I love this zoo so much! The tickets you bought are reasonable. So many different animals, some I have never seen before, like white tigers, dolphins etc. The variety of animal displays/shows are wonderful, but dolphins are just breathtaking! The dolphin show is one of the most amazing things I've ever seen. I don't speak Spanish so I don't understand what people are saying but you don't need to speak Spanish to appreciate it. The aquarium is great, there are lots of different kinds of fish and then you can go to the big aquarium with lots of sharks. My whole holiday in Madrid was great but the zoo is the best so far. I 100% recommend you to come here
