Tour guides lead individuals and groups around places of interest, explaining their history, culture, architecture, wildlife or local character. In the UK, they may work in cities, countryside, historic sites, museums, galleries and visitor attractions, or accompany tours between destinations. Tours can be delivered on foot, by coach, boat or other transport, and may follow a set route or be tailored to a group's interests and access needs. Typical services include guided walks, sightseeing tours, heritage and architecture tours, food and drink experiences, nature and wildlife outings, and commentary for coach or private group tours. Guides may provide practical information about the route, landmarks and local customs, answer questions, and help groups keep to a schedule. Some specialise in particular subjects or locations, and some hold recognised professional qualifications such as the Blue Badge, while qualifications and experience vary across the sector.
