Planning a backpacking route through the USA can be tricky — you need to balance must-see places, travel times, budget, and how long to stay in each destination. Our free personalized the USA itinerary planner creates a route based on your travel style, trip duration, and interests, so you can spend less time researching and more time exploring.
Personal tip: I normally search on good rating for atmosphere (for meeting people) and location (for easy exploring). Cleanliness as a bonus.
Travel Essentials
No vaccinations are required to enter the United States as a tourist, and there is no COVID-19 vaccine requirement for foreign visitors. Health authorities recommend being up to date on routine vaccines, especially measles (MMR), since outbreaks have occurred in several states, plus tetanus, flu and COVID-19 boosters. Hepatitis A and B are worth considering for longer trips. Because medical care in the US is extremely expensive, solid travel insurance matters more than any extra shot.
vaccination requirementsWhen I first started traveling, I often spent part of my first day in a new country hunting for a local SIM card. While this can still be slightly cheaper, it also takes time and planning.
These days, it's much simpler to install an eSIM before leaving home. Once you arrive in the USA, you can activate it immediately and have mobile data from the moment you land — which is especially useful for ordering transport or navigating away from busy airports.
There are many providers nowadays, and price differences are usually small. I personally go with
Holafly, as it offers excellent network coverage throughout the country and strong global coverage, so you can manage multiple countries from a single app.

Americans value personal space, so keep about an arm’s length when talking and avoid touching strangers. Do line up patiently and wait your turn, whether at a coffee counter or a bus stop, since cutting a queue is a serious faux pas. Do expect friendly small talk from strangers and servers; it’s normal politeness, not flirting or a sales trick. Don’t drink alcohol in public streets or parks in most states, and carry ID, because bars routinely check it even if you look well over the drinking age of 21. Avoid bringing up politics, religion or guns with people you’ve just met, as these topics can turn heated quickly. Smoking is banned indoors in most public places and many states also restrict it outdoors near entrances. Public displays of affection between same-sex couples are common and accepted in big cities, while more discretion is wise in small conservative towns; women can dress as they like in cities, though modest clothing suits churches and some rural areas.
Trying traditional food is always a great way to experience the culture. Here are some must-try dishes for the USA.
- Hamburger: A ground-beef patty in a soft bun with cheese, pickles and onions. It’s the country’s default comfort food, from US$5 drive-through versions to thick diner burgers, and every region argues about the best one.
- Barbecue: Meat smoked low and slow for hours over wood. Texas does beef brisket, the Carolinas pulled pork with vinegar sauce, Kansas City sweet tomato-sauced ribs, and Memphis dry-rubbed ribs; regional loyalty runs deep.
- Southern fried chicken: Buttermilk-soaked chicken fried until the crust shatters, usually served with biscuits, collard greens or mac and cheese. It’s a cornerstone of African American and Southern home cooking.
- New York-style pizza: Wide, thin slices you fold in half and eat on the street, typically US$3 to 5 each. Born from Italian immigrant bakeries, it’s the city’s cheapest reliable meal.
- New England clam chowder: A thick, creamy soup of clams, potatoes and salt pork, best in Boston and coastal Maine, often served in a sourdough bread bowl in San Francisco.
- Tex-Mex and burritos: Cheese-heavy enchiladas, fajitas and chili con carne in Texas, and huge foil-wrapped Mission-style burritos in San Francisco. These dishes show how deeply Mexican cooking shapes American food.
- Apple pie: A flaky crust filled with cinnamon-spiced apples, often topped with vanilla ice cream (“à la mode”). It’s so tied to national identity that “as American as apple pie” is a common phrase.
Tap water in the United States is safe to drink almost everywhere, and most locals drink it straight from the tap or from water fountains, with restaurants serving free ice water by default. It’s fine for tourists too, though it can taste of chlorine in some cities, which is why many Americans use filter pitchers. Bottled water is only advised during occasional local “boil water” notices, at some private rural wells, or for untreated stream water in national parks, which should always be filtered.
English is the main language everywhere in the United States, so you’ll manage without effort in Washington D.C., New York, tourist hubs, hostels and the most remote rural diner alike. Regional accents and slang vary a lot (fast talkers in New York, slow drawls in the Deep South), but people will happily repeat themselves. Spanish is the most useful second language, spoken widely in Miami, Southern California, Texas and the Southwest, where a few phrases earn smiles in markets and taquerias. If English isn’t your first language, Google Translate’s conversation mode covers the gaps, and asking “Could you say that again?” is perfectly normal.
Money & Payments
The local currency of the USA is USD ($).
ATMs are everywhere in the United States, in banks, gas stations, supermarkets and convenience stores, but non-bank machines charge US$3 to 5 per withdrawal on top of your home bank’s foreign fee, so stick to bank-branded ATMs and take out larger amounts less often. Cards are accepted almost universally, contactless and Apple or Google Pay work at most shops, transit systems and restaurants, and some cafés and stadiums are fully cash-free. Keep US$40 to 60 in small bills for food trucks, farmers markets, laundromats, tips and the occasional cash-only bar or rural motel. Bring US dollars or simply rely on cards, because euros and other currencies are hard to exchange outside major airports and big-city banks. If you need to exchange, use a major bank branch, which gives far better rates than airport kiosks, and choose to be charged in dollars when a card machine offers your home currency.
Tipping in the United States is expected rather than optional, because servers and bartenders earn low base wages and depend on tips: leave 18 to 20% of the pre-tax bill at sit-down restaurants, US$1 to 2 per drink at bars, and 15 to 20% for taxis, rideshares and hairdressers. Hotel housekeeping usually gets US$2 to 5 per night, and hostel staff typically don’t expect tips. Tablet screens at counter-service cafés will suggest a tip too, but at those places tipping is a nice gesture, not an obligation.
