The northern tip of Parque do Estado is given over to the Jardim Botânico , a well-tended botanical garden that includes a promenade of imperial palms, an orchid farm, picturesque ponds, a stand of brazilwood trees and a herb garden where you are encouraged to smell the aromatic flowers and leaves. An open-air café offers snacks, plus a simple but fresh and well-prepared per-kilo buffet lunch (R$25 per kg).
