Outside Buenos Aires is the exceptional zoo, Parque Temaikén. Only the most charming animal species are on display (think meerkats, pygmy hippos and white tigers), roaming freely around natural enclosures. An excellent aquarium comes with touch pools, and plenty of interactive areas provide mental stimulation. Taxis from the center take about 40 minutes, or grab bus 60 marked ‘Escobar’ from Plaza Italia.
