It’s not every day you get to pet a tiger, feed a cub or ride a camel. Relish in such opportunities at Luj?n Zoo, named a 2014 TripAdvisor Travelers’ Choice attraction. The 37-acre (15-hectare) park is home to cougars, elephants, monkeys, sea lions, toucans and bears. Small children can delight in pony rides and watching farm animals like rabbits, chickens and goats scamper around. The admission ticket includes reentry, allowing you to go in and out for other city sightseeing around Luj?n. Bonus: Pickup and drop-off from centrally located Buenos Aires hotels are included.
