HFE also owns aquariums near Philadelphia and Cincinnati, and the Ride the Ducks amphibious tours in a handful of cities, including Atlanta and Philadelphia. The firm touts that it offers family entertainment "with Christian values and ethics". The family-owned company was founded in 1950 by Hugo and Mary Herschend to manage the Marvel Cave in the Ozarks, a tourist attraction that opened in 1894.
