A walking tour is a tour of a historical or cultural site undertaken on foot, frequently in an urban setting. Short tours can last under an hour, while longer ones can take in multiple sits and last a full day or more. A walk can be led by a tour guide, as an escort.
A Grand Tour was "a long tour of major cities" undertaken in Europe in the 17th through 19th centuries, as part of a wealthy young man's education, and involved visits to cities, historic and cultural sites, with pedestrian activity confined to these cities or sites.
A pilgrimage is a religious journey traditionally taken on foot, to a location of significance to the walker's faith. Only a minority of contemporary pilgrimages are on foot. Chaucer's 14th-century narrative poem Canterbury Tales certainly indicates that a pilgrimage can involve pleasure.
There are also similarities between walking tours that involve long hikes and backpacking, while non-pedestrian backpacking is a kind of modern, inexpensive Grand Tour that makes use of public transport.
A walking tour is generally distinguished from an escorted tour by its length and the employment of tour guides, and can be under 12 hours, or last for a week or more. They are led by guides that have knowledge of the sites, or the landscape, covered on the tour, and explanations and interpretations of the site can cover a range of subjects, including places with historical, cultural and artistic significance. Walking tours, of various kinds and length, are universally part of the tourism industry, and can be found around the world.
Many walking tours involve a payment to the guide, although some operate on a tip system. The "pay what you want" model started around 2004, and can be found in many countries. The UK-based Guild of Registered Tour has criticised the system for not requiring any training or certification of its guides.
Several cities now have groups that are employing dramatic spectacle to add interest to their tours. Usually guided by actors in costume playing a role, these walking tours create the feel of living history as guests walk in the footsteps of those who came before them. These tours, which blend history and dramatic narrative, share "history in a non-academic, very accessible fashion."
