Travel is the movement of people between relatively distant geographical locations for any purpose and any duration, with or without any means of transport. Travel also includes relatively short stays between successive movements. Movements between locations requiring only a few minutes are not considered as travel. As an activity, "travel" also covers all the activities performed during a travel (movement).
Travel may be local, regional, national (domestic) or international. In some countries, non-local internal travel may require an internal passport, while international travel typically requires a passport and visa.
Travel can be for recreational purposes, for tourism, to visit people, for business or for commuting, and may occur for numerous other reasons, such as to obtain health care, migration, fleeing war, etc. Travel may occur by human-powered transport such as walking or bicycling, or with vehicles, such as airplanes, private transport, public transport, automobiles and trains.
A round trip is a particular type of travel whereby a person moves from his/her usual residence to one or several locations and returns. A trip can also be part of a round trip.
