27 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.

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.

Straddling the border between California and Nevada, Lake Tahoe draws visitors from both states and beyond to its shores. With an average of 300 sunny days annually, it's no surprise that the lake is a favorite among outdoor enthusiasts. The blue-green waters beckon travelers for swimming, boating, windsurfing, or kayaking. The lake also has a number of walking trails for those who don't want to get wet. In the colder months, skiers take to the surrounding mountains. The south shore is the most developed side of the lake, with more things to do, while the west and north shores are generally more tranquil.

Separated from major metropolitan areas, coastal San Luis Obispo County has preserved its rural character. It includes many small communities with a strong agricultural heritage, and preserves a sense of old California. Many visitors on holiday come here to browse the excellent farmers' markets or tour world-class vineyards. The county offers plentiful outdoor vacation ideas, with beaches, rolling hills, and the Santa Lucia mountain range nearby. You can also take side trips to the area's larger towns, with their historical downtown districts, shopping destinations, and museums.
