Toyota Motor Manufacturing Kentucky

Free plant tram tour, Georgetown, Kentucky Toyota's largest plant anywhere can turn out 550,000 vehicles a year, and the public tour costs nothing. That makes it the easiest first factory tour on this list, and one of the few where scale is the whole show: the Experience Center is pleasant, but the reason to come is the tram ride through the production floor. Reservations are required, so nobody turns up and joins. Tours run Tuesday to Friday at 9:30, 11:30 and 1:30. Children must be 8 or over and come with an adult, and over-18s need photo ID. Phones are not allowed on the tram and photos are strictly banned there, so leave everything in the car or a locker.
