The modern day land tour consists of a group of tourists, usually around 40 or so in a group. The tour guides must lead the tourists on carefully planned itineraries visiting all the important and interesting places in a city or town. These can be bus tours, train tours, or walking tours.This evolved into tours of attractions for recreational purposes, with the first regular land tours in the United States being at Yellowstone National Park and the Gettysburg National Military Park. In Europe, during the 1840’s, Thomas Cook led the first tours of Paris, and soon after across the whole of Europe. England was actually the first country to train and regulate tour guiding as an industry and to this day, it remains an exciting and prestigious career option, especially for those who enjoy travelling.
