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".
Contribution to World Heritage objectives, Tourism development and visitor activities associated with World Heritage properties must contribute to and must not damage the protection, conservation, presentation and transmission of their heritage values. Tourism should also generate sustainable socio-economic development and equitably contribute tangible as well as intangible benefits to local and regional communities in ways that are consistent with the conservation of the properties.
