Tour guiding involves leading visitors to attractions and providing interpretation, direction, and information about places. A tour guide acts as a leader, sales representative, mediator, and educator. They use tools like microphones, maps, and handouts to share their expertise about the destination's history, culture, and sites of interest with visitors. The role of a tour guide is to help visitors make the most of their limited time by selecting an engaging itinerary and sharing in-depth knowledge to enhance their experience.
