France — 89.4 Million Visitors

More people are visiting France than any other country in the world, and the country has a 100-million-visitors target for 2020. Think they'll hit it? We do, too, especially considering it hosted the FIFA Women's World Cup earlier this year.

Not only does France receive the largest number of tourists, but they make the most off of them too. Tourism brought in $62 billion last year!

Get your visit in while you can. Tourism is only going to rise, especially when France hosts the 2024 Summer Olympics in Paris.

Must-See in France

Mont Saint-Michel, a UNESCO World Heritage Centre in Northern France, is a sight truly like no other: a medieval monastery perched atop a solitary island.

Spain — 82.7 Million Visitors

Many news outlets are reporting on the extreme over-tourism found in Barcelona, which hit a record 8 million visitors in 2018. But that represents just a tenth of the travelers who visit this expansive country that also includes the cultural hub of Madrid and the flamenco capital of Seville, as well as untouched countryside and gorgeous beaches.

The nation's largest tourist groups come from Germany and Britain, though people from these countries are increasingly heading to Turkey and Greece instead. In their place, Americans are filling the empty beds, with nearly 3 million people coming from the U.S. last year — an 11.8 percent growth.

Unfortunately, the influx of people has locals on edge, and the Spanish are considered to be developing "tourist phobia," especially in Barcelona and the Catalan states.

Must-See in Spain

Forget the tourist cities and hike the Camino de Santiago, known as "The Way," for a pilgrimage across northern Spain.

United States — 79.6 Million Visitors

Considering the United States is 3.8 million square miles, nearly as big as all of Europe, it's easy to see why it's the third-most-popular travel destination on Earth.

The country's mix of wildly diverse attractions don't hurt either, including some of the most iconic cities in the world (New York City, LA, Chicago) and a thriving national-park system.

Must-See in United States

China — 62.9 Million Visitors

Not only does China receive more visitors than most of the world, but its own inhabitants account for 10 percent of all world travelers. It is expected that 20 percent of the Chinese population — 300 million people — will have passports by 2027. Chinese tourists also spend more than any other country, nearly doubling that of No. 2 — a whopping $277 billion!

Those outside China who make their way to the country discover everything that comes with being the world's oldest continuous civilization, from villages dating back thousands of years to ancient marvels like the Great Wall. Plus, the nation's cuisine, as affordable as it is flavorful, can't be beat.

Must-See in China

Zhaoxing Village is flanked by mountains and touts five drum towers representing five good manners in Chinese tradition: benevolence, righteousness, courtesy, wisdom and trust.

Italy — 62.1 Million Visitors

Tourism is so big in Italy that long lines at places like St. Paul's Cathedral and the Colosseum in Rome are all but guaranteed, even if you've booked reservations in advance. Statistics show Italy's tourism growth is above the European average, with Rome attracting nearly 27 million of its visitors.

Europeans travel to Italy the most: Germans account for 14 percent of visitors, with French and UK visitors making up 3 percent each. Americans are the biggest overseas market, also at 3 percent.

Outside the throngs of Rome, Italy also boasts the rolling vineyards of Tuscany, the artistic pedigree of Florence, the natural wonders of the Amalfi Coast and the canals of Venice among its embarrassment of riches.

Must-See in Italy

Get away from the throngs by visiting Sicily's ancient ruins and temperate beaches. Go now before it becomes overcrowded too; Sicily saw more than 7 percent growth in tourism last year.
