How Long Would It Take to Walk Across the US?

Are you planning to walk across the U.S., or perhaps are you just curious how long it would take? Let us explore together the available routes out there and find out how long it would take to walk across the U.S. using the different routes. 

How long would it take to walk across the U.S.? If you walked for about 6 hours a day, in a straight line from New York to L.A. (2,448 miles), it would take about 4 to 5 months. But walking in a straight line is not possible due to obstacles and private property. 6 to 9 months is a more common timeframe depending on the route.

I’ve listed below 6 routes that span from coast to coast (East-West). Most of these routes are along a highway, so meant for driving. Walking on a highway is illegal in the U.S., but you can walk alongside the highway or near to it in order to follow the route.

I also list 4 North-South routes. If you don’t want the longer coast-to-coast trek, you can choose a North-South route instead.

Read on to learn more about how long it would take to walk across the US using 10 different popular routes.

How Long Would It Take to Walk Across the US?

From America’s coast to coast, the distance is greater in the northern latitudes than southern latitudes. If we measure the distance between New York and Los Angeles, it is 2,448 miles / 3,940 kilometers.

A comfortable walking speed on flat ground is about 3 miles per hour. Let’s say you walked 6 hours a day, so 6 hours x 3 miles per hour = 18 miles per day. So to walk the New York to L.A. distance of 2,448 miles, divide 2,448 by 18 to get 136 days, about 4.5 months.

This straight path distance from New York to L.A. is unrealistic due to the terrain and private property. So a more realistic estimate, if you walked about 6 hours a day, would be about 6 or more months. Some people have walked across the US in about 6 or 7 months, and some stretch out their hike to a year to enjoy their journey. The length of time will increase based on how much you want to walk each day and how long you want to stop in an area to sightsee.

The length of time it’ll take you to walk across the US also depends on the route you choose. Below is a list of routes you can take if you’re planning to dive into this journey.

East-West U.S. Routes (Coast to Coast)

1. U.S. Route 20

how long to walk across the us

U.S. Route 20, also known as U.S. Highway 20, is an east to west route that stretches 3,365 miles / 5,415 km from Massachusetts to Oregon. U.S. Route 20 is considered the longest highway that offers a transcontinental journey. The road offers you a glimpse of popular cities and must-see landscapes in the country.

Route 20 goes through Massachusetts, New York, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Nebraska, Wyoming, Montana, Idaho, and Oregon. This path takes you to the Boston Post Road in Massachusetts, which was the path taken by those people carrying mail from Boston to New York City during the 17th and 18th centuries.

In New York, you’ll pass through lakes and rural landscapes. As the route continues west, it takes you to Indiana Dunes National Lakeshore [1], to the industrialized Gary, Indiana, urbanized South Side Chicago, to Wyoming and the amazing Yellowstone National Park.

The route allows you to pass through Montana, Idaho, to the Craters of the Moon National Monument [2], and finally to Oregon. The route takes you less than a mile from the Pacific, where it ends. 

This route is designed for driving; however, if you were to walk this route, it would take at least 5 or 6 months. Remember though that it is illegal to walk on the highway in the US, unless for someone with emergency car trouble. So you would need to walk alongside or near this highway, not on it, to follow this route.

2. American Discovery Trail

The American Discovery Trail (ADT) is a coast-to-coast non-motorized route (the one and only route that is specifically designated for non-motorized, so for traveling on foot) that gives people a glimpse of states, deserts, cities, small towns, and National Parks.

This trail is different from the Appalachian or Pacific Crest Trails because it does not pass through only the wilderness. Instead, as mentioned, this trail allows you to pass through farmlands, towns, cities, etc.

This trail is one of the most popular trails for this reason, and for being the most accessible trail in the country. What makes it more popular is that this route is open for activities such as hiking, biking, and horseback riding. ADT links up with other existing national trails such as the Appalachian, Pacific Crest, and Santa Fe trails. 

To cross from one side of the U.S. to another, you have an option to take the route that is 4,834 miles long and the other route which is 5,057 miles long. The trail is about 6,800 miles in total. Whichever option you choose, you are still passing from Cape Henlopen State Park in Delaware to Pt. Reyes National Seashore, California.

Along the trail, you’ll be able to have a glimpse of Devonian-age fossil beds, a Native American village, Abe Lincoln’s childhood home, the world’s second-largest clock, and lastly North America’s largest inland boat builder.

3. Southern Route

If you want a route that will not require you to hike elevated areas (except for the Appalachians), choose the Southern Route. The route is about 2,671 miles and starts in San Diego, located between the border of California and Mexico. This route allows you to go through the arid deserts of Arizona, New Mexico, and northern Texas. 

The route will eventually lead you through the cotton fields of northern Louisiana, the plantations located in Mississippi, and the prairies of Alabama. The route ends in Georgia, located in the coastal town of Savannah.

4. U.S. Route 6

U.S. Route 6, otherwise referred to as the Grand Army of the Republic Highway, is a historic route that honors the American Civil War veterans association. The original route runs from the waterfront in Long Beach, California, and stops at Provincetown, Massachusetts, which can be found at the tip of Cape Cod.

If you choose this path, you will be able to pass 14 states and travel about 3,652 miles long, with a high point of 11,990 feet. The route is estimated to have 100,000 prehistoric archaeological sites, including volcanic peaks that existed a long time ago. There are also areas along this route where they allow you to set up camp overnight. 

5. Route 50 or the U.S. 50

Route 50 or the U.S. 50 is the longest road you can take from the east coast to the west coast. This route is dubbed as the loneliest road due to miles and miles of mountains, sand, and sky. Route 50, which is about 3,200 miles, passes through the middle of the country, which is why it also earned the nickname, the Backbone of America.

The route starts in San Francisco and will pass through the deserts of Nevada and Utah, the Rocky Mountains of Colorado, the prairies of Kansas, and the fields of Missouri and Illinois. Indiana and Ohio. The route continues as you climb the Appalachians and pass through Washington, D.C.

The route ends in the fishing communities of Maryland. If you choose to walk across this road, you’ll be transported to the old version of America due to the old gas stations, diners, and buildings.

6. Great Western Loop 

The Great Western Loop is a 6,875-mile journey that links trails such as the Pacific Crest Trail, the Pacific Northwest Trail, the Continental Divide Trail, the Grand Enchantment Trail, the Arizona Trail, and the Sonoran and Mojave Deserts. These trails offer you a glimpse of the beauty of west America, the wilderness, the highest elevations in the U.S., and National Parks. At present, only one person has ever completed this trail, and he is the professional backpacker Andrew Skurka.

Conclusion – How Long Would It Take to Walk Across the US? 

The distance from the East Coast to the West Coast of the United States can vary from 2,800 miles to about 3,200 miles. This variation depends on the route you will take. The vertical distance of the United States is about 1,582 miles. But walking in a straight line across the United States is not possible due to privately owned properties that cannot be accessed.

Luckily, there are existing trails out there you can choose from depending on the scenery you want to see and the level of difficulty of the trail you want to take. Walking from one side of America to another would take about four to five months if you walked for about 18 miles a day in a straight line.

But walking in a straight line is not possible due to the terrain or private property. Therefore, a more realistic estimate for walking across the US would be about 6 months or more, depending on the route you take.

Remember if you plan to walk across the US, make sure that you have everything you need, such as a passport, credit card, water, walking stick, first-aid kit, batteries, flashlights, hat, cash, matches, or lighter.
