The Zoo in Madrid is one of the best in the world, and it is a combined zoo/aquarium. It is located in the Casa de Campo park and that is also the name of the nearest metro station. Inside the zoo you can see tigers, dolphines, sea lions, parrots, elephants, snakes and other interesting animals. It is also possible to get a picture of you together with a snake and so on (of course for an extra charge).
The zoo is quite expensive. An adult ticket costs around 18 Euro. You should be warned that the zoo is on a big territory, so if you plan to see everything you need quite some hours.
