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.

The “Sunshine State,” Florida became a favorite winter destination for the affluent crowd over a century ago. Today, the state attracts visitors from around the world with its golden beaches and modern theme parks. You can spend your entire vacation enjoying the state's highly developed seaside areas, but remember that some of Florida's best-kept secrets are in secluded locations. Visit the big cities and their comfortable resorts offering top-notch dining and nightlife, but leave some time to see the peninsula's swampy landscape, filled with wild creatures and native plants. Farther away from the tourist-packed urban areas, the untamed wetlands of Florida offer a selection of things to do, such as kayaking, boat rides, and numerous other outdoor activities.

The country's most populous state, California includes landscapes that range from the forested northern coast to harsh southern deserts. Sandwiched right in the middle of the state is a fertile valley, home to farms, vineyards, and orchards. California's cities offer diverse attractions, from amusement parks and upscale shops to award-winning restaurants and innovative art galleries. Outside the state's big urban centers, places to visit include some of the nation's most rugged national parks, ancient forests, towering mountain peaks, and ski resorts. More than just a surfing destination famous for its beaches and winding coastal roads, California also boasts one of the world's largest economies, bolstered by the booming tech industries.

An archipelago of hundreds of volcanic islands located in a geological hot spot in the middle of Pacific, Hawaii offers diverse natural scenery and a warm tropical climate. The six major islands open to tourism draw visitors with their sun-drenched public beaches and craggy natural trails. Thanks to their mid-Pacific location, the islands boast a vibrant native culture influenced by both North America and Asia. You can spend your vacation basking in the modern comforts of the big hotels, but to experience the true spirit of these islands, remember that real Hawaiians live outdoors. Encounter nature by surfing, swimming, fishing, and picnicking, or join a guided tour across the ancient lava flows to the top of Hawaii's rugged volcanic peaks.
