Palermo is the largest and greenest barrios in Buenos Aires. Area attractions such as the Jardín Botánico, El Zoológico, Jardín Japonés and the Planetario Galileo Galilei all offer families a break from city touring. But Palermo offers more than an opportunity to relax; it is also one of the city’s most dynamic neighborhoods. Head to the trendy Palermo Viejo for hip restaurants and cutting-edge design.
