1 Best Sight in Buenos Aires, Argentina

Wedged between three busy Palermo streets, this unexpected haven has 18 acres of gardens filled with 5,500 varieties of exotic and indigenous flora. Different sections re-create the environments of Asia, Africa, Oceania, Europe, and the Americas. An organic vegetable garden aims to teach children healthy eating habits, and winding paths lead to hidden statues and a brook. The central area contains an exposed-brick botanical school and library, plus a beautiful greenhouse brought from France in 1900 but unfortunately not open to the public.
