This is part of the Ringling Museum grounds and entry comes with the regular ticket (you can buy extra upstairs entry there as well). The ground floor is included. Lovely grounds and great view of the water. Definitely see this while at the Ringling Museum and don't forget to view all of the films about the Ringlings. Very interesting.
