Grant's Farm is best known as the place to see the famous Anheuser-Busch Clydesdales, but it is actually much more than that--it's a wildlife preserve. Comprised of over 281 acres, it houses close to a thousand animals, including exotic breeds like camels, zebras and elephants. Grant's Farm is the ancestral home of the Busch family, and before that, Ulysses S. Grant--so it's got history to spare. That's one of the main things that sets Grant's Farm apart from other free animal attractions like the Zoo and Purina Farms. People don't really understand the historical significance until they experience it firsthand. No wonder it's one of the most popular family and field trip destinations in the metropolitan St. Louis area. Admission is free, but you must pay to park, unless you park offsite or make other arrangements.
