St. Louis Aquarium at Union Station

Union Station used to be a fish out of St. Louis’s water—we’re here to reestablish its sea legs. Being at the heart of Union Station’s revival, we’ve proudly developed the cure to St. Louis’s landlocked blues: a 120,000-square-foot aquarium, packed to the gills with over 13,000 animals across 44 exhibits. Guests at our new St. Louis Aquarium can explore aquatic life from sea to shining sea, without venturing out of the 63103 ZIP code. We’re reel-y excited to embark on this journey with you. Plan your visit to the St. Louis Aquarium and discover our amazing galleries and interactive exhibits, including our 250,000-gallon shark habitat.
