18. Mexico

Mexicans travel more domestically than any other country so far on our list. Large extended families, like in Italy, and the country’s long cultural history as the founder of multiple civilizations (including the Olmec, Toltec, Zapotec, Maya, and Aztec) play a major role in high domestic travel. Other nationalities have recognized the vivacity of Mexican culture and the numerous important cultural sites which bring in nearly 30 million tourists each year, making Mexico the tenth most visited country in the world.
