About United States

United States at a glance

The United States has some of the world's best-known mountain landscapes, many protected as national parks. This guide starts with two: Yosemite in California's Sierra Nevada, known for granite cliffs and waterfalls, and Grand Teton in Wyoming, where a jagged range rises straight from a valley.

Distances are large, and most visitors rent a car. Parks charge entrance fees (an annual pass can pay for itself on a longer trip), and popular parks may use reservation systems on busy dates, so check each park's official page.

Summer is the main season for high-country hiking, with spring best for Yosemite's waterfalls and autumn for colour. Winter is for skiing at resorts such as Jackson Hole, and many park roads close. Book lodging and campsites well in advance for summer.

Getting there

San Francisco (SFO), Los Angeles (LAX) and Las Vegas (LAS) are the main international airports for the Sierra Nevada, with Fresno (FAT) the closest for Yosemite. Salt Lake City (SLC) and Denver (DEN) serve the Rockies, and Jackson Hole (JAC), inside Grand Teton National Park, has regional flights.

Getting around

A rental car is the easiest way to reach most national parks. Some parks run free shuttles in busy areas, and seasonal buses serve a few gateway towns, but these are limited, so check before you rely on them.

Entry and safety

Entry rules depend on your nationality. Many visitors need a visa or an approved travel authorisation (ESTA) before flying, so check the official US government information well in advance.

Wildlife, weather and altitude are the main risks. Keep your distance from animals, store food as the park requires, carry bear spray where recommended, and check the park's official page for fires, road closures and trail conditions. Call 911 in an emergency.
