United States

The United States rewards focused itineraries: trying to combine New York, Yellowstone, New Orleans, and Los Angeles in one trip usually means spending more time in airports than neighborhoods. Choose one region—such as the Northeast, Southwest, Pacific Coast, or Southeast—and build around two or three bases. Hello’s trip-planning tools can help organize flights, hotels, museum reservations, and day trips in one place.

Before booking, check the entry rules that match your passport and travel purpose. Citizens of participating Visa Waiver Program countries may visit for tourism or business for up to 90 days, but they need an eligible e-passport and approved ESTA authorization before travelling; U.S. Customs and Border Protection recommends applying early. Other travellers may need a visa, so confirm requirements through official U.S. government channels.

Pack for regional variation. San Francisco can be cool in summer, Florida is humid, and desert parks may be scorching by day but chilly after sunset. Reserve popular national-park accommodation, Broadway tickets, and major attractions well ahead, especially during school holidays.

Transport depends heavily on the region. In New York City, Washington, D.C., Boston, Chicago, and San Francisco, public transport is often the easiest option. In Los Angeles, Miami, Phoenix, and many national-park gateways, a rental car can save time—but factor in parking, fuel, tolls, and one-way drop-off fees.

Domestic flights are practical for long distances, yet airports can sit far outside city centres. Arrive early for security and allow extra time for checked baggage or connections. For a slower journey, Amtrak links major cities and reaches destinations near several national parks; the National Park Service highlights train-based options for exploring its park network.

A few habits make road travel smoother:

• Keep your driving licence, rental documents, and insurance details accessible.
• Check whether toll roads charge automatically; ask the rental company how billing works.
• Download offline maps before entering remote areas.
• Never underestimate distances: Texas, Alaska, and the western states are vast.

An Hello eSIM activated before landing is useful for navigation, rides, reservations, and emergency calls without relying on airport Wi-Fi.

Eating across the United States is a journey in itself. Try New York pizza, a Chicago deep-dish pie, Texas barbecue, Louisiana gumbo, New England lobster rolls, Korean barbecue in Los Angeles, and regional tacos in San Diego or Austin. Farmers’ markets and food halls are often excellent ways to sample local specialties without committing to a formal meal.

Prices on menus usually exclude sales tax, which varies by state and sometimes by city. Restaurants commonly expect a tip of around 15–20% for table service, with higher amounts possible for exceptional service. Check the bill before paying: gratuity may already be included for large groups. Tipping customs also apply to bartenders, hotel staff, guides, and drivers.

Use U.S. dollars for budgeting and keep a small amount of cash for markets, small cafés, or older transport systems. Card payments are widely accepted, but your bank may add foreign-exchange fees. Hello’s budget-tracking feature lets you record spending in local currency, while expense splitting can simplify shared hotel rooms, rental cars, and group dinners.

The United States has outdoor experiences for nearly every travel style: sunrise over the Grand Canyon, geysers in Yellowstone, granite cliffs in Yosemite, autumn forests in New England, and coastal trails along California’s Highway 1. National parks can be crowded, so check each park’s current reservation, shuttle, and vehicle-entry requirements before setting out.

Plan conservatively in remote areas. Carry more water than you expect to need, bring sun protection, and tell someone your route when hiking beyond a busy trailhead. Mobile coverage can disappear quickly, so download maps and park information in advance. Weather can change rapidly in mountain and desert environments; a short trail at midday may become dangerous after a storm or heat spike.

Start hikes early for cooler temperatures, easier parking, and better wildlife-viewing opportunities. Never feed animals, keep a safe distance, and follow posted rules—especially around bears, bison, and hot springs. Hello eSIM connectivity can help with directions and updates, but treat it as a convenience rather than a guarantee of service in wilderness areas.
