Have you ever gone on a trip to a new place and you got to go see all the cool places that make that place special? Like going to see the Statue of Liberty in New York or the Eiffel Tower in Paris? Well, some people like to go visit a different kind of place, called a terminal.
Now, a terminal is usually a big building where lots of airplanes or trains come in and out. So, terminal tourism is when people travel to visit these big buildings even if they're not planning on using a plane or train.
Sometimes, people take pictures of the cool architecture or interesting signs and advertisements around the terminal. They might also like to watch the people come and go, since there are always a lot of different types of people there from all over the world.
It might sound a little strange to some people, but hey, everyone has their own interests and things they like to do!
