This attractively landscaped zoo is located slap bang in the heart of the Casa de Campo. The animals look as happy as can be expected of beasts held in captivity, although the big cats could really do with a bit more leg-room, but it's certainly a good option for a day out with the kids. Among the more than 6,000 animals of 500 different species, the most popular are the panda bear and the gorillas. At the Tierra de Gorilas ('Land of Gorillas') a sheet of reassuringly thick glass separates you from the massive, glowering silverbacks that prowl about. Children will enjoy walking through the shark tank and dolphinarium. There is also a petting zoo and a train ride.
