United States travel guide: when to go, where to go and how to plan it

November 8, 2026 · 9 min read

The United States is less one country to visit than a dozen. New York, the canyons of Arizona, the bayous of Louisiana, the redwood coast and a volcano in Hawaii are separated by flights of five or six hours, and they feel like different places with different weather, food and accents. The first rule of planning is to pick a region or two, not the whole map.

The second is that the country is built around cars and domestic flights, with a few good exceptions such as the north-east rail corridor and the big city subways. This guide covers when to go, where, a fourteen-day route from coast to coast, and what changes when you plan it with friends.

When to go

Because the country is so big, the best time depends on where you are going.

Spring (March to May) is good for most of the country. Washington's cherry blossom comes in late March or early April, the Southwest is warm and wildflowers bloom in the desert, and the national parks are open without the summer crowds. Higher mountains can still have snow into May or June.

Summer (June to August) is the busiest season and the one for national parks like Yellowstone, Glacier and Yosemite, where the high roads are open. It is also very hot in the Southwest, where temperatures in Death Valley and the Grand Canyon's inner canyon can be dangerous, and humid in the east and south. Hurricane season runs from June to November on the Atlantic and Gulf coasts, with the highest risk from August to October.

Autumn (September to November) is the favourite of many travellers. New England's leaves turn from late September to October, the Southwest cools, and the crowds thin after Labor Day, the first Monday in September. In October the New England coast and the Appalachians are at their best.

Winter (December to February) is cold and snowy in the north, with skiing in the Rockies, Utah and Vermont. It is the best time for Florida, southern California and the desert, and for Hawaii, though the north shores get big surf and some rain. New York at Christmas is magical and expensive.

Holidays fill hotels and roads: Memorial Day weekend, the Fourth of July, Labor Day and the long Thanksgiving weekend in late November. Many big parks now need advance reservations at peak times, so check the park's official site before you go.

Where to go

New York City

Five boroughs, an enormous subway and more to do than you can fit in a week. Walk the High Line and Central Park, cross the Brooklyn Bridge, see a Broadway show and eat your way across neighbourhoods. Stay in Manhattan for convenience or in Brooklyn for a quieter base. Four days is a good first visit. For a day-by-day plan, see the 4-day New York itinerary.

Washington, D.C.

The capital is compact and mostly free: the Smithsonian museums, the monuments on the National Mall, the Capitol and the neighbourhoods of Georgetown and Capitol Hill. Two days, or three if you love museums. It is easy by train from New York.

New Orleans

A city of music, food and architecture: jazz on Frenchmen Street, beignets, gumbo, the French Quarter and the garden district's old mansions. Visit in spring or autumn, as summer is hot and humid. Mardi Gras fills the city in February or March. Three days.

The Grand Canyon and the Southwest

The South Rim of the Grand Canyon is the classic stop, and nearby Arizona and Utah have Antelope Canyon, Monument Valley, Zion, Bryce and Arches. It is best by car, with long drives between parks. Spring and autumn are the best seasons. Plan on a week for the full loop, or two or three days for the Grand Canyon alone.

Yellowstone and Grand Teton

The first national park in the world has geysers, hot springs, bison and wolves, and the Tetons rise sharply just to the south. Wildlife is the reason to go, and the roads are open fully from late spring to early autumn. Allow four or five days and book lodging well ahead.

San Francisco and the Pacific coast

Hills, cable cars, the Golden Gate Bridge, ferries across the bay and wine in Napa and Sonoma. South of the city, Highway 1 runs along the cliffs of Big Sur to Santa Barbara and Los Angeles. Three days in the city and two on the coast.

Los Angeles

A sprawl of beaches, canyons, studios and neighbourhoods linked by freeways. Santa Monica and Venice for the sea, Griffith Observatory for the view, Hollywood for the legend and a long list of food worth the drive. You need a car or a lot of patience with ride-hailing. Three days.

Hawaii

A flight away from the mainland, each island has its own character: Oahu for Honolulu and surf, Maui for beaches and the road to Hana, Kauai for green cliffs and the Na Pali coast, and the Big Island for active volcanoes. Plan on a week for one or two islands. Respect closed trails and sacred sites, and check conditions at the beach.

A 14-day itinerary

Days 1–4: New York City. Arrive, spend a day on the downtown sights and the bridge, a day in Midtown and Central Park, and keep time for a show and a long dinner.

