The Alta Via No. 1, in the Dolomites of northern Italy, offers exquisite valley views and crosses breathtaking summits from Braies Lake, near Dobbiaco, to Passo Duran, for a total of 75 miles. Each night you sleep in a cozy rifugio where warm beds and meals await. Great Walks of the World (011-44-19-3581-0820, www.greatwalks.net) offers a ten-day all-inclusive hike for $1,700.
The Haute Route, a seven-day, 70-to-90-mile trek from Chamonix, France, to Zermatt, Switzerland, comes in two flavors: the glacier option, which includes travel on snow and ice, and the hiking version, which stays on established trails. Both routes offer stunning views of the French and Swiss Alps and end in the shadow of the Matterhorn. Reserve early at each night's hut or sign up with an outfitter like Chamonix Experience ($1,700; 011-33-6-08-80-94-27, www.chamex.com).
The Stubai Horseshoe, a 45-mile traverse of Austria's incredibly scenic Stubai Valley, south of Innsbruck, is a hiker's dream. The relatively strenuous seven-day circuit starts in the village of Obertal and ends in Neustift. On Top Mountaineering (800-506-7177, www.ontopmountaineering.com) offers an all-inclusive weeklong trip for $1,900.
