Tour guides work in the travel industry, giving guided tours to groups of visitors. They are experts on the history of the location and offer their tour groups interesting or enlightening information about points of interest at nature attractions, historic sites, museums, scenic locations, and other travel destinations. Guides may give walking tours, bus tours, or even lead river tours on a boat. Often hired by visitors' bureaus or travel companies, tour guides are typically residents of the region in which they give tours. In starting it seems difficult but in actual its really interesting.