Days 5–6: Washington, D.C. About three to three and a half hours by train from New York. Spend a day on the Mall and its museums, and the next in Georgetown and the monuments at dusk.

Days 7–9: San Francisco. Fly across the country, about six hours. Cross the Golden Gate, ride a cable car, take the ferry to Sausalito and spend an evening in Chinatown or the Mission.

Days 10–11: Highway 1. Pick up a car and drive south through Monterey and Big Sur, with a night on the coast. Allow a full day of stops, as the road is slow and the views are the point.

Days 12–14: Los Angeles. About eight hours total from San Francisco with stops. Spend the last days on the beach, at the observatory and eating well, and fly home from LAX.

With more time, swap Washington for a Southwest loop of the Grand Canyon, or add a week in Hawaii at the end.

Getting around

Flying is the practical way to cross the country. Book internal flights early, and check how bags are charged, because low fares often exclude them. Airports are large and security lines can be long, so arrive early.

Trains are good in the north-east, where frequent services link Boston, New York, Philadelphia and Washington. Elsewhere, long-distance trains are scenic but slow and infrequent, so treat them as part of the trip, not a shortcut.

Driving is the way to see national parks, the Southwest and the coast. Roads are wide and easy, but distances are long: a day's drive can be eight hours. Drive on the right, speed limits are in miles per hour and you can turn right on a red light unless a sign says no. Most rental cars are automatic. See renting a car abroad and, for a longer route, plan a road trip.

Cities differ. New York, Washington, Boston, Chicago and San Francisco have good subways, buses or trams. In Los Angeles and most of the south and west, you will want a car or ride-hailing. Walking is pleasant in the older downtowns.

Money and costs

Cards and contactless payments are accepted almost everywhere, and many small places prefer cards. Carry a little cash for tips and small stalls.

Tipping is not optional, because staff wages assume it. In restaurants, 15 to 20 percent of the bill is the norm; taxi and ride-hail drivers, bartenders, hotel housekeeping and porters usually get a tip too. Prices on menus and shelves usually exclude sales tax, which is added at the till, and the rate varies by state and city. See tipping around the world for how this compares.

Hotels in big cities and near the major parks cost the most, and many add a fee on top of the room rate, so read the final price. Fast food, diners and food trucks are good value; healthcare is not, so insurance matters.

Rough daily costs a person, in 2026:

Budget: about US$100–160, with hostels or motels, cooking some meals and using buses and subways.
Mid-range: about US$200–350, with hotels, restaurant meals and a rental car shared between friends.
Comfortable: US$450 and up, with good hotels, guided tours and domestic flights.

Planning the United States as a group

The United States is easy for groups because everything is sized for cars, big tables and big rooms, but there are some things to settle early.

Rooms. Many hotel rooms have two queen beds and sleep four, which makes splitting a room across two couples or four friends cheap. For six or more, rent a house or an apartment through a rental site, or use a motel chain with connecting rooms.

Cars. A group of four to six can usually share one SUV or a minivan, which is far cheaper than two cars. Decide who drives and how to split fuel, parking and tolls.

Parks and tours. Popular parks, cable car rides, shows and tours sell out in season. Book the ones you really want first, and add the rest around them.

Restaurants. In big cities, a table for six on a Friday night needs a reservation, sometimes weeks ahead. Tipping on a big group bill is often added automatically, so check before you add it again.

Before you go

Entry rules: check the official government site of the United States and your own government's travel advice before you book, as requirements depend on your passport and nationality.
Travel insurance that covers medical costs, which can be very high for visitors. See travel insurance explained.
Connectivity: coverage is good in cities but patchy in national parks and the desert. An eSIM is the easiest route; download offline maps first.
A plug adapter for Type A and B if you come from outside North America, and check your devices handle 120 V; many chargers do, but some hairdryers and kettles do not.
Health: no vaccines are normally needed; ask a travel clinic. Bring any prescription medicines in their original packaging.
Customs: tip, and ask before taking a photo of strangers. Small talk with staff and neighbours is normal and friendly. Do not approach wildlife in parks, even if it looks tame, and keep to the trails.

What to pack

Bring layers for any season, since air conditioning can be strong indoors and temperatures swing in the mountains and the desert. Comfortable walking shoes are essential in cities, and sturdy shoes or boots for the parks.

For summer in the Southwest, a hat, sunscreen and a lot of water bottles; for the coast, a warm layer for fog; for winter, a proper coat, gloves and a hat. A refillable water bottle, a car phone mount and a charger for the car are useful on a road trip.
