9 of the Longest Journeys You Can Take Around the World


Sometimes, you just want to stretch your journey out as long as possible. So try putting some of the world’s longest journeys on your bucket list. Whether it’s a 17-hour flight or a 740-step escalator, here are nine extra-long rides you can take to make your vacation superlative.


China’s Danyang–Kunshan Grand Bridge, part of the high-speed railway between Beijing and Shanghai, stretches more than 102 miles long over the Yangtze River Delta. However, only a little over 5 miles is over open water. 


If bridges over land seem a little passé, China also hosts the world’s longest bridge over open water. The 26.4-mile-long Jiaozhou Bay bridge took the title from the longtime record holder, Louisiana’s Lake Ponchartrain Causeway, in 2011. But after complaints from Louisiana that the Jiaozhou Bay bridge cheated by using curves to increase the length, Guinness deemed Lake Ponchartrain Causeway the “Longest Bridge over Water (Continuous)."

While there are several competing claimants to tallest, one of the best is the escalator in Moscow’s almost 30-story deep Park Pobedy station: It has more than 410 feet of moving stairs, with 740 steps. The ride is about three minutes long. In the Western Hemisphere, travelers have to settle for the D.C. Metro’s Wheaton Station escalator, which stretches 230 feet [PDF]. 


The Australian airline Qantas currently runs a nonstop flight between Sydney and Dallas-Fort Worth. It traverses almost 8570 miles and takes nearly 17 hours on the westbound flight. But Emirates might be poised to take the title away, with a planned nonstop route between Dubai and Panama City that will cover 8580 miles and take as long as 17.5 hours. Service starts in February

Shanghai’s metro system is just over 340 miles long, the longest city subway network in the world. However, Beijing plans to expand its subway system to about 406 miles by the end of 2016. (At 600 miles, Seoul’s system is considerably longer, but it’s run by multiple operators over a large area.)


New York City-based public radio station WNYC pegs the longest possible subway ride on one swipe as a 155-mile journey underground between the Bronx and the Rockaway Peninsula in Queens. Going from Wakefield-241st Street to Far Rockaway requires 54 transfers, and only the most intense subway lover would ever want to complete it. (For reference, you could travel between the same points with one transfer over the course of two hours, but brevity is not the point here.)

One of the biggest issues facing architects trying to build mile-high skyscrapers: current elevator technology can only go so high. The world’s tallest conventional elevator ride right now is inside Dubai’s 2717-foot Burj Khalifa, the tallest building in the world. To get to the tower’s highest floor, you have to take an elevator almost 1655 feet straight up, reaching top speeds of about 22 miles per hour. The building’s emergency elevator is even longer—it travels nearly 1900 feet. 


The longest dead-straight road in the world is Highway 10 in Saudi Arabia, at 162 miles long. In second place is Australia’s Eyre Highway, a 90-mile stretch without a curve in sight. Bring a few particularly gripping podcasts to listen to, because there won’t be much else to pay attention to. 


According to Guinness, the longest train journey is the 6346 mile semi-regular Moscow, Russia to Pyongyang, North Korea route that takes almost eight days. This route is not currently approved for Westerners to enter North Korea through, though, so most people have to make do with the nearly 5780 mile Trans-Siberian Railway from Moscow to the far eastern city of Vladivostok.

The U.S. National Park System comprises more than 400 sites, 62 of which are national parks. Within the parks, visitors can explore forests, deserts, volcanoes, and more. But even with the diversity the National Park System has to offer, many visitors find themselves going to the same iconic parks year after year. To see the most-visited national parks in 2019, check out the list below.

This list comes from recreational visitation data gathered by the National Park Service. It doesn't include national monuments, parkways, or similar units—just the sites with the official "national park" designation.

The Great Smoky Mountains tops the list with roughly 12.5 million visits last year. Stretching across five counties in North Carolina and Tennessee, it's less than a day's drive away for one-third of the U.S. population. The accessibility plus the free admission and gorgeous mountain scenery help make it the country's most popular national park.

It's followed by Arizona's Grand Canyon National Park, which saw 5.97 million visits in 2019 to witness its world-famous views. Colorado's Rocky Mountain National Park takes third place with 4.7 million visits, and Utah's Zion National Park takes fourth with 4.5 million. Read on for the full top 10.

The National Park Service was established just over a century ago, and it's amassed a fascinating history. Here are some more facts about the United States's national parks.
