what are the differences between mainstream tourism and special interest tourismno

Mainstream tourism is relatively unspecialized. The
tourist who wants to "get away" but doesn't have any specific desires to see a
particular area or be involved in particular kinds of activities while on vacation is
looking for a mainstream kind of experience. There are no critical requirements for the
trip - the goal is to simply go somewhere new or different and engage in activities
other than the routine ones for the traveler.

Special
interest tourism covers the whole range of travel possibilities that focus upon some
particular area or interest. A tourist who wants to spend his/her vacation studying the
lifestyle of a particular type of animal may choose to go on a trip to the area where
that animal lives, using the services of a guide to locate and learn more about the
creature. Tourists who are committed to environmental issues may choose to spend their
vacation working to rebuild eroded trails, clean polluted waters or shores, or collect
samples of soil or water for testing and evaluation by sponsoring scientific groups.
Tourists who want to experience new or extreme activities may vacation with others while
climbing mountains, biking extraordinary distances or locations, scuba diving in remote
areas, or other activities that are not easily arranged.
