I did not know there was a second zoo (besides Havana). Is there a third or fourth? I also did not know the one in Havana is so massive - 342 hectares!
I have been to Cuba and the zoos are mostly substandard even by Latin american standards. The large parque nacional zoo in havana seems to be better than the small city zoo in havana which i visited about ten years ago. The national aquarium was nice. The santiago zoo was said to be rather neglected.
Isn't there a large safari park-type zoo somewhere in Cuba where they have a bunch of large animals that they brought in from Angola?
