An excursion is a trip, usually made for leisure, education, or physical purposes. It is often an adjunct to a longer journey or visit to a place, sometimes for other (typically work-related) purposes.
Short excursions for education or for observations of natural phenomena are called field trips. One-day educational field studies are often made by classes as extracurricular exercises, for example, to visit a natural or geographical feature.
The term is also used for short military movements into foreign territory, without a formal announcement of war.[1]
