At Lujan Zoo you can walk with the animals 

Luj - An hour west of Buenos Aires in Argentina is a spot where tourists don't often visit. Lujan Zoo will give the visitor more memories than just Tango lessons. When you go to Buenos Aires and get tired of the Tango, churros or empanadas, then catch the number 57 bus westward to Lujan. Waiting for you are lions and tigers and bears.
