38 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.

Divided by law, geography, and custom into three major regions, represented by the three stars on state's flag, Tennessee boasts a distinctive musical heritage that includes elements of bluegrass, country-western, and blues. With a countryside as diverse as its people, Tennessee includes landscapes ranging from a mountainous region in the east to the lowlands of the west, with gently rolling hills in the middle. For a well-rounded vacation, you can hike remote mountain trails in the morning and explore the crowded bars of Nashville in the evening. Visit the urban attractions, such as Elvis Presley's former residence in Memphis, but don't miss a chance to spend some time in the Great Smoky Mountains National Park, situated in the eastern part of the state.

Thanks to its size and geologic features, Texas contains diverse landscapes that closely resemble both the south and southwest of the United States. Though most people associate Texas with tracts of barren land, deserts cover only about 10 percent of the state, with most of its big population centers located in areas once covered by prairies, grasslands, and forests. As you travel from one end of Texas to the other, observe the changing terrain that ranges from coastal piney woods and swamps in the east to the mountains of the west, with rolling plains and rugged hills in the center. For a bit of urban sightseeing visit some of the state's large cities such as Houston, Dallas, or Austin, or immerse yourself in the nation's history by adding famous attractions like The Alamo to your itinerary. Take plenty of time to mingle with the locals, famous for their hospitality, generosity, and fiercely independent spirit.

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.
