15 days in United States Itinerary

More than the country of car-packed streets seen in TV shows and movies, the United States of America is a complex and diverse home to over 300 million people living in a wide range of landscapes and climates. From its big-city skyscrapers to its sprawling natural parks, the country's ''melting pot'' combines many ethnic groups that share a strong sense of national identity despite their cultural differences. A country of road trips and big blue skies, the United States harbors orderly cities filled with restaurants, parks, museums, and innumerable sightseeing opportunities, as well as pristine natural areas perfect for a holiday in the great outdoors. To see as much as you can of this diverse land quickly, drive over some of the more than 6 million km (4 million mi) of highways leading through deserts, mountain peaks, fertile fields, and giant urban centers.

A land of many faces, Oregon is at once a state of rugged rocky coastlines and deep forests, as well as vibrant cities and small towns packed with award-winning restaurants and trendy shops. With nearly half of its land covered by dense fir, redwood, and pine forests, the state protects varied plant and animal life inside three national parks. In addition to pristine waterfalls, beaches, and lakes perfect for a holiday in nature, Oregon also offers numerous urban tourist attractions. Portland, the state's largest metropolis, notably includes more breweries than any other city in the world, and its central location makes it an ideal base for day trips to Oregon's emerging wine region and many parks.

With a population of only one million, Montana remains an untouched natural paradise of snowcapped peaks, expansive forests, and alpine lakes, dotted with Old West ghost towns, Indian reservations, and progressive urban communities. Appreciate the state's unique charm and beauty with a trip to Glacier National Park, where you can come face-to-face with Montana wildlife among its high peaks. Head to the state's largest cities, Billings and Missoula, for an array of historical attractions and cultural sightseeing.

Still largely undiscovered by foreign tourism, Wyoming is anything but "the bunchgrass edge of the world," as a writer once called it. Though the state's geography includes mostly wide-open plains, swaths of high desert, and sweeping mountain ridges, it also contains many small towns filled with places to visit, such as historical buildings, museums, shops, and restaurants. A great place to discover the last vestiges of the Old West, Wyoming's tourist attractions include the country's first national park, Native American reservations, and a smattering of ghost towns from the early frontier days. As you travel across this "Cowboy State," remember that distances between towns can be vast, requiring more advance vacation planning than travel in more densely populated parts of the country.

Home to diverse natural ecosystems, Colorado boasts numerous ski resorts, vineyards, canyons, fossil-rich national parks, rugged natural trails, and picturesque scenic drives. Arguably the greatest of Colorado's many natural wonders is Mt. Elbert, the highest peak in the North American Rockies. The state's natural beauty inspired the opening lyrics of the song "America the Beautiful." Aside from its abundant unspoiled wilderness, Colorado also offers many urban attractions, including award-winning restaurants and nationally praised microbreweries. With an extensive system of highways and railroads, the state provides visitors on vacation with a chance to explore this largely untamed part of the country by car or train.

A huge but sparsely populated land, Utah remains a major holiday destination offering plenty of year-round outdoor vacation ideas, including skiing, snowboarding, hiking, boating, horseback riding, and camping. The rugged terrain, defined by towering mountain peaks, deep canyons, and vast deserts, seems custom-made for adventurous nature lovers. With five national parks, the state has no shortage of pristine wilderness areas, causing many tourists to overlook the cultural attractions of its towns. Salt Lake City, the state's capital, features the headquarters of the Mormon Church, and draws over 5 million annual visitors. Utah also hosts several major film festivals each year, attracting young movie buffs from around the world.
