Known locally as Los Bosques de Palermo (Palermo Woods), this 400-acre green space is really a crazy quilt of smaller parks. Lush grass and shady trees make it an urban oasis, although the busy roads and horn-honking drivers that crisscross the park never let you forget what city you're in. Near the lakes in the northwestern part, some 12,000 rosebushes (more than 1,000 different species) bloom seasonally in the Paseo del Rosedal. A stroll along the paths takes you through the Jardín de los Poetas (Poets' Garden), dotted with statues of literary figures, and to the enchanting Patio Andaluz (Andalusian Patio), where majolica tiles and Spanish mosaics sit under a vine-covered pergola.
South of Avenida Figueroa Alcorta, you can take part in organized tai chi and exercise classes as well as impromptu soccer matches. You can also jog or rent bikes, in-line skates, and pedal boats. The park gets crowded on sunny weekends, as this is where families come to play and have picnics. If you like the idea of the latter, take advantage of the street vendors who sell refreshments and choripan (chorizo sausage in a bread roll) within the park. There are also several posh cafés lining the Paseo de la Infanta (running from Libertador toward Sarmiento in the park).
