Dome towering over the land in the midst of the Sierra Nevada Mountains. Just a few hours between San Francisco and Los Angeles, Yosemite is a great getaway for any adventure traveler. Whether you're into camping, hiking or rafting, Yosemite offers something for everyone-even great lodging and dining right inside the park. Yosemite is built on massive slabs of granite, which make for intense rock climbing, bouldering and repelling. And the Yosemite Mountaineering School and Guide Service offers classes at all levels.

Alaska
When you want a true adventure, head to the pristine lands of Alaska. Miles and miles of uncharted territory await sports enthusiasts. Denali National Park sits as a gem in the middle of the state, offering diverse microclimates and rugged terrain, moose, bears and eagles soaring overhead. White water rafting is a sport of choice here and with more than 100,000 glaciers and 3,000 rivers, Alaska offers tremendous opportunity to get wet in the whitewater. If you want more from your Alaska adventure, you can canoe, go sport fishing or hike. For a heart stopping, blood rushing thrill, check out heli-skiing, where you're taking up into a helicopter and dropped in a remote area to ski back to civilization. It doesn't get more exhilarating that this!

Moab, Utah
Rising out of virtually nowhere, Moab is a sight in orange and red. This desert paradise in the middle of Utah beckons hikers, climbers and bikers from around the globe. Its adjacent proximity to Arches National Park makes it the perfect jumping off point for a multitude of outdoor activities. But beyond hiking and climbing the amazing desert arches, people flock to Moab to brave the slick rock. This is a bikers' paradise, whether on mountain or road wheels. The 12-mile-long Slickrock Bike Trail attracts more than 100,000 visitors per year to perform incredible death-defying runs down the side of the hills. Do you have it in you to take the challenge?

Hawaii's North Shore
Some people might find it insane to fly to the middle of the Pacific Ocean just to challenge some of the world's most intense surf breaks, but to diehards, this may as well be Mecca. Hawaii's North Shore captivates with its white sand beaches and turquoise waters. The surfing isn't without its dangers, including massive waves and shark-filled waters, but that's part of the thrill and adventure. When you want to catch a 12-foot swell and ride a half pipe, there's no better spot. The spirit of Aloha abounds in these waters and if you're lucky, you may even get to swim among wild dolphin.

Wahu, Wyoming
For anyone who has a fear of water but a need for speed, your new favorite sport is land sailing. Done on open vast plains, land sailing is quickly becoming a popular competitive sport. This activity is not for the faint of heart as racers, or pilots, can get up to speeds four times as fast as the wind propelling them forward. Since dry lakebeds and deserts are the ideal locale, this spot in Wyoming has become a destination du jour for North American land sailors. Its proximity to Wahu gives it easy access, but because it's seemingly in the middle of nowhere, you know you'll be surrounded by people who love the sport as much as you.
