Parque General San Martín
Dating back to 1896, this 971-acre park has more than 50,000 trees from all over the world. Fifteen km (9 miles) of paths meander through it. You can stop and smell the roses (a dedicated garden contains hundreds of varieties), observe aquatic competitions from the rowing club's balcony restaurant, or set the kids free on the numerous playgrounds. Scenes of the 1817 Andes crossing by José de San Martín and his army during the campaign to liberate Argentina are depicted on a monument atop Cerro de la Gloria (Glory Hill), a steep 20-minute walk up from the park's center. The stadium here (built for the 1978 World Cup, which Argentina won) hosts popular soccer matches; the amphitheater (capacity 22,500) fills to the brim during Vendimia, the annual wine harvest festival; and there are markets and open aerobics classes on the weekend.
