The Children's Museum of South Dakota seeks to transform the world by inspiring generations to love learning and believe that life is full of possibilities. We spark imagination for all children and their grown-ups through play, creativity, and discovery. With more than 44,000 square feet of indoor play space on 4 acres of prairie, we tell the story of our connection between land and culture in the Midwest region. Guests are encouraged to use their imagination and explore using more than 5,000 lose parts and props, but we may be most famous for housing the country's largest animatronic dinosaur, Mama T. Rex.
