What is the difference between "tourism" and "travel"?

The difference between travel and tourism is:

Travel is about observing the scenery and things around you, traveling thousands of miles, reading thousands of books, rather than referring to individuals.

Traveling is about having fun, usually in groups, and is very short in time.

Travel is travel and sightseeing activities, also known as tourism. It is a complex social phenomenon. Tourism involves various social fields such as politics, economy, culture, history, geography, and law.

Travel is also a recreational activity. The World Tourism Organization defines travel as traveling at least 55 miles away from home.
