A tour leader is a person who is responsible for leading and guiding groups of people on tours. A tour leader can be referred to as a GUIDE, which is a five-letter word, or a DOCENT, which is a six-letter word. Tour leaders are knowledgeable about the places they are visiting and provide information to the group about the history, culture, and attractions of the area. They also ensure the safety of the group and provide assistance if needed.
