Top destination 2025: The United States (USA) — iconic cities, grand parks & legendary road trips

From the skyscrapers of Manhattan to the arches of Utah, from Yellowstone geysers to California beaches, the United States is a world destination dreamed in widescreen. This 2025 guide gives you the keys: when to go, where to go (coasts, deserts, forests, islands), how to get around, how much to budget, what to respect — all with ready-to-use itineraries. The images are distributed by section and link to stable public URLs (Wikimedia), all unique.

Geography & major regions

The fourth largest country in the world by area, the United States of America unfolds a mosaic of landscapes: Atlantic & Caribbean coastlines, Appalachians, Great Plains, Rockies, Southwest deserts, temperate forests of the Pacific Northwest, not to mention Alaska and its boreal expanses, and Hawaii, a volcanic archipelago in the middle of the Pacific. Time zones-wise, the “contiguous U.S.” stretches from UTC-5 (East) to UTC-8 (Pacific) — not counting Alaska (UTC-9) and Hawaii (UTC-10).

Conveniently, 8 major tourist areas are distinguished:

• Northeast (New York, Boston, Washington, Philadelphia, Niagara);
• Southeast (Florida, Georgia, Louisiana, Carolinas);
• Midwest (Chicago, Great Lakes, historic Route 66);
• Rockies (Colorado, Wyoming, Montana, Idaho);
• Southwest (Arizona, Utah, Nevada, New Mexico, inland California);
• Pacific Coast (California, Oregon, Washington);
• Alaska (glaciers, arctic wildlife, fjords);
• Hawaii (beaches, volcanoes, Polynesian culture).

Useful vocabulary — ZIP code = postal code; State = federal state; County = county; National Park = national park; Scenic Byway = scenic route.

Historical landmarks & heritage

The territory has been inhabited for millennia by indigenous peoples (Navajos, Hopis, Cherokees, Sioux, Haidas… depending on the regions). In the 17^th century, European colonies were established (mainly British, but also French and Spanish); the Declaration of Independence (1776) founded a new state, followed by a federal Constitution (1787). The 19^th century was that of the Frontier, the transcontinental railroad, the integration of vast territories, but also the Civil War (1861–1865) at the heart of the young nation. The 20^th century saw industrial rise, the Hollywood golden age, the civil rights movement, and the rise of a global popular culture (jazz, rock, hip-hop, comics, NBA…).

For the traveler, these layers are read in contrasting heritages: colonial centers of the Northeast (Boston, Philadelphia), national monuments (Mount Rushmore, Statue of Liberty), world-class museums (Smithsonian in Washington, MoMA/Met in New York, Art Institute in Chicago, Getty in L.A.), and above all a unique network of national parks (Yellowstone, Yosemite, Grand Canyon, Zion, Arches, Bryce, Glacier, Acadia…).

Population & practical information

The USA has about 330–335 million inhabitants (approximate figure for 2025), spread across 50 states + District of Columbia. The demonym is American; the major metropolitan areas are New York, Los Angeles, Chicago, Houston, Phoenix, Philadelphia, San Antonio, San Diego, Dallas, San José.

Climate & when to go

It is impossible to talk about a single climate: you cross almost all zones, from polar (Alaska) to tropical (Florida, Hawaii), through arid (Arizona/Nevada deserts), humid continental (Midwest) and oceanic (Northwest). For a first trip, keep in mind:

• Spring (March–May): ideal for the South (Florida, Louisiana, Texas) and Northeast cities (blooming, mild temperatures).
• Summer (June–Sept.): peak season for the Rocky Mountain parks (Idaho, Montana, Wyoming, Colorado) and the Pacific/Atlantic coasts; heat/crowds in the Southwest (prefer early/late visits).
• Autumn (Sept.–Nov.): Indian summer in New England, beautiful contrasts in the West; possible hurricanes in the Atlantic/Caribbean (watch the season).
• Winter (Dec.–Feb.): skiing in the Rockies/Sierra Nevada; city breaks (NYC, Chicago) with marked cold; mild climate in Southern California and Florida.

Must-sees by region (top 10)

1) New York City (Northeast)

The city that never sleeps: Manhattan (Central Park, museums, Broadway, Brooklyn Bridge), Harlem (gospel, jazz), Brooklyn (DUMBO, Williamsburg), Staten Island (free view from the ferry). A trip to Liberty Island and Ellis Island sheds light on the immigrant saga.

Tip — For a cinematic view of Midtown, go up to the Top of the Rock (Rockefeller Center) at sunset: the Empire State lights up facing you.

2) Washington, Philadelphia & Boston (Historic Northeast)

Boston’s Freedom Trail, the Declaration of Independence in Philadelphia, the free museums of the National Mall in Washington (Smithsonian): an America of ideas and struggles (slavery, suffragettes, civil rights) is revealed.

3) Florida & Southeast

Between Miami Art Deco, the Keys (Caribbean atmosphere at the end of the Overseas Highway), Everglades (subtropical ecosystems) and Orlando’s theme parks, Florida combines beaches, mangroves, and XXL entertainment.

