In Benidorm they try to be a Themed Park.
The exhibits for Asia are "camouflaged" like humans buildings (Indian Maraha Palace) for big cats, and intent for "Agrah Red Fort" in the ungulates praire (like blackbuck, barasingas, and axis deers mainly) but others like camel dromedaires and asian elephants too.
In the Central-South America's area, the buildings resembled at pre colombine structures. For me, the best exhibit in this area it's the walk throught aviary. With a good amount of birds, but titis and marmosets too.
The reptile house it's indoor of a fake volcano.
Elche in general, seems a old zoo,that they try to improve...But with a few good exhibits ( not the best yet, but...) for orangutans or white lions.
I hope this can help you.
