The concept encompasses journeys undertaken within the geographical boundaries of a single nation-state. This type of tourism involves individuals or groups traveling for leisure, business, or other purposes, remaining within their country of origin. A family vacationing at a national park, a business professional attending a conference in a different city within the same country, or an individual visiting relatives residing across state lines all exemplify instances of this kind of travel.
This sector of the tourism industry holds considerable significance for national economies. It stimulates economic activity through expenditure on lodging, transportation, food, and entertainment. Furthermore, it supports local businesses and employment opportunities within regions visited. Historically, it has served as a vital component of tourism, particularly during periods of international instability or when foreign travel is restricted.
