Tourism is an important socio-economic activity. It provides enormous scope for economic development of a particular area. 

According to Ziffer (1989), "Tourism involves travelling to relatively undisturbed or uncontaminated natural areas with the specific object of studying, admiring and enjoying the scenery and its wild plants and animals, as well as any existing cultural aspects (both past and present) found in these areas."

In India, temple towns, historical monuments and sea beaches were traditionally sought out as tourist attractions. But now the fabric of tourism is changing rapidly as nature, heritage, and recreational destinations are gaining more importance. In this background, eco-tourism has of late become a top attraction for the tourists. 

The root of tourism in India can be traced to pilgrimage. In the early stages, pilgrimage-based tourism was only of domestic nature but during recent years, a large number of foreign tourists have also started visiting places of pilgrimage. India has an unending choice for the tourists-a 3,500 km long and 8,848 beautiful long beaches on the sea coast, gregarious tropical forests, the great variety of lifestyle. India's share in international tourist arrivals was 0.34 per cent in 2002 and it increased to 0.49 per cent during 2005.

The increasing trend has been maintained over the last three years and international tourist arrivals touched 3.92 million in 2005. The World Travel and Tourism Council have identified India as one of the foremost growth centres in the world in the coming decade. Domestic tourism is estimated to be much higher than international tourism and has also been rising rapidly.

The Tenth Plan recognised the vast employment generating potential of tourism and the role it can play in furthering the socio-economic objectives of the Plan. Tourism is the third largest net earner of foreign exchange for the country. Tourism in India has vast employment potential. By 2015, it is expected to provide 25 million jobs
