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've taught the better class of tourist both to see and not to see; to lift their eyes above and beyond the inessentials, and thrill to our western Nature in her majesty.

Slow travel now rivals the fly-to-Barcelona-for-lunch culture. Advocates savour the journey, travelling by train or boat or bicycle, or even on foot, rather than crammed into an airplane. They take time to plug into the local culture instead of racing through a list of tourist traps.
