Choosing Your Route
The United States has several iconic road trip routes. Route 66 (Chicago to Los Angeles) is the most famous, passing through the American heartland. The Pacific Coast Highway (US-101 and CA-1) offers spectacular ocean views from San Francisco to Los Angeles. The Blue Ridge Parkway winds through the Appalachian Mountains. The Great River Road follows the Mississippi River. Choose a route based on your interests, time available, and starting point.
Renting a Car
Most international visitors will need to rent a car for a US road trip. Major rental companies (Enterprise, Hertz, Avis, Budget, National) have locations at all major airports and in city centers. Book in advance for the best rates. An international driving permit (IDP) is recommended for non-US license holders, though requirements vary by state. Check your personal auto insurance and credit card benefits before purchasing the rental company's coverage.
Driving in the USA
Americans drive on the right side of the road. Speed limits are posted in miles per hour (mph). Interstate highways (I-) connect major cities and are the fastest routes. US highways (US-) and state routes offer more scenic alternatives. Fuel (gasoline) is sold in gallons and is generally affordable compared to European prices. Most rental cars require regular unleaded fuel.
Accommodation
Road trip accommodation options include motels (affordable, roadside), chain hotels (consistent quality), boutique hotels (unique experiences), campgrounds (national and state parks), and vacation rentals. Booking in advance is essential during summer and holiday periods. National Park campgrounds often require reservations months in advance.
National Parks
The US National Park System includes over 400 sites. The America the Beautiful pass ($80 per year) provides access to all national parks and federal recreation areas and is excellent value for road trippers visiting multiple parks. Popular parks include Yellowstone, Grand Canyon, Yosemite, Zion, Bryce Canyon, Arches, and Great Smoky Mountains.
Key Tips
Download offline maps (Google Maps, Maps.me) before your trip — cell coverage can be limited in rural areas.
The America the Beautiful annual pass ($80) pays for itself after visiting just two or three national parks.
Book accommodation in advance for national park areas — options near popular parks sell out months ahead.
Allow more time than you think you need — the US is vast and distances between attractions are often greater than they appear on a map.