4) Chicago & Great Lakes (Midwest)

Bold architecture on Lake Michigan (School of Architecture), top-level science and art museums, blues and deep-dish pizza. Nearby: Milwaukee, reborn Detroit, Cleveland (Rock & Roll Hall of Fame).

5) California & Pacific Coast

San Francisco and its dramatic terrain, Los Angeles (cinema, Santa Monica beaches, street art), San Diego (mild climate). Further north, the Pacific Coast Highway unfolds cliffs, sequoias, and bays.

6) American West & Deserts (Arizona, Utah, Nevada, New Mexico)

The Western dream: Grand Canyon, Zion, Bryce, Arches, Monument Valley, Antelope Canyon, Death Valley, dunes of the Great Sand Dunes. Scenic drives, mineral arches, and vast skies mark the days; nights under the Milky Way.

7) Rockies & Major Parks (Colorado, Wyoming, Montana, Idaho)

Yellowstone (Old Faithful geyser, bison, wolves), Grand Teton (jagged peaks, lakes), Glacier (glacial cirques), Rocky Mountain (high mountain passes): alpine and wild America.

8) Pacific Northwest (Oregon, Washington)

Mossy forests, Mount Rainier volcano, wild Oregon coasts, Seattle cafés, Willamette Valley vineyards. Oceanic climate, noir novel atmospheres, whales offshore.

9) Alaska

Glaciers, fjords, bears, orcas, Denali and Inside Passage. Short summer, endless light; more expensive logistics but unparalleled spectacles.

10) Hawaii

Polynesian culture, beaches and active volcanoes (Hawai‘i Volcanoes). Surfing, trails in sculpted valleys (Kauai), turtles and manta rays while snorkeling (Big Island, Kona).

Transport, access & formalities

Coming from France/Belgium/Switzerland

Frequent direct flights to New York, Boston, Washington, Chicago, Miami, Los Angeles, San Francisco, Seattle… European hubs (London, Amsterdam, Frankfurt, Madrid, Istanbul, Doha, Dubai) offer multiple combinations.

Formalities

• ESTA (visa waiver program) often required for tourist stays < 90 days — biometric passport, online application before departure. Some nationalities or situations require a visa; always check the official rule.
• Customs & security: CBP/TSA checks, declarations of goods, food/use restrictions (liquids in cabin, etc.).
• Driver’s license: national license + international license recommended; minimum rental age varies according to rental companies/states.

Getting Around

• Plane: dense network of domestic routes to “hop” between regions.
• Car: queen of inter-park travel; right-hand driving, speed limits in mph, caution for wildlife and weather in high altitude/desert areas.
• Train: Amtrak useful on certain routes (Northeast, California, scenic trips).
• Bus: economical options (intercity lines).
• Cities: efficient subways (NYC, DC, Chicago, partially SF), ride-hailing/taxis, bikes in increasingly bike-friendly downtowns.

National parks — Consider the annual pass that covers most parks managed by the National Park Service. Reservations are now mandatory for certain roads/entrances in high season (Yosemite, Arches, Glacier… depending on the year).

Budget, Accommodations & Tips

The cost varies greatly depending on the season, city/state, and travel style. Accommodations range from roadside motels to lodges in the parks (highly sought after), including campgrounds, B&Bs, and urban hotels. Dining options range from very affordable (diners, food trucks) to starred restaurants. The most common paid activities include: museum entries, wildlife watching, cruises, NBA/MLB/NFL games, guided tours, equipment rentals (kayak, bike, snowshoes…).

Tips: in the USA, tipping is part of servers’ income. At table service restaurants, a gratuity is generally expected; for taxis/ride-hailing, bars, concierges, guides, hairdressers, tipping is customary. Sales taxes (State/City) are added at checkout: a displayed price does not necessarily include tax.

Local Life & Pop Culture

The USA is diverse: regional cuisines (Texas barbecue, Cajun-Creole, bagels, soul food, Pacific fusion), music (blues, jazz, country, hip-hop), sports (NBA, NFL, MLB, NHL), urban parks (Central Park, Balboa Park, Golden Gate Park), microbreweries and specialty coffee shops. Festivals mark the year: Mardi Gras (New Orleans), South by Southwest (Austin), Coachella (California), Balloon Fiesta (Albuquerque), Cherry Blossom (Washington).

“Scenic” Label — The National Scenic Byways and All-American Roads highlight exceptional routes: Overseas Highway (Florida Keys), Trail Ridge Road (Rocky Mountain NP), Blue Ridge Parkway (Appalachians), Pacific Coast Highway (California)…

Sustainable Travel in the USA

• Favor compact itineraries (fewer domestic flights), combine train/bus when relevant.
• Choose committed accommodations (water/energy saving, recycling), certified nature operators (wildlife watching, tribal guides).
• Respect Leave No Trace principles: stay on trails, take nothing, no drones without authorization in parks, keep a safe distance from wildlife (bison, elk, bears… depending on the park).
• Use “reef-safe” sunscreens in Hawaii; limit plastic (filtered water bottle).
