Recreation is an activity of leisure, leisure being discretionary time. The "need to do something for recreation" is an essential element of human biology and psychology. Recreational activities are often done for enjoyment, amusement, or pleasure and are considered to be "fun".
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. Tourism may be international, or within the traveller's country. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure, business and other purposes".
I sat on a toilet watching the water run thinking what an odd thing tourism is. You fly off to a strange land, eagerly abandoning all the comforts of home and then expend vast quantities of time and money in a largely futile effort to recapture the comforts you wouldn’t have lost if you hadn’t left home in the first place.

An important feature of Indian tourism industry is its contribution to national integration and preservation of natural as well as cultural environments and enrichment of the social and cultural lives of people. Over 382 million domestic tourists visiting different parts of the country every year return with a better understanding of the people living in different regions of the country. They have a better appreciation of the cultural diversity of India. It also encourages preservation of monuments and heritage properties and helps the survival of art forms, crafts and culture.
At its best tourism can provide an outstanding opportunity to increase the understanding of natural and cultural heritage, as envisaged by the World Cultural Heritage Convention while providing long term financial support to site management, local communities and tourism providers.
